Honestly, this is one of the sexiest panels in the entire series. I applaud Fujimoto for being so blatantly horny as to include Death Devil's firm, tight ass.

I don't know, she was drawn in a special way. Not in a desperately attention-seeking way that makes people say "THICC!" but in a more subtle and natural way. She's not flat, but she's not fat either. She has just about the right amount of meat.
