Ichi the killer, vol. 1
Reading 'Ichi the Killer' manga. The story is wild, crazy and perverted. The villain is a masochist. The hero is a sadist.There is a trauma behind almost every character and gory violence in every 10th page.
Not for the faint of heart.
P.S: There's been a movie based on the comic which you can check out if interested, but honestly I doubt if it would have as much perversion and gore as the manga.
