Need help remembering a doujin
Only things I can remember from it are:
Guy cursed or whatever so nobody notices he's there or exists.
He takes advantage of it by having his way with everyone he meets. Sorta like they're not aware someone is messing with them and they carry on with their conversations and what not.
Thanks in advance.
If it helps some entity (Like a demon or something) cursed him for some reason so people would never notice him again. So he went out raping people even when they were having a conversation. But as he was raping them they would act like nothing is going on.
