This is for the person who loves anti-heroes and seeing a character actually go through with their revenge.

Too often are stories of revenge filled with moral dilemma and often the lesson of the story is to not take revenge.

This is not that, this is for the person who likes their heroes dark, the person who wants to see the villain pay for their sins and THEN SOME. This is for the person who wants a main character who could be the villain or the hero. Not afraid to kill, not afraid to cross a line, and will do it in unforgettable ways.

I wouldn't recommend it for someone who just reads shounen you'd probably wanna break into the darker side of action manga with something else like berserk.

Not that you can't enjoy shounen and enjoy this, This is the 2nd manga i've given a 10/10 score in like 10+ years of reading and 100+ mangas. and the first one was/is one piece which is almost like an ultra-shounen

I'm not a fool, when i read it and scored it there were only 12 or so chapters out, with time this score could easily change as the story develops, and i don't rate it a 10 because i think it is 100% perfect flawless in all ways i rate it a 10 because the amount of enjoyment i got reading just 10 or so chapters left a huge impression.
