Issei Hyoudou (Solarverse)

Issei Hyoudou is the main protagonist of Highschool DxD, as well as the fanfiction story, Highschool DxD: Rise of the Solar God.

Unlike the original depiction of Issei Hyoudou, this version exists in an alternate universe in which he is born from the essence of the Shinto Goddess of the Sun and Universe Amaterasu.

History
Dreading that Takamagahara, and by extension the rest of the supernatural world would be detrimental to her child, Amaterasu sent the infant Issei to live on Earth, where he is found in the Ise Grand Shrine by Mitsuru and Sachiko Hyoudou.

Initially unbeknownst to Issei himself, many dwellers of the supernatural world have all been aware of his existence, and seek either to challenge him, kill him, or to convince him to join their allegiance, much to Issei's own dismay.

Because of this, Issei has come in contact with many of the creatures of the supernatural world. Such entities include the Ouroboros Dragon Ophis; who would mark him as her mate at the age of six, the Apocalypse Dragon Great Red, and much later on, a female incarnation of the Supernatural World.

Appearance
Issei is a 17-year-old high school student of average height with brown hair, with two short locks of hair behind his head. Initially, he was born with heterochromia, and as a result, had different colored eyes. His left eye was a doe-brown color, while the right eye was a yellow-orange sun-like shade. After he unlocked his full power and made peace with himself, his right eye gained a brownish hue. He is noted for having a innocent face, but later adopts a sterner disposition, and gains a more muscular and toned build. His common attire is a white, short-sleeved dress shirt with black highlights, black pants, and brown dress shoes. However, Issei leaves his dress shirt open, and wears a red T-shirt underneath it.

Six months later, Issei’s attire consists of a black V neck shirt with black pants, and black shoes. He is noticeably much taller than he was before, and his facial features have sharpened as well. On occasion, he wears his short-sleeved dress shirt over his current attire.

Personality
"He's like the Sun. All of the planets that reside in space; they surround and orbit around it. But as they continue to move, they pay no attention to the Sun at all. They never get close to it. And yet the Sun...it just chooses to stay there and endure through it all."

- Sachiko Hyoudou comparing Issei to the Sun.

In contrast to the original Issei Hyoudou, this Issei initially possesses a shy and reclusive nature, and is often alluded to being an introvert. As a child, Issei was noted by Sachiko to be somewhat quiet and melancholic, and she believed that his behavior was solely affected by the cycle of the Sun. Whenever the Sun was present in the sky, Issei was livelier and more energetic, while during the times when the Sun descended, he became reclusive and rarely uttered a word. His inability to fully interact in most social situations, along with occasional lapses of literal-mindedness, are his most irrevocable, and occasionally endearing traits.

Hidden beneath his gentle demeanor lies a great amount of rage that is a result of all the bullying and harassment he endured since he was a child. This hidden fury finally manifested itself when Issei transformed into the first stage of his solar evolution against Riser Phenex. When his rage was fully unlocked, he became a person of pure overwhelming fury with murderous intent.

Overtime, Issei's personality has changed to that of a neutral loner, and wishes to be left to his own devices. However, this behavior is often challenged due to the presence of the many people who have interacted with him. When around his family and allies, Issei shows an honorable and gentle spirit, and maintains an unwavering desire to protect the people around him.

Issei possesses vengeful tendencies, and is shown to be capable of apocalyptic wrath; characteristics often seen in Gods and Buddhas. He is more than willing to bring great pain and suffering to whoever wronged him or his family without hesitation. Such cases include bisecting Fallen Angel Kokabiel for desecrating the Ise Grand Shrine and threatening Issei when he refused to join the Fallen Angel's plan to start a second Great War. After this encounter, Kokabiel became deeply traumatized and suffered through great pangs of terror while he was sealed in Cocytus. His loss against Issei wounded his pride and resolve so heavily, that he referred to Issei as "the most terrifying being he had ever come in contact with".

Another case was the Evil Norse God Loki who threatened Issei's life out of a need to prove his superiority. This ended with Loki's defeat at the hands of Issei, who had stabbed Loki in the back with Fenrir's fangs. In both cases, Issei was nearly close to killing Kokabiel and Loki, and was only stopped from doing so due to the arrivals of Vali Lucifer and Rossweisse; respectively.

Although his wrath is one of the sources of his innate power, it has also become a flaw of his. Due to this, it can be inferred that Issei simply does not know how to "walk away" from certain situations. It should also be noted that while Issei, when pushed to his emotional threshold, is more than willing to destroy beings who have threatened him or his family, he is not one who relishes in the act of doing so. In spite of all that, Issei has shown that he is able to forgive some of the beings who have antagonized him if he is subjected to their vulnerable side; with Izanami-no-Mikoto being the most prominent example.

Aside from the drastic change in his behavior, Issei retains his compassionate nature, his uneasiness when getting involved in social situations, and his unawareness of well-known sayings, often taking things rather literally out of context. On the other hand, he adopts a brutal and serious nature and is an utterly ruthless individual in battle. He opts to subject his enemies into humiliation, but will inevitably seek to destroy them in the end. He is also prone to thinking of clever strategies on the fly, a habit that has so far shown to be in his favor.

Issei is shown to have no qualms in forming brief alliances with beings who were at some point, his enemies, showing that he is able to put aside his grudges. Though this tolerance solely depends on the situation at hand, and who the individuals are. He (with the help of the Yamata-no-Orochi) was able to successfully convince the Evil Dragons Crom Cruach, Grendel, and Aži Dahāka to temporarily assist him in his ongoing struggle against Amenominakanushi, the first Kami of Shintoism. Even Cao Cao, the leader of the Hero Faction, aligned himself with Issei, but with the original intention of wanting to know why the True Longinus chose Issei's will over his own (though earlier on, Cao Cao had sent his team members Georg and Leonardo to help Vali in his fight against Amenominakanushi).

