Story is very solid so far. Good quality, good grammar as far as I can tell, and an interesting plot. +the tatsuro yamashita references are great as well :P

He's an idiot indeed

Plot is straight forward, but the writing quality if hands down horrendous. I've read up till chap 25 and I can't keep on reading anymore as the grammar is non-existent, and the "my dears" in every sentence the MC says that it becomes sickening. In addition to this, the plot does not really have much going on for it. It is a good idea - overlord x marvel, but they guy is literally moving on from A - B with nothing really going on. It's just a OP dude who is getting a Harem. Although I said all this, don't let it stop you from reading this FF, that is if u can handle the grammatical errors.

nah
