A few years ago I read a manga with the following features:

  * The protagonist was a teenage boy, who grew up to an adolescent over the course of the story.
  * He cruelly stabbed both his parents to death when he was young.
  * He got sent to a juvenile detention centre, where he learned karate.
  * When he got out he became a delinquent.
  * Highly psychological and adult manga.

I am really curious as to how it ends, but I just can't remember the manga's
name. Any help would be greatly appreciated.

shamo
Manga about a crazy teenage boy


## [Shamo](https://en.wikipedia.org/wiki/Shamo_%28manga%29)

![](https://i.stack.imgur.com/bHfak.jpg)

Selected synopsis (emphasis by me):

> Ryo Narushima (成嶋 亮 Narushima Ryō?), a talented highschooler who was about
> to enter Tokyo University, the most prestigious university in Japan,
> **killed his parents** before his successful life could begin. [...] The
> **16-year-old** bookworm murderer was convicted and **sent to a
> reformatory** where he was gang raped by other boys. Kenji Kurokawa (黒川健児
> Kurokawa Kenji?), a jailed man who nearly assassinated Japanese Prime
> Minister decades ago, was sent to the reformatory to **teach the youngsters
> karate** every week. [...] Ryo returns to society with the mindset of
> gaining strength so as to survive and never be a victim again.

Of interesting note is that

> This story was inspired by the Kobe child murders of 1997 that a 14-year-old
> "Boy A" ("Shōnen A") killed and decapitated several children.

The plot and settings somehow reminded me of
_[Rainbow](http://myanimelist.net/manga/7482/Rainbow:_Nisha_Rokubou_no_Shichinin)_
, which tells the story of 7 teenage delinquents, their lives in the
reformatory, and their encounters in the real world outside. One of the seven
killed his father (if memory serves), another went searching for his sister,
and yet another learned boxing while in the reformatory, all very similar to
what the protagonist Ryo in Shamo did.
