What is this wholesomeness in my dungeon sex manga?
But yea, very interesting. They've been throwing hints at it for a while, but Blum's definitely got some PTSD going on. Not from the fight but from the fact that there a bunch of ungrateful assholes out there who somehow think either God or the Devil. For a smut, it's a bleakingly realistic portrayal of how some would treat a "super hero".
Also poor Mary and Shion. Wasn't expecting this Manga to give time to acknowledge the psychological trauma of the whole dungeon rape.