Due to being a God that was raised on Earth, Issei is a rather self-effacing and humble person, harboring no traces of arrogance or hubris; typical traits that are also shown in Gods and Buddhas. If anything, he is a reserved and modest person and doesn't like to bring attention to himself. As such, he is not a confrontational individual by any means. He is also fully aware that there are many beings who are far stronger than himself, and fully acknowledges that he is not the most powerful existence. As a result, he will try his best to distance himself away from potential conflicts, and will only fight back the moment his loved ones and allies, as well as the Earth and the Supernatural World are harmed.

Issei is also a person who gives off the vibe of not having concern for his own well-being, but rather for the lives of others; specifically for the ones he cares about. This has grown to the point that the one and only time he's worried about himself is because of him wanting to make sure he is at least strong and conditioned enough to protect others.

According to Leiko Hyoudou, Issei has an inferiority complex, in which he believes that he is incapable of being good enough to do much of anything, despite his various achievements. As a result of this line of thinking, he is extremely adamant in refusing to ask for assistance from his allies, and feels that doing so would make him a burden to them, much to their worries. He has also shown brief instances of having self-deprecation. Though it was not Issei's intention for it to happen, his tendency to put himself in danger has caused Ophis' possessiveness over him to grow, in part due to her worry and anger towards Issei for being reckless and not having concern for himself.

Though he doesn't express it often, Issei is an individual who carries a great amount of guilt and remorse within him. One prominent example of this, was the death of Riser Phenex, who was destroyed by Issei after the former tricked the latter into believing that he had killed Leiko in order to bring out Issei's latent strength. After Riser's death, Issei suffered an emotional breakdown, unable to cope with the fact that he committed murder for the first time. Upon reuniting with Riser's spirit in Death's Domain, he admitted that killing him was one of the worst things he had ever done, and made it abundantly clear that he didn't enjoy it. Though he and Riser have made peace with each other, Issei's guilt never dwindled, and instead manifests in his vow to protect Riser's peerage, and his personal request to transport Riser to the Third Heaven. He even admitted to Vali that the weight of his guilt never lessened, and in spite of how heavy it was, he had no intention of severing ties with it, hinting at an inability to let go of the past.

Overall, Issei can be best described as a Heroic-Neutral protagonist, as he is a person who is perfectly content with being left alone to himself, but will interfere the moment a dangerous threat looms over his homes, his allies and loved ones. He can also be classified as a Reactionary Hero, as the beings he has fought are usually the ones to invoke his ire, prompting him to retaliate in turn.

Power
"How can someone so infuriatingly naive and idiotic, be powerful enough to destroy a God whose power was among the Top 10 Strongest Beings in the world?! It doesn't make any sense! This child! He is too dangerous now!"

- Grim Reaper Pluto's thoughts on Issei Hyoudou. As a Shinto God born from the energies of the Sun, Issei is considered to be one of the strongest existences on the planet Earth, as well as the Supernatural World. At the moment of his birth, the immense energy emanating from Issei was felt by the likes of Devils, Angels, Fallen Angels, and even the Dragon God of Nothingness and the True Red Dragon God Emperor.

Even by the standards of Gods and Buddhas, Issei was said by others to be unnaturally powerful, his natural strength far superior to the ranking of Ultimate-Class Devils, Fallen Angels, Angels, and Grim Reapers. Amaterasu stated that Issei's powers grew tremendously due to her sending him to Earth, allowing his physiology to adapt to the planet's atmosphere. When Mitsuru and Sachiko Hyoudou discovered the infant Issei in the Ise Grand Shrine, his wails were powerful enough to induce tremors that shook the shrine. At the age of six, Issei's power had grown to the point that he was able to manifest an energy aura that was strong enough to severely burn a human's hand.

At the time when he fought Riser Phenex, the Seraph Gabriel pondered that Issei's power was comparable to the might of Michael, an Archangel. Serafall Leviathan also mused that Issei had enough force to destroy the entire Underworld. He was also shown to be strong enough to damage Sirzechs Lucifer, a Super Devil. The immensity of Issei's power was showcased after he defeated the Fallen Angel Kokabiel, with the latter referring to him as "the most terrifying being he had ever come in contact with".

With the Sun as his primary source of power, Issei's strength continued to increase throughout the story through unlocking new transformations, and meeting the Welsh Dragon Ddraig and the Evil Dragon Yamata-no-Orochi, both beings sealed in the Kusanagi-no-Tsurugi.


 * Statements by Author

God Beyond Solar Issei is "infinitely stronger" than all of his previous transformations.

Morning Star Issei possesses unfathomably colossal energy.


 * Fighting Style

Issei's fighting style primarily consists of perceiving the movements and battle capabilities of his opponents, and countering them with vicious and brutal attack patterns. He is a very observant and astute fighter, as shown during his battle against Loki. When Loki revealed that Fenrir's fangs possessed God-Killing properties, Issei immediately sought to rip one of the fangs out of the wolf's mouth, and stab Loki in the back, heavily damaging the Evil Norse God.

During battle, Issei adopts a frighteningly quiet nature, rarely uttering a single word to his opponents. He often immerses himself in his own thoughts on how to keep the battle to his advantage.


 * Main Flaws

He is mostly naive in his everyday life, making him and the ones he wants to protect an easy target for pragmatic beings who hold an agenda towards him. Issei, while occasionally trains himself, does not strive to become the strongest, therefore he leaves much of his potential unused.

Anything that can nullify his stellar power or block his ability to absorb stars and star-like objects, would render him vulnerable (but not entirely powerless). He is also vulnerable to the Chains of Heaven, the weapon used by Gilgamesh, the King of Babylonia, to restrain the Mesopotamian gods. Due to Issei's overwhelming strength, the chains were equally powerful enough to hold him down; as the stronger a deity is, the harder the chains are.

Due to his naivete, Issei has instances of being manipulated and 'played like a lure', which was exploited by Amenominakanushi when he possessed Takami-musubi and took advantage of Issei's desire to protect the innocent.

Issei tends to live in the present and the near-past, rarely looking forward into the future or the distant past, which makes his knowledge extremely limited.

