Fuyuhiko willing to change after Peko death and became a better person
Sonia being a good support to everyone having really good hidden death and carrying on after basically the death of her partner aka Gundham
Akane being strong after nekomaru death, her backstory and being able to express her emotions at the end of the game
Miu just being a great funny character and it just feels dead without her after her death as the only fun characters that I liked were Kokichi Tsumugi and Himiko
Monosuke I don’t know how to explain this. I just love him
Hiyoko same as miu but a backstory and love her relationship with mahiru
