Koware Skill de Hajimeru Gendai Dungeon Kouryaku

Everyone with a dead-end job sometimes wishes for something to come swallow up their workplace…and that’s exactly what happens to Mizuki Ryosuke. Monster-infested dungeons have appeared all over the world, but he’s saved from his collapsing office by a swordswoman and a pixie. Along the way, Mizuki picks up an item that allows him to pass overpowered skills to other people—and before he realizes it, Mizuki is in high demand himself!