Attributes=

Attributes
Immense Godly Power: As the child of Amaterasu, Issei wields a vast amount of godly power. His sheer strength is noted enough to rank him as one of the strongest beings of the Shinto Faction, and arguably the most powerful being on planet Earth. As an infant, his power was great enough to be sensed by the inhabitants of Heaven, the Underworld, and the Dimensional Gap.

Immense Strength: Issei is endowed with enormous physical strength, sufficient enough to overpower even the most formidable creatures of the Supernatural World with minor effort. While the level of his strength seemed extraordinary by human standards after growing up with them, by the standards of Gods and Buddhas, Issei's power is considered to be extremely monstrous and overwhelming. He is shown to be strong enough to overpower the likes of Riser Phenex, Fallen Angel Kokabiel, the Evil Norse God Loki, Susanoo-no-Mikoto, and much later on, Indra; who was a God with Ultimate-Class power.

Expert Hand-to-Hand Combatant: Issei is a highly capable unarmed fighter. While mostly relying on the Kusanagi-no-Tsurugi in battle, he is not above using unarmed attacks to surprise and incapacitate his opponents.

Highly Perceptive Combatant: Despite his naivety and literal mindset, Issei is a very insightful and crafty fighter. He quickly realizes mistakes in his own battle tactics and corrects them, and almost instantly adapts to his opponent's battle tactics to perfectly counter them.

Indomitable Will: Arguably Issei's most phenomenal trait, is his extraordinary willpower towards adversity. Even when up against an opponent that was more than enough to give him trouble, Issei has more often than not continued fighting no matter the cost. The moment someone has antagonized Issei in any way, he will immediately pursue them, and will absolutely not stop no matter how many obstacles get in his way.

Teleportation: Issei is able to travel almost anywhere instantly without occupying the space in between.

Apportation: He is able to apport himself and anyone else nearby to anywhere he chooses with the snap of his fingers.

Astral Projection: Though he has not showcased this ability as of yet, Issei is able to display the wings of Ddraig and the Yamata-no-Orochi through a form of astral projection, showing them through his shadow. One of the reasons Issei does this is to signify his status as a possessor of Dragons.

Telekinesis: Issei is able to impart kinetic energy on matter with his mind.

Immense Stamina: Due to being a Shinto God, Issei's stamina is tremendous, as he is able to use the power of the Two Heavenly Dragons, and an Evil Dragon without suffering any ill-sided effects.

Regenerative Healing Factor: Issei can heal from any bodily damage given to him completely so long as one cell or even molecule remains. The level of his regeneration increases drastically if he is near the Sun or a star.

Absorption: Issei has the ability to absorb anything that retains solar and/or light essence, as shown during his battle with Riser Phenex. Issei also employed this ability during his fight against Kokabiel, in which he absorbed the Fallen Angel's light spear, which was the size of Kuoh Academy. When his body is physiologically altered to that of a star, he is shown to be able to absorb the stars in space.

Illusion: Issei has shown the ability to cast mirages of himself, in order to catch his opponents off guard. He employed this technique during his battle against Loki.

Solar Power: As a God born from the energies of the Sun, Issei can absorb solar energy, and this in turn augments all of his powers and abilities. Due to being on Earth for years and having adapted to the planet's environment, Issei is far more powerful than most solar deities.

Soul Transfer: By utilizing Ddraig's transfer ability, Issei possesses the power to transfer a portion of his soul into an inanimate object in order to prolong his existence.

Power Multiplication and Transference: Ddraig's ability, which allows Issei to multiply his own power, or transfer that augmented power to anyone or anything.

Belief Empowerment: As a God that was raised on Earth, the level of Issei's potential is somewhat dependent on the thoughts and beliefs of humans. As a result, it is hinted that the genuine love the Hyoudou family have for Issei remains a contributing factor in his growth.

Limited Star Creation: Due to him becoming a stellar energy being; a.k.a a living star, Issei is able to channel his energy out of his being and form a small star. Similar to how Issei's power increases after he consumes the energy of a star, the same thing applies to a star's size if he were to pour his energy into it.

Purification: Due to having the innate ability to manipulate solar energy, Issei is able to cleanse the soul of an entity. He first used this ability in unison with the God from the Bible in order to alter the morality of the Apocalyptic Beast Trihexa. This resulted in 666 becoming far less malevolent than before and much more subdued. The second time he employed this ability was against Izanami-no-Mikoto, with the effects of his purification being powerful enough to reverse the damage done to Izanami's soul, which was caused by the hazardous atmosphere of the Shinto realm Yomi. This allowed Izanami to return to her former self, with her mind and soul now free from Yomi.

Dormant Abilities
Venomous Blood: As a result of containing the Yamata-no-Orochi's soul within him, Issei has access to the Dragon's abilities. True to its name, the Yamata-no-Orochi contains a deathly lethal poison within its fangs; with the poison being dangerous enough to taint a victim's soul. The Yamata-no-Orochi, not knowing how her poison would affect Issei, intentionally withheld this ability from her carrier, and kept it a secret from him. Issei would later on discover this ability after his third encounter with the Evil Dragons Crom Cruach, Grendel, and Aži Dahāka.

Though this ability is powerful, it is dangerous to implement, as the poison must be injected into Issei's bloodstream in order for him to manipulate the substance. In addition, Issei himself is not immune to the venom, putting his soul at risk; though due to being the Yamata-no-Orochi's host, its effects on his soul are delayed for a short period of time.

Light Based Weapons Generation: As a God who was born from the Sun, Issei has a natural affinity to light-based powers, and thus has the potential of generating powerful light spears. This ability is similar to the powers of Angels and Fallen Angels.


 * -|Transformations=

Super Solar
The first evolution of Issei's solar transformations. This form was achieved by Issei during his battle against Riser Phenex in a bout of rage.

While in this state, Issei's hair spikes up in a orange-yellow or golden color, and he loses the pupils and irises in his eyes. His body is surrounded by a golden aura.

In this form, he easily overpowered Riser, and was strong enough to inflict great damage to Kokabiel, who possessed power that was equivalent to that of a Satan-Class Devil. Issei was also capable of combating against the Evil Norse God Loki with little to no effort, before the former transformed into his Hell-Fire state and proceeded to overwhelm Loki.

