Overall: 8/10

It's a fantastic mindless revenge manga. It has no depth or meaningful story or anything, but that's fine. If you're going to like this, it's probably not for those reasons anyway.There's lots of revenge and it's highly satisfying. No neckbeard BS either.

Character: 6.5/10

The hero is a nutcase and both he and the author know it. The villains are ridiculously evil to the point where you feel they actually deserve what's coming to them (which would otherwise be incredibly excessive). It's very satisfying to watch him f*ck them up in messed up ways. Not exactly the height of good writing, but quite fun.

Enjoyment: 9/10

I like revenge mangas so this is very fun to read. Don't read it if you're not into seeing people tortured creatively; if that's the case, there is not much in this series for you.

Art: 9/10

The art is really good. The artist nails the "unhinged" look, which is important, and the art is clean and smooth. The protagonist looks amazing.

Story: 6.5/10

Not much story here except revenge and more revenge. It's like for each arc, the author thought of something edgy, and then thought of a way to make it edgier, and kept on doing that until they had an extremely edgy setup. I'll give points for sheer creativity in edge, but it's got practically nothing else. Still, it avoids being boring or annoying in any way, which is respectable.
