This is the story of a terrible crime committed against a 17-old-girl, committed, in part, by 17-year-old boys. Why did such a thing happen? Why was no one able to prevent it?

In the beginning, high school boys Hiroki and his friend Takashi are rescued from bullying by a notorious gangster, Miyamoto. At first, they are thrilled to be under his protection, and cheerfully run off anyone who threatens them with the mere mention of Miyamoto's name. Soon, they learn that there is a lot more to being in Miyamoto's gang than just being protected. In return, they're expected to offer loyalty and obedience, or face possibly deadly consequences. This becomes harder as the violence and the crimes they find themselves committing begins to escalate.

One night, they kidnap a high school girl, Sachiko. Now Hiroki has two battles to face. Internally, he faces the dissonance between his sense of self-preservation and his conscience. Externally, Sachiko's twin sister Miki, who goes to Hiroki's high school, her parents and the police are searching for the missing girl. Will Sachiko ever return home? What kind of person--or monster--will Hiroki become?

Reading the reviews here, I realized that this manga was based off of on a true story. After reading the manga, I checked out the real story to see how near to the actual story this manga was and also if the victim was faring well. What I found out was...disturbing. The manga is not even close to the real injustice the victim faced. This, however, does not make the manga bad. In fact, I am glad the manga did not remain true to the actual case because the torture the real victim faced was just horrible. No, it was more than horrible.

This is a manga adaption of a novel interpretation of the real life events of Junko Furuta.

It's hard to say this is enjoyable due to the subject matter, but a good way to describe this is a manga episode of 'Criminal Minds.' The benefit that 17-sai has over virtually every episode of Criminal Minds is that 17-sai wasn't created to capitalize on people's morbid interest in all things evil, but to memorialize an event that should have never taken place. (if 17-sai WAS originally conceived for the sole purpose of making a profit, than damn the original writer, Seiji Fujii)

Morals aside, the actual story follows read more

As of now, there's only one review for this manga. When I first found this, that review almost dissuaded me from reading; honestly, I was scared of what I was about to read. It took me a couple of months before I could actually sit down and read the whole thing, so I will leave you my general impression in order to help people with doubts like me decide whether to read it or not.

To keep it spoiler free, I'll just say that the manga is a lot more "vanilla" compared to the actual crime which you can read about on wikipedia, so unless you're read more

It's hard to talk about this manga, especially when it's based on a real life atrocity: the murder of seventeen year-old Junko Furuta, best known as "forty-four days of hell" or "concrete encased high school girl case." The former refers to the course of time in which she was kidnapped, assaulted, tortured, beaten, mutilated and then murdered. The latter refers to what her captors did with her body afterwards, putting it in a 55-gallon (208 liter) drum and filling it with wet concrete. When it dried, they loaded and eventually disposed the drum into a cement truck in Kōtō, Tokyo. Why was such a horrific read more
