In Shinjuku Kabukichou, the biggest sin town in Japan, there are two crazy guys. Ichi is a coward and a wimp, but once he breaks into tears, he turns into a human weapon. With great martial arts skill and a blade hidden in his boots, he butchers a bunch of enemies into mincemeat in the blink of an eye. His arch enemy is Kakihara, a yakuza boss who's tired of everything, including himself. Only when he pierces, cuts, and burns his own and other people's bodies does he feel that he is alive.


In 2001, Koroshiya 1 was adapted into a live-action film which was directed by Takashi Miike.

The series has been published in Spanish as Ichi the Killer by ECC Comics since February 20, 2015.

Now with all of this said it's important to note that it is because of these aspects that the story works; because Ichi the Killer does not filter content it can show the darkest part of the criminal underbelly in the least flattering light possible, a light a ...

Wow, this manga will leave a lasting impression on you for a few days after reading it. The art in this book is incredibly detailed (Gekiga style), there are no cutting corners when drawing the characters or even the background scenery. The characters all have their own distinct personalities and they develop more and more as the story progresses. The art also gets better every volume.

This book is enjoyable, if you know what your going to be dealing with. I recommend watching the movie first just to see what your going to be reading. The amount of violence, sexual taboos, ...
