hehehe my gf drew it a long time ago for a fic that's taken down now but it's called yesterday is gone, all we have is now.
it's a beast fic where fyodor captures chuuya and makes dazai watch on a phone call fyodor torture him and it's them healing from the aftermath that caused. i'm the (long) process of rewriting it better but yeah! he's from that! i like his white streaks a lot
