This is what I call an overpowered MC in an Isekai manga. MC has a great twisted character that slaughters everyone and I loved watching. It kind of gives eminence of shadow vibes but I would prefer this over that. Can't wait for the next chapters. Story (7) At the start, I was wondering where they were taking use with this weird setup but after 18 chapters I had a blast watching over Maniac MC. Art (5) Actually, I personally didn't like the art for this one.Character (8)
The personality of the MC is the main highlight of this manga. Over MC is a maniac and I loved watching him. Other characters were the same old classic isekai characters.

Enjoyment (8)
The story, art, and the character have an excellent connection so yeah I enjoyed it

Overall (8)
Pretty much this is a great manga, hoping for it to become animated
