hi oomf!!!! and thats hard to say... heres a list of some and what i like abt them:

Meursault- i think his personality (the bit he shows of it) is charming! i also like how you can never really tell what he's tthinking? as if hes always monologueing in his head...

Monaca Towa- her cruelty mainly, but also her psyche. given everything we're told about her ingame, it makes me curious on how her brain works! the affects of trauma on her psyche, esp compared to other characters like kotoko jotaro etc, esp in their own unique brand of cruelty. Idk if this makes sense, but shes fun to think about!
