   Summary

   Izuku Midoriya was very busy mentally recovering from the results of his battle with Overhaul when he suddenly found himself isekai'd into another world, only to discover that the same fate happened to Tomura Shigaraki.

   And now they're sharing a single body, and are told to manage a magical Dungeon (a giant death trap for adventurers) together by a definitely insane deity responsible for their appearance in this world. While constantly arguing with each other in their head. Oh, and their mission is to kill a hero, of all people (and only one of them is enjoying the prospect).

   They have been isekai'd against their will and now they're going to make that everyone else's problem.
