In Danganronpa V3: A Merry Christmas, Shuichi Saihara is shown to be the same as he was at the end of the killing game.

It's later revealed that he has become more shaken up and depressed after the killing game even with all his friends revived and has become very insecure with himself. Shuichi is also seen to be uncomfortable around his revived friends.

Shuichi's Fate (A Merry Christmas)
After everyone wakes up, Shuichi is backed into a corner by the others and demanded a reason for his actions. Shuichi leads them all outside to see that he and the Monokubs prepared gifts for everyone and the mystery was meant to be a distraction until the snowstorm happened and Shuichi lost control of the situation. After being forgiven by his friends, the sled carrying their gifts is blown up by Monotaro accidentally. Afterwards, Shuichi spends the entire night with his friends at the Christmas party.
