The Yakuza Encyclopedia(2009)

I’m Tetsu Nanbara, a reckless punk who cracked open some old guy’s head and ended up in juvie. When I finally got out, everything had changed. Apparently, my actions had wrecked my family. My uncle, at his wit’s end, begged a yakuza boss he knew to take me in—and just like that, I sorta became a gangster. But man, this world is no joke. You gotta polish the toilets until they shine like mirrors, and you're not even allowed to fight most of the time. Eventually, our legendary "Kashira" (underboss) came back, and I was working hard to become a real "otoko" with true yakuza spirit. But then, a war broke out… and it was all because of one of our seniors.
