The most perfect revenge manga i've ever read. Are you sick of revenge manga's where the hero goes crazy but takes his sweet ass time and a million chapters to even kill one of his targets?
NOT THIS BABY THIS IS THE ONE YOU WERE WAITING FOR!
so perfect it will give you the warm fuzzies that you always wanted. Warning - somewhat extreame but very unrealistic gore.
The Hero Who Seeks Revenge Shall Exterminate With Darkness
