Before writing this review, I sat in my chair for 5 minutes chanting "Oh I have to review this shit pile". That's how much I hate this thing. It wasn't worth reading what there is and I want that time back, it's so awful. It's legit just someone's murder fetish. Note that this review contains spoilers for chapters 20 - 26 and that they're not censored or anything. I'm extremely sorry.

Story: 1
Revenge stories are something I enjoy when you understand why the protagonist wants revenge. I would say spend at least a volume on setting up the awful happenings that lead to revenge. Basically, the more extreme the revenge, the more time should be spent on why they want such terrible things. This manga gives a single chapter and expects us to go along with it. It makes the protagonist look immoral with how little we get to see. I became more invested in a shopkeeper's story and that was only there for what, a page?

Art: 2
It's extremely mediocre, nothing special. For something like this, it makes everything feel slightly off considering how distraught the characters are. Plus, there's too much fanservice. I've read Keijo, and it was really fun. But not this. There are just so many nude and lewd girls that it feels more like cheap hentai than a mind-bending manga that's supposed to make you question everything. I did not need to see a gigantic black spiky dildo.

Characters: 1
The main character is a Gary stu who is perfectly justified in the mass genocide and horrible atrocities he commits against innocent towns. In case he seems like a total villain, don't worry, this manga has the solution of instead of using the protagonist's horrid deeds to compare him to the bad guys and show how he's becoming what he hates and give a relatively interesting comparison, let's just make the bad guys even worse! See the sword hero? She's a rapist now. That makes her horrible cannibalism and rape justified. Fantastic. Plus, his harem is just a sex club.
Don't get me started on the bad guys, they seem bad for the sake of being bad rather than interesting immoral characters. Plus, everyone who doesn't have some positive relationship with the protagonist, his harem, or his village is pure evil unless they're not fully human.

Enjoyment: 1
This was literal torture to read. The disgusting fetishism, the horrid characters, and no elements I was promised. This sucked so much.

Overall: 1
Please do not read this unless you like mindless murder porn. I got so angry I want to create a fantasy world base. And I probably will.
