Chihiro Fujisaki
Chihiro Fujisaki is the Ultimate Programmer and has a meek and timid personality. Chihiro's personality and small figure causes him to gain a fanbase and eventhough he is a boy, he dresses up as a girl which is a big reveal after his murder. He mainly dresses like a girl because when he was younger, he got harassed and bullied a lot which led to him developing a "weak complex" so, to stop the bullying, he dresses as a girl and lived his life as one. He got murdered because Monokuma threatened to reveal everyone's darkest secret unless someone is killed. His secret was the fact that he was actually a boy and instead of falling into despair out of fear of his secret being revealed, he wanted to change himself for the better so he started training at night in the gym with Mondo, which he considered the "manliest". Even after his death, he provided aid by secretly programming an AI called Alter Ego which ended up being a huge help to the group of survivors, including saving Makoto from dying as he was about to be falsely executed.
