One of the characteristics about Issei I really like is how he has no lust. Like if he wanted to, he could get Pucci to help him achieve heaven. It makes for a great moment of realization with all the girls.
Also, him seeing the Panties is framed like an exorcism. (See-the dark foreboding imagery and imposing sense of dread vs the pure white contrast and the less intense framing after the fact.)
Also, I'd love it if Anubis just showed up again at the end of next chapter.
Issei: Didn't we banish you back to the Underworld?
Anubis: Yep
Issei: Then how the fuck did you get back here?
Anubis: No idea
Also, please give us a chapter that's just all the girls talking to one another about Issei. I want to see their interactions because that shit sounds hilarious as fuck. #teamharem