Super Solar・Evolution
After becoming a stellar energy being, Issei retains the ability to utilize the original Super Solar transformation in conjunction with his God Beyond Solar state. Though most of the characteristics of the form remain unchanged, Issei's hair changes to a gold-white color, rather than the previous orange-yellow color. While it is essentially the same transformation, this state could also be referred to as Super Solar・Evolution (スーパーソーラー・エボリューション Sūpāsōrā eboryūshon).

Due to Issei previously mastering the traditional Super Solar form before the alteration of his physiology, he is able to retain this state for as long as he needs to without any drawbacks, and can remain transformed indefinitely on an almost subconscious level.

Hell-Fire/Phoenix Transformation
Issei gained this state by absorbing Riser's flames while he was in his Super Solar form. In this form, his hair reverts to its normal style, though it is black in color. His left eye returns to the color of brown, while his right eye acquires a black-grayish color. On occasion, phoenix wings of pure hell-fire would sprout out from his back. In this form, Issei gains the attributes of the Phenex clan, with the exception of being able to produce Phoenix Tears.

Issei's power in this form was shown to be large enough to damage Sirzechs Lucifer, and overpower the Evil Norse God Loki without much effort on Issei's part. Because he attained this form by absorbing Riser's flames while he was in the Underworld, Issei can only access the transformation whenever he is in the location, and therefore, cannot transform into it on Earth or Heaven.

Berserk Transformation
The bizarre transformation that is a result of Issei becoming overwhelmed by the anger he has suppressed over the years. Following many traumatic events, the Solar God's wrath grows exponentially without him being aware of it and as he is being tested by the personification of Death, he slowly begins to succumb to his raw emotions. This causes the manifestation of his anger to fully emerge, reforming Issei's body into a monstrous demon-like creature with pale skin and a skull-like head. Issei achieved this form during his final encounter with Susanoo's spirit, and quickly overwhelmed the Storm God, before the lost souls of Death's Domain devoured the latter.

This form possesses formidable strength and adds further augmentations to Issei's power. But due to the unstable nature of it, Issei's own solar energy could quite literally 'burn' him from the inside out the long he is in the berserk state. Later on, after Issei overcomes his anger, the 'berserk' aspect of Issei's being seems to have been vanquished.

Super Solar God
The initial final evolution of Issei's solar transformations, which was gained by him absorbing the Sun entirely into his body. While in this form, his hair lifts up slightly and is now a reddish-purple color. His eyes are sharpened, and his irises gain a red shade to them. He is also much taller and thinner compared to his previous transformations, and is surrounded by an explosive and flame-like aura.

Issei first used this form to fight against his cousin and opposite Yoru-no-Mikoto, who had absorbed the Moon in order to fight on equal grounds with the former. Later on, Issei would employ the use of this transformation once more to fight the Heavenly Emperor Indra.

God-Killer
A form that is entirely separate from his regular solar evolution line, God-Killer is a form that Issei achieves as a result of stabbing himself with Fenrir's fang, which is stated to be able to kill Gods and even the most powerful beings. When imbued with the essence of Fenrir's fang, a black coat of energy forms around Issei's body, with his hair gaining a black shade and his eyes changing to a blue color. In this form, he gains a double aura which consists of a smoky-like black aura combined with his own blood.

Dead Star
Dead Star Issei (死んだ星一世 Shinda Hoshi Issei) or Black Hole Issei is a unique transformation obtained by Issei in the midst of his most dire moments. After suffering an inevitable defeat by the hands of the Central Master of Shintoism and being thrown into a black hole, Issei managed to form a plan on how to effectively help the solar deities, call for assistance, and deal with Amenominakanushi himself. The birth of this transformation came about from the following steps.

First, as Issei's body was being destroyed from the black hole, he, with the help of Ddraig, the Orochi and the clone of Albion, sealed a portion of his soul into the Kusanagi-no-Tsurugi blade. During this action, the clone of Albion divided the energy of the black hole into the sword. This caused the remnant of Issei's soul to merge with that energy and become a being with the same physiology. Then the portion of the Solar God's soul managed to gain consciousness on its own, and began to pull numerous of stars across the Universe into it, empowering the soul even more. Finally, the soul manifests into a form of solid black substance with glowing eyes.

As for the form's power, because Issei was for all intents and purposes, a black hole, and had also consumed the energies of at least a dozen sun-sized stars, the form is suggested to be far powerful than even his Super Solar God transformation. With the ability to consume all finite amounts of energy, along with his augmented strength, Issei managed to overpower Amenominakanushi (one of the highest ranked gods in terms of power) with little to no difficulty. Amenominakanushi even fleeted from the battle at some point, possibly suggesting that Issei may have even surpassed him in strength.

Weakness(es)
The name of the form speaks for itself. While it is indeed a powerful transformation, it does have its drawbacks. Firstly, the form itself was 'born out of death', suggesting that it is not a completely stable transformation. Secondly, as Issei states: "The only thing it can do is die...", which is confirmed by him constantly dripping blood and feeling the intense pain in his body. And finally, possibly the most dangerous drawback the Solar God has had, is that with all of the factors combined into one, in the end, Issei would be plagued with a true death sentence. If he were to proceed to fight with this form, he would've eventually disappeared completely from existence without even a single aspect of him remaining. Even if Amenominakanushi wouldn't have been able to, time would've surely destroyed Issei.

God Beyond Solar
"You know, it's strange, really. Out of all the things I've turned into, I didn't think becoming a star would have this much of an impact. What's even weirder is that I'm only in my normal state.

What do you mean?

Well, it's just...back then, in order for me to access my full power, I had to absorb the Sun entirely. But now this body might be strong enough to the point that I might not even have to absorb it this time."

- Issei to Cao Cao after the former's body attained the physiology of a star.

