[Spoiler](/s "The Bishop of Gluttony, someone who is evil for the lulz, "erases" Rem from the world (as of arc 4 she is still just a corpse), ultimately causing everyone but him and Beatrice to forget of her existence. He then starts to kill himself over again, to try to save her, but the save point has already moved to after he killed  Betelgeuse, so he can no longer save her by "normal" means.")
