1 Childe kin where I kin him because being unable to be understood or belong anywhere completely and be himself truly and yet still loved despite it! He knows he's loved but he also knows it'd be easier if he acted the part he's supposed to at a given time and place.

Ranpo because autism prime and feeling misunderstood and a bad kid even though you don't understand why you're bad (simplification). 007n7 because of guilt and the struggle between returning to old bad habits and getting better because the release, the thrill is so alluring. And then there's Dazai, for roughly the same reasons as Childe somehow? But more isolated from society and just being born inherently strange and different.