This is the form Issei assumed after his body was physiologically altered to that of a star. When Issei achieved this transformation, his skin gradually peeled back and ripped wide open, revealing the vibrant golden-white energies within him. After this, the immense amounts of excess energy burst forth from Issei's body, thus causing his rebirth into a being with a more powerful physiology.

While in this state, his power greatly eclipses that of his previous transformations, and thus any other forms he achieves are augmented as well. In this form, his physical appearance remains mostly unchanged, while his body is imbued by a golden glow, and a double blazing aura of blue and white.

Because it was achieved as a result of Issei's body structure changing to the essence of a star, the transformation is essentially Issei's new and permanent 'natural' state, which prevents stress and agitation from hindering him. It should be noted that while he has become a stellar energy being, Issei still has access to his original Super Solar transformations, and as such can further strengthen himself by the utilizing the forms on top of the God Beyond Solar state.

This form is alternatively known as "The God that surpasses the Sun", or Evolved Issei.

Morning Star
This form is the result of the synchronization between Issei's God Beyond Solar state, and the energies of the red supergiant star UY Scuti. In this form, Issei's hair spikes up and adopts a light pink hue in color, with the hair possessing pure-white highlights. The strands of hair that hang down in this transformation are spiked up with the exception of three bangs, which dangle in front of his forehead. Another peculiar characteristic of the transformation is the small but distinguishable wisp of hair that juts out from the rest of Issei's hair. His facial features are sharper, and his eyes are more menacing and change to a dark green-gray color.

Much like the God Beyond Solar form, the power of this transformation is emphasized by a double aura effect, placing a dark fire-like orange aura outside of a crimson-red aura. The outer aura is violently fluctuating and jagged while the inner aura maintains a gentle, flame-like appearance. The aura is also accompanied by bio-electric sparks, and Issei's body is surrounded by an ominous black glow.

It is hinted that the hair color in this form was originally white, as Cao Cao noted that Issei's aura when absorbing UY Scuti was pure-white, and that in turn mixed with the red color of the supergiant star, causing it to turn pink.

Due to Issei's transition from a solar deity to a stellar deity, this state is essentially a new cycled version of his original Super Solar transformation. Cao Cao referred to this form as Super Star, or Super Stellar, though it was most likely stated in a bout of curiosity and jest more than anything.

Flaws
Despite its seemingly tremendous increase in power, the transformation possesses setbacks as well. This drawback was hinted when Issei noticeably had trouble absorbing the energies of UY Scuti, with him worrying about the notion of trying to fully absorb the red supergiant star into his body.

Because he was unable to absorb UY Scuti entirely into his system, along with the fact that this transformation possesses intense energy that he isn't used to holding, Issei theorizes that he'll start to experience a severe decrease in stamina due to not being adjusted to the form. In order to bypass this flaw, Issei is able to release massive surges of energy from his body, lessening the strain, but not completely depleting the setback.

Additionally, a requirement needed to sustain this form is mental fortitude. If Issei starts to become overwhelmed by rage or stress, his energy becomes unbalanced, therefore losing the compensation needed to prevent the amount of pressure the form puts on his body.

Name: Hyoudou Issei, Solar God, Red Dragon Emperor (Sekiryuutei), Solar Dragon Emperor, The God That Surpasses The Sun, Morning Star.

Origin: Solarverse

Classification: Shinto God with Solar and Stellar Physiology

Gender: Male

Age: 17

Power and Abilities: Superhuman Physical Characteristics, Master Hand-to-Hand Combatant, Master Swordsman, Pyrokinesis, Heat Manipulation, Solar/Stellar Ki Manipulation, Flight, Afterimage Creation, Energy Absorption, Reactive Evolution (Becomes stronger from being damaged), Reactive Power Level (becomes stronger the longer he is in combat), Regeneration (Likely Low-Godly), Immortality (Types 3, 4, and 8), Teleportation (Via Instantaneous Movement), Telekinesis, Telepathy, Energy Sensing, Transformation (can transform to increase his power even further), Soul Transferal and Power Augmentation (with the fragment of Ddraig and the Yamata-no-Orochi's souls sealed within the Kusanagi-no-Tsurugi, he is able to boost his own power and transfer a portion of his soul to survive), access to all five Demon Swords.

Weaknesses: Initially, if the Sun is either shielded by an eclipse or destroyed, his body is unable to absorb any more solar energy, leaving him powerless | When his body becomes a star, this weakness no longer hinders him. Has the risk of burning out in the form of a induced supernova if his energy overwhelms him | If used for a long period of time, the form plagues him with intense pain and shaves off his life force, due to being a fusion between a Holy Sword and five Demon Swords. Inability to manipulate his stellar energy harmonically with the chaotic energy of the Paradoxical Scale Mail would result in all of the energy imploding directly upon Issei's being, similar to a supernova.

Physically able to compete with Susanoo, an ultimate-class god, without his solar energy.) | Star Level (far stronger than six months ago. Able to stall a heavily augmented Indra.) | Large Island level (greatly increases Issei's overall strength, speed and durability.) | Large Star level (Should be far higher than his time-skip base form.) | Planetary Level (Managed to hold and reflect a planet-sized attack from Amenominakanushi.

Notable Techniques:
 * Super Solar (スーパー太陽): A unique and formidable advanced transformation assumed by Issei, which augments his base attributes by a great magnitude. The Super Solar form is succeeded by two further transformations; Hell-Fire/Solar Phoenix Form (which was achieved by Issei absorbing the flames of Riser Phenex) and Super Solar God (the result of him fully absorbing the Sun into his body). Later on, Issei's body was altered to the physiology of a star, and as a result, he is granted an astronomical power-up, along with new transformations; God Beyond Solar (his new and permanent base state), and Morning Star Issei (gained by him absorbing the red supergiant star UY Scuti).


 * Instantaneous Movement: Issei places his index and middle fingers on his forehead, and instantaneously moves from one point to another. He can also perform this technique by snapping his fingers.

