How do you describe this manga? What kind of perverse incentive was at play for someone to write, storyboard, then draw this manga? Who thinks of this kind of thing? These were all questions I held in my mind as I decided to take a peek down the deep dark yawning abyss that is this manga of insanity.

Story: 7/10. It gets the job done, moves at a natural pace, and is generally appropriate. It's fairly predictable, however, every chapter reveals another facet of the torturous mind that must have been slaving away to come up with so many ways for people to die. I'm not sure if you're supposed to keep a level head while reading this story, but I certainly felt like I was being roped down into insanity along with Ayano while reading this manga. Its pacing is quite good; it never slows down or speeds up to an unacceptable rate. The story progresses naturally much like a derailing train would generally stay put for most of the journey before hitting something, and, oh s h i t, now everything's exploding. The ending is sudden, and the pacing is incredibly intense, but yes, it felt natural and appropriate.

Art: 9/10. Now the art is generally controversial. Some like it, some love it, some hate it. I personally enjoyed the art quite a bit. The exaggerated, haunting expressions of some of the victims are burned into your mind, leading to a greater emotional impact. Most of the time, Ayano looks generally pitiable, or downright evil, just as the character tends to be. I liked the art, some disagree, all there is to it.

Character: 5/10. There is no character with a personality in this manga. What's Ayano's personality? Her one trait is she gets bullied. There's no reason, she just gets bullied. Ok. What's her response? Hurt everyone. That's it. That's her character, done. What about Ai? She wants to hurt everyone. ANything else? She's also crazy devoted (and also just plain crazy) to Ayano. Ok. Anything else? Nope! They are just there for the shock value. Oh no, taichou's (student council pres) dead. What was her character? Abused by her parents. Oh no, Ren's stabbed. What was his character? He hurts women and somewhat cares about Ayano. Huh. The reason this story was less satisfying as a revenge drama than it could've been, is because even though those characters do horrible things to Ayano, they themselves are always flat and unappealing, like cardboard. Thus, the emotional satisfaction of watching said cardboard character get tortured is also less than a fully-fledged developed character doing the same. Let's take Nidome no Yuusha for instance. Similar story, set in an isekai. The final torture of the mage in volume 2 has been developed for so long you understand the character intimately. This is a character you absolutely despise, and thus, watching her die, is also satisfying. Let's compare this to said taichou. The only thing you know about her, is she said some mean things to Ayano once. Wasn't even that bad. Then, she is shown being locked up by her parents and promptly kills herself. She's probably the most emotional death (except for those Ai lovers out there) in this manga, and even writing it out feels hollow. The characters are this story's weak point. Without characters we're invested in, every death feels hollow, like a chore.

Enjoyment: 7/10. It was ok. I was looking for a revenge story, it satisfied the itch. Not particularly brilliantly; emotional satisfaction was lessened by the massive cast of students we were literally tearing our way through, but it was ok.

In the end, it's a dark, messed-up story about revenge and murder and psychological damage. This manga messes with your head, and generally just pushes the edge factor so far its left the earth. I think that that's the only way to conclude this review: edgy, messed-up revenge.
