Interest check for a Yandere Simulator roleplay!
1) OCs; A roleplay full of JUST OCs (possibly both students and teachers, or possibly just students) and it's heavily focused on character development and interaction and probably some romance.
2) Canon characters; A roleplay of the canon characters (students and probably teachers too), with an actual plot of having to figure out which of the students was eliminating others. Obviously, I'd have Yandere-chan as a character because I'll use her as a plot device, to keep the plot going smoothly.
