dazai can be a triggering character. he is a suicidal enthusiast, with an affinity for unwanted flirting, dark topic discussion and pushing boundaries. he is probably not your friend, and may just be using you for information. he constantly inquires if people want to commit double suicide with him (though if anyone took him up on the offer he would probably flee), uses people for what he needs and can be overtly obnoxious.
he can be touchy with people, flirty, and can get into deep discussions about torture and death. he's been the one dealing some very triggering content in the past. he claims to be a changed man now, but those roots still remain. dazai is a boundary pusher. it's who he is.
if this bothers you please feel free to reach out!! or feel free to entirely opt out of dealing with him, there's never any pressure to tag back..
