Personality
Like her canon counterpart, Celica is a kind, generous, and sociable person who deeply loves her sister and friends. She is a sentimental individual who maintains a firm stance that all life is precious and will use her healing magic to assist those in need of it, regardless of who or what they are. She is also shown to be selfless to the point that she will shield a person with her own body without any hesitation. It has also been noted by people (particularly Bloodedge) that she has no sense of direction, which usually ends with her getting lost.

She is also shown to be very stubborn, such as when she ignores her sister's warnings and heads to the store by herself to buy some groceries and is also hard to her to admit that she has a poor sense of direction, leading to frequent quarrels between her and Ragna.

It is currently unknown if her and Ragna's relationship is far beyond the one of a mother and son.
