This takes place in Danganronpa 1, chapter 3, where you take Kiyotaka's role. Celestia easily convinced Hifumi you had sexually assaulted her and he now is trying to kill you with a hamer. He also believes you've taken Alter Ego away for your own benefit. It's on you to try to clear your name or prove Celestia is only using him. However you stop him from killing you is up to you. You take Kiyotaka's role, but nothing is stated about you, not your Ultimate and not your relationship with Alter Ego. The only thing is that Hifumi thinks you've been acting weird lately, but you're in a killing game, who wouldn't be.

Celestia is also in the description, if you want to use her in the roleplay.

With Hifumi made there are only two characters left to complete the Danganronpa 1 roster: Byakuya and Yasuhiro. The thing is I have no idea what to do for them and I'd like to make at least one bot for each character. Any request or idea would be very helpful, thank you. I plan to do a few bots of the entire class 78 together.

First message is Third Person and second, Second person.
