In Shinjuku Kabuki-Cho, 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.

Koroshiya 1, or Ichi the Killer as I will address the serie from now on, is the story of a group of excommunicated Yakuza members who try to achieve money and pursue their objectives by manipulating and killing other criminals, aided by their partner Ichi, a ruthless killer. Ichi is in fact a young man in his twenties, with a dramatic past which caused his mental instability. This manga is his story as well. The author tackles themes such as violence, power, crime and the likes, adds a whole bunch of extreme violence, vices and perversions and builds a complex story which continuosly surprises read more

Okay first things first, having read through Ichi the Killer I feel obligated to say - nay warn - you that this series does NOT pull any punches. The imagery used is both graphic and perverse, many of the characters possess varying degrees of sadism/masochism and the implications that are brought up are quite disturbing all in all.

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 read more

Ichi the Killer is a Seinen, Psychological, Thriller about a twisted yakuza warfare involving psychological mind games. The story itself is about excommunicated gangsters seeking revenge however this isn’t made clear until later on in the manga.

For the most part the story follows a fearsome killer known by his codename (Ichi) and the orders he undertakes from his so-called uncle. The main story may lack some depth but it tries to add some by revealing the past bullying experiences of Ichi, which led to his current state of mind. Although it doesn’t seem to do a good job at relating it to the present, it read more

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, read more

Manga: Gunmania
Both are extremely similar. Both involve a complete psychopath carrying out senseless murders. If you liked one, try out the other.

Manga: Shigurui
As far as graphic violence in Japanese graphic novels go, these two are in the top-tier. Ichi has a modern setting and far more sexual content/rape, but Shigurui's ALMOST as fun to read as Ichi when it comes to OTT violence; body parts flying everything as both fists and swords kill everything. You could describe Shigurui as Ichi's samurai equivalent since the main draw of both is seeing people get brutally murdered and, strangely, enjoying it.

Main characters who are seemingly nice, shy and ordinary people, but in reality they're deranged sadistic killers out on a quest for revenge against those who tortured them in school.

Manga: Berserk
They're both incredibly violent involve lots of adult situations and lots of morally wrong actions.

Manga: Shamo
both protagonist are super strong martial artists and they live in a work full of sorrow and pain.. the underworld, where yakuza and other clans find their place. Both of the character show no mercy when they fight and even kill their opponent.

Manga: Garden
If you, say, don't get nightmares from reading Ichi the killer, or you read it to get those nightmares, I'd say Usamaru Furuyas Garden might be straight up your street. Garden also gives out a certain indie vibe to it that might excuse the excessive indulgence of sex and violence.
