This is one of the best manga i´ve read in awhile,you get really hooked by the first chapter. Honestly it makes you hate the ¨bullies¨of the story pretty early on, I would even say the word ¨bullies¨ too kind of a word to describe these antagonists, these people are psychopaths. The story surrounds the main character who's out for revenge and does it in the most savage and morid way possible. The pacing of the story feels really smooth, and the character design is good too.
Art style is pretty good and follows the dark setting of the story.
(The way the main character looks kind of reminds me of Sasuke, the early on type of animation with the spiky hair and the dead looking eyes.)
10/10 would recommend!
