This Is (Not) Danganronpa!

You wake up in the middle of a room, remembering nothing...
You meet people who are in the same situation as you...
Some stuffed mascot tells you that to escape, you need to kill someone and remain undetected...
You promise that neither of you will kill anyone... And then you're immediately in a class trial, where you find out who the killer is, because he decided to hide the murder weapon in a trash can...