Kusanagi-no-Tsurugi
Ame no Murakumo no Tsurugi (天叢雲剣, lit. "Sword of the Gathering Clouds of Heaven") is a Holy Sword of Shinto legends that rivals the original Excalibur and Durandal. It is also known as the Kusanagi no Tsurugi ("Grass-Cutting Sword"). Unlike the other Holy Swords, that are said to be forged by God, the Ame no Murakumo no Tsurugi was found inside the body of the legendary 8-headed Evil Dragon, Yamata no Orochi.

The Ame no Murakumo no Tsurugi was originally a gift handed to Amaterasu by Susanoo as a sign of the latter asking for his sister's forgiveness. Years later, around the time of the Great War, the Angels, Devils, and Fallen Angels interrupted the battle between the Welsh Dragon Ddriag and the Vanishing Dragon Albion, causing the Dragons to attack the leaders of the Three Factions. In retaliation, the leaders destroyed the Dragons' bodies, and opted to seal them. However, while Albion was sealed in the Divine Dividing Sacred Gear, Ddraig was sealed in the Kusanagi-no-Tsurugi by Amaterasu, marking him as the second soul to be sealed in the Kusanagi, the first being the Yamata-no-Orochi.

The Holy Sword is currently in the possession of Issei Hyoudou, with the Red Dragon Emperor and the Yamata-no-Orochi assisting him in his battles against the creatures of the Supernatural World.

Appearance
While its standard form is a regular Holy Sword, the Kusanagi-no-Tsurugi can also take the form of a Black Dragon Armor with red jewels, due to it encasing the spirits of two Dragons. When infused with Grendel's scale, the jewels change to a dark green hue, representing the color of the Crime Force Dragon.

Gauntlet
In this form, the Kusanagi-no-Tsurugi takes the form of a black, claw-shaped armored gauntlet with a crimson-red jewel on top of the palm area.

Kusanagi no Tsurugi: Scale Mail
The 'Balance Breaker' of the Kusanagi which creates a Black Dragon Armor with red jewels. It covers Issei's body and strengthens his powers and abilities. The armor has a pair of retractable Dragon wings that grants Issei an alternate way of flight.

Kusanagi no Tsurugi: Dividing Gear
The Dividing Gear resembles the Kusanagi's gauntlet form, but is white in color and has a blue jewel. With Dividing Gear fused with the Kusanagi, Issei gains all the powers of Divine Dividing.

Issei obtained this form when he placed one of the jewels from Vali's armor to his, creating the Dividing Gear. This allowed him to use Albion's dividing powers. Initially, unbeknownst to Issei, the jewel from the Divine Dividing Sacred Gear contained a fragment of Albion's spirit, with the soul serving as the embodiment of the Dividing Gear's abilities. Later on, the portion of Albion's soul is returned to Vali, and thus, Issei no longer has this ability.


 * Not Yet Unlocked

Kusanagi no Tsurugi: Grendel's Scale
The result of merging Grendel's sphere-shaped scale into the Scale Mail armor of the Kusanagi-no-Tsurugi. While this armor retains the same appearance as Issei's regular 'Balance Breaker', the jewels are a dark-green shade instead of the usual red.

In this state, the defense capabilities of the Kusanagi-no-Tsurugi: Scale Mail increase on an exponential level, due to the properties of Grendel's scale being incorporated into the armor. As a result, Issei's endurance and durability is greatly augmented. A unique feature this form possesses due to having Grendel's scale as the base of its power, is the new armor grants Issei knowledge and access to all of Grendel's abilities. Despite the great advantage, the armor also drains Issei's stamina, and the moment it is depleted, it will dissipate.

Partial Manifestation
Due to having the souls of the Red Dragon Emperor Ddraig and the Yamata no Orochi, they are able to manifest outside of the Holy Sword. When the Yamata-no-Orochi's power is released, the sword sprouts all eight heads of the Dragon, and they are able to breathe fire, and contain the Dragon's deadly lethal poison. When Ddraig is called out, he is able to be summoned into battle temporarily.

Trivia
Issei's use of the Kusanagi-no-Tsurugi (with the sword containing the spirits of both Ddraig the Red Dragon Emperor and the Yamata-no-Orochi), strengthened by Issei's own solar abilities, derives elements from the character Genryūsai Shigekuni Yamamoto from the anime and manga series Bleach.

Demon Swords
"Quick, what was Siegfried doing before you captured him?

What?

What was Siegfried doing before you took him to your team for interrogation? Was he fighting someone or something beforehand?

Yeah, he was fighting Hyoudou. But why is any of that important?

He was fighting Issei Hyoudou? Oh no. No, no, no, no, no, no!

What is it? What does Siegfried fighting Hyoudou have to do with the Demon Swords?

Don't you get it?! The Demon Swords didn't show any signs of rebelling against Siegfried before he fought Issei Hyoudou!

So what are you saying?

I'm saying that perhaps all five of the Demon Swords have chosen Issei Hyoudou as their new wielder."

- Georg and Vali Lucifer, discussing about Siegfried and the Demon Swords.

Gram (グラム, Guramu): The Demonic Emperor Sword, and the Sword of the Sun. It is a Dragon Slayer sword with massive destructive power, and is sharper than most Holy Demonic Swords. Georg reveals that after Siegfried's battle with Issei Hyoudou, Gram was the first of the Demonic Swords to reject Siegfried, and choose Issei as its new wielder.

Balmung (バルムンク Barumunku) is a Demon Sword from Norse mythology with a drill-like aura. It is capable of creating powerful whirlwinds.

Dáinsleif (ダインスレイヴ Dainsureivu) is a Demon Sword that creates huge pillars of ice from the ground.

Nothung (ノートゥング Nōtungu) is a Demon Sword that specialises in sharpness.

Tyrfing (ディルヴィング Diruvingu) is a Demon Sword that specialises in destruction.

Drawbacks
The most notable negative attribute of the Demon Swords is that similar to Samael, they are cursed and whoever wields them may become affected by its lethal effects.

Demonic Kusanagi
The Demonic Kusanagi, also known as The Paradoxical Kusanagi, is a powerful Holy Demonic Sword that is formed by the union of the Kusanagi-no-Tsurugi and all five of the Demon Swords; Gram, Balmung, Nothung, Tyrfing, and Dáinsleif.

