I think the only one who truly knows what any of the rules are is Enoshima-san. Her AI version appears to be a spitting image of her true self from what I can discern and from what we all know, Monokuma-san always loved to change the rules to match whatever whim he'd taken.

Komaeda-san doesn't shrink from her either. I attempted to stay away from her, but there's something there that makes that too difficult for me. Unlike Hinata-san, I cannot just ignore her.

Sometimes I wish I had that luxury.
