Himuro and Tamura, well-known figures in the yakuza world, lead the Yamazaki Family of the Kyowa Clan, Japan's largest yakuza organization. Their meeting dates back to elementary school.

Meanwhile, a shabby-looking transfer student named Tamura appeared. For some reason, Himuro was curious about him.