Overview
The Demonic Kusanagi wields tremendous offensive power that far exceeds its components, possessing all of their abilities expanded to no visible end. As a result of the souls of Ddraig and the Yamata-no-Orochi existing within the Holy Demonic Sword, the Demonic Kusanagi retains the ability to create a Dragon Armor that surpasses its Holy Sword component.

Sealed
The sealed form of the Demonic Kusanagi appears as a curved broadsword with a crimson jewel embedded into it. Due to its structure resembling a greatsword, as well as its weight, Issei's movements are more limited than with the normal Kusanagi blade. This is the Demonic Kusanagi's weakest and least efficient form.

Initial Release
The Demonic Kusanagi in its released form greatly resembles the Durandal, as one of its components is a Holy Sword itself. It is a uniquely-shaped broadsword with a black blade and a crimson-red edge. Like the Durandal, this sword has a semicircular guard on the left side of the handle that extends to the bottom just above the pommel, with a small extension on the right side of the handle.

Final Evolution
In its evolved state, the Demonic Kusanagi resembles the Mjölnir, the hammer of Thor the Lightning God of Norse Mythology. The Holy Demonic Sword takes the appearance of a giant hammer with a black outer frame with a red structure throughout its entire design from the head to the handle. There is a Norse symbol on its middle piece, with the mark representing one of the Demonic Kusanagi's components, Balmung.

Paradoxical Scale Mail
Though it shares similar features to the Kusanagi-no-Tsurugi: Scale Mail, the Scale Mail of the Demonic Kusanagi is muscular and bulkier. The armor and hair are black with glowing crimson-red highlights, and the eyes on the armor are red as well. The 'ears' give the impression of straight angled devil-horns.

The biggest contrast it has compared to the Kusanagi-no-Tsurugi: Scale Mail, is that this particular armor has a face with blazing red eyes and a mouth full of sharp fangs. The pauldrons also have teeth and horns like those on its head, and it has red glowing crystals on its hips. The armor is also able to sprout out large wings that have the appearance of a universe-like substance.

When Issei uses the holy properties of the Demonic Kusanagi in unison with the godly aura from his stellar physiology, the Paradoxical Scale Mail's glowing crystals, eyes, and highlights change to a bright blue-white hue, signifying his attempt to balance the energies.

This is the Demonic Kusanagi's strongest and most efficient form.

Abilities
The Demonic Kusanagi possesses the abilities of the Kusanagi-no-Tsurugi (carrying the souls of the Red Dragon Emperor Ddraig, and the Yamata-no-Orochi), and the five Demon Swords; Gram, Balmung, Nothung, Tyrfing, and Dáinsleif.

Due to its nature as a Holy Demonic Sword, it greatly augments Issei's attributes, in part due to him being a God, and imbues him with demonic powers. When merged with the Demonic Kusanagi in its Dragon Armor state, Issei's physiology is temporarily altered, and as a result, he is transformed into a Divine-Demonic being. While in the armor, Issei undergoes an astronomical increase in power, far eclipsing his natural transformations, and the Kusanagi-no-Tsurugi: Scale Mail.

As a result of having experience with the abilities of the Kusanagi-no-Tsurugi, as well as being of divine lineage, Issei is able to draw out the massive power of the Demonic Kusanagi to its greatest extent, due to the balance between its opposite holy and demonic components.

Devouring Sorrow
When donning the Paradoxical Scale Mail armor, the Yamata-no-Orochi's poison within Issei undergoes a powerful evolution. Due to his ability to forge objects of light, it is possible for Issei to meld them with the enhanced poison.

In order for the amalgamation to take place, the weapon must be in contact with the poison that is deeply embedded in Issei's bloodstream. By drawing his blood, Issei can manipulate the flow of the venom to envelop any weaponry of light. This can result in the creation of haemo-toxikinetic spears, arrows, swords, etc., that are reddish-pink in color, and surrounded by a blood-red aura.

Weaknesses
When in its Dragon Armor state, the Demonic Kusanagi retains the Demon Swords' detriment of devouring the user's lifespan as long as they remain in the armor. Because this Dragon Armor is a fusion of five Demon Swords and only one Holy Sword, the consumption of the user's life-force is quintupled, placing them in a great amount of agony and strain. While Issei is able to bypass the danger to his life-force by employing his godly power as proxy, he still feels intense pain within the armor.

Conversely, this weakness has the effect of a double-edged sword, as Issei becomes much stronger from any pain or damage inflicted upon him, leaving him in a paradoxical state of chronic agony and regeneration. This trait dramatically increases Issei's raw might after instantly recovering from the pain done to him.

However, while Issei grows more powerful from the damage he takes, he has a limit to how much he can endure. Therefore, if he cannot withstand the amount of pain inflicted upon him, the armor will dissipate, rendering him defenseless. The amount of power he gained from the armor's effects, will then rebound on him, leaving Issei with a heavily damaged body.

Due to the armor inheriting the side-effects of its demonic components, using it in tandem with the Super Solar transformation is detrimental to Issei, as the form would cause the holy and demonic properties within the Demonic Kusanagi to become imbalanced, resulting in Issei's body breaking down from the strain. Also, whatever damage Issei receives, combined with the continuous depletion of his life force from donning the armor, disrupts the energy control needed to sustain his transformations, which could potentially lead to him burning out in a supernova-like state.


 * -|Morning Star Halo=

Morning Star Halo
The Morning Star Halo is a double halo of light with five spikes that was created by the effects of the True Longinus' forbidden form, The Truth Idea. It was granted to Issei by the blessing and will of the God from the Bible.

Effects
The Morning Star Halo imbues its user with several powers, due to it being blessed by the will of the God from the Bible, and they retain these abilities so long as the halo is present.


 * Unbreakable Skin: The Morning Star Halo grants its user with formidably dense skin that is impervious to harm.


 * Immunity to Samael's Curse: Due to being created by the effects of the True Longinus; with the Longinus containing the will of the God from the Bible, the user is unaffected by Samael's poison, as it is God's Curse.


