That's interesting B214. So Ishibumi is sort of doing the opposite of Dante's Inferno or maybe using a different perspective to the story.

@Anon don't take what I said literally, its just info about the bacckground of Malebranche from mythology, Ishibumi will do (as B214 revealed) a different version of Malebranche for the DXD universe
