Interesting fact: the Marvel superheroine Valkyrie is canonically bisexual.
Kageko's version seems to mix aspects of Punisher and Hawkeye (in his Ronin persona), though neither of those "heal others with their smiles". Kageko is a confirmed Punisher fan, having a rug in her room with his death's head emblem.
Feel like a better example of a pushy/mean/realistic/whatever you wanna call it editor is Toudou from "Still Sick," never really felt this guy wanted to help Tadokoro, I maaayyy need to re-read those chapters again tho, been awhile.
Scummy and realistic aren't really contradictions, so I don't know whether that's even worth discussions. He is a piece of crap and, okay, such people exist.