 * Energy Containment: The Halo also allows Issei to store massive portions of the energy from his transformations when he is not in combat, so that his reserves wouldn't be wasted quickly.

Weaknesses
Despite its immense power, Issei's body can only sustain the halo for a brief period of time. It is also possible for it to be destroyed, rendering Issei without any access to its abilities.

Influence
Despite his young age and being an individual who initially did what he could to avoid the world of the supernatural, Issei's presence has nonetheless made a substantial impact on the world, as well as the planet Earth. Due to him possessing a Heavenly Dragon Emperor and an Evil Dragon, and being affiliated with the Ouroboros Dragon and the Apocalypse Dragon, supernatural beings have come to be much more aware of his existence. In spite of his non-confrontational and arguably pacifistic mindset, Issei's influence has left both a positive and negative effect on the world around him, with him gaining allies and enemies alike.

At the beginning of his life, the creatures of the supernatural world had already sensed the dormant power within him. His human parents, Mitsuru and Sachiko Hyoudou, as well as his adoptive cousin, Leiko Hyoudou, all had a brief inkling of Issei's nature, often comparing him to the various aspects of the Sun. Upon his arrival to Kuoh Academy, Rias Gremory and Sona Sitri, sensing his immense potential and initially unaware that he was a God, already had plans of enrolling Issei into their peerages. Azazel, who had also taken an interest in Issei, ordered Raynare to watch and observe him.

Issei himself has saved the inhabitants of the Earth, as well as the planet itself from numerous counts of destruction. For instance, his battle against Kokabiel became well-known throughout Heaven and the Underworld, with Serafall Leviathan and Gabriel thanking Issei for (in his case, inadvertently) preventing the Fallen Angel from starting a Second Great War. Issei's participation in the battle against Qlippoth has earned him a partial leeway to making personal requests, such as asking Michael and Gabriel to transport Riser Phenex's soul and the spirits of the Hyoudou children to the Third Heaven, with both of the requests being granted by the Angels.

Hobbies
In his free time, Issei either watches the Sun disappear into the night, or watches it rise up in the sky; both habitual activities he retained from his childhood.

He also shows a liking for reading manga; specifically, the Drag-So-Ball manga, a hobby he shares with his neighbor Morisawa. At times, he rides motorcycles with the Great Red, and has taken a hobby of bicycling at night. On occasion he often spends time with the members of the Occult Research Club and the Student Council.

Trivia

 * This version of Issei is often referred to as Solar God!Issei, or Solar!Issei, to differentiate from the original Issei Hyoudou. His new title, due to his body becoming the physiology of a star, is Stellar!Issei or MorningStar!Issei.


 * Post-Timeskip Solar!Issei (in which the timeskip is six months after the battle against Rizevim) prominently shares his appearance with Toshiki Kai from Cardfight!! Vanguard, as a way to show Issei physically maturing with age.


 * Issei is often referred to as an unintentional cougar's prey, a reference to him being the object of affection and/or interest of older women/primordial entities who have taken feminine form.


 * Solar!Issei is not only an alternate universe counterpart to the original Issei Hyoudou, but could also be considered as the alternate counterpart to Ama-no-Oshiho-mimi, who is the actual son of Amaterasu in the original Shinto Mythos. Their connection is also ironic, as Amaterasu sent Ama-no-Oshiho-mimi to rule over the Earth, with the latter refusing the task due to the many disorders that occurred on the planet. Solar!Issei on the other hand, lives on Earth, and has consistently saved the planet on many occasions.


 * Much like the original depiction of Issei Hyoudou, this Issei possesses an appreciation for breasts, specifically Ophis' breasts. Although he is not as obsessed or enthusiastic about them as the original Issei is, he often rests his head on Ophis' breasts when feeling sleepy, with him saying that they're as 'firm as pillows', and also referring to them as 'big marshmallows'.


 * Like his original counterpart, Issei's name means "Sincere/Honest". His surname Hyoudou means "regular soldier". While this is originally in reference to the original Issei Hyoudou being a Pawn, as pawns are considered as regular soldiers in chess analogy, it could also be interpreted as Solar!Issei being a 'soldier' for the Earth and the Supernatural World. As a result, his full name translates to "Sincere or honest regular soldier".


 * Issei's decision to wear dark clothes is due to black clothing being able to absorb sunlight easily.


 * Issei is ranked as the 6th most powerful entity in his Universe.

Personality and situational wise, this version of Issei Hyoudou is similar to that of the title character of the movie John Wick:

Both characters are well-known in their respective Universes for being living legends (though it is recent and ongoing in Issei's case), with very rare individuals having enough sense of mind to not trifle with them.They are genuinely polite and well-meaning protagonists, but can shift into utter brutal and ruthless combatants who are willing to kill whoever wronged them. They mostly remain to themselves and do not bother anyone in their specific Universes, but will immediately retaliate when someone antagonizes them personally. Wrath is their greatest flaw, as they have shown an inability to simply 'walk away'.

A trait this Issei shares with his original counterpart, is the fact that he has also died more than once:

He first died in his battle against the Shinto God of the Storms Susanoo, due to Issei being weakened by the Solar Eclipse. This prevented him from being able to recover from the wounds Susanoo inflicted upon him.His second death was a result of his body disintegrating from the black hole that was summoned by Amenominakanushi. This would lead to his soul descending into Yomi, the Underworld of the Shinto Faction.This incarnation of Issei is often referred to as Solar God!Issei, or Solar!Issei, to differentiate from the original Issei Hyoudou. His new alias, due to his body becoming the physiology of a star, is Morning Star!Issei.Issei's ability to transform from the use of his solar powers is based on that of the Super Saiyan transformations from the series Dragon Ball Z. Also, his use of the Kusanagi-no-Tsurugi (with the sword containing the spirits of both Ddraig the Red Dragon Emperor and the Yamata-no-Orochi), strengthened by Issei's own solar abilities, derives elements from the character Genryūsai Shigekuni Yamamoto from the anime series Bleach.
