Historia
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.
