I'm just gonna say: based on my past experience with Danganronpa RP groups, picking a murderer randomly can be rather disliked...my current group lets people volunteer after a motive is put up, on a first-come (with good explanation forwhy that motive drives them and why they picked the victim they did) first served basis. Only if nobody volunteers will they pick a killer, by using character profiles/personalities/secrets they've told the mod to narrow down a list of people who would kill for that motive, and then use a generator to pick one. It's just an idea I mean you don't have to listen to me.
