I'm going to try to keep this short since I personally don't like two page long reviews myself but here goes.

Story: 7/10
Now this plot isn't the most original out there but where the story excels is in it's unrealistic and captivating way of interpreting it's plot. Every second of it was entertaining and left you wanting more. For now the manga seems like it's merely a thrill ride of craziness (which also has it's own merits) that doesn't portray any meaning of any sort but that could all change as the story progresses.

Art: 8/10
As for the art, it reminded me of Tatsuki Fujimoto's art style (Fire Punch, Chainsaw man...).The art isn't Berserk or Vagabond level but it has it's own charm in my opinion. Now what I really adored were the horror looking panels, those were insanely good and fitting for the story and it's fucked up characters. (Honorable mention: the eyes)

Characters: 6/10
Now the characters are one of this manga's problems. Apart from the main character, none of them are likeable. Literally all the side characters need psychological help including the main female lead but the thing with her is that her mental issue is being so immeasurably stupid. She also seems to be pulling many strings in the manga and could completely change our mc's goals. Aside from that, some actions taken by the characters make 0 sense or are far-fetched but that adds to the "unrealistic and captivating" aspect. The main antagonist (leader of the bullies) seems pretty interesting, she's by far the most fucked up character but her/his (idek) way of thinking is intriguing.

Enjoyment: 9/10
Sometimes I come across that manga that gives me that urge to read the next chapter and this was definitely one of those. I binged it all in one sitting and although the last few chapters felt less good, it was nonetheless an amazing read. The story, the art, the characters.. All of it may seem average if you look at them individually but somehow everything mixed together resulted in a really fun ride.

Overall I'd give it a 7.5 for now.

TL;DR:
Dark, martial arts, torture, rape, psychological shit and a badass mc all into one manga. Worth a read, has some amazing panels, very fucked up characters and chances are you'll love it. Just try out chapter 1.

Well I ended up writing loads but I said what I wanted to say, hope this was helpful.
