This isn't your typical manga where the OP MC battles new enemies and ventures off to save the world. The MC's just trying to live a normal life with OP powers, and it's incredibly entertaining. The dude's so dense about how overpowered he is and the way everyone is shocked by how OP he is makes it funny.
Of course, it might be a little boring and slow to pick up at the beginning, but once the secretary arrives, that's when everything becomes funny. It's honestly a nice break from reading mangas filled with dramatic battles from the beginning to the end. You get your dose of satisfaction from the awesome battle scenes and the reactions he gets from being OP. I definitely recommend this!
