Scorpion

The Kin-Kumo Ikka and the Hisui-Sasori Kai have been at war with one another for many years. Osaka belongs to Kazuo, leader of the Hisui-Sasori Kai. He inherited it at a young age when his home was attacked by the Kin-Kumo Ikka. Since then, he has done all he can to thwart the opposing yakuza.

Until he's met with a young man from a nightclub.

Yuzuki had a normal life before he got caught trying to steal money from a club owned by a Yakuza group. Now he has two choices. Trust the Hisui-Sasori Kai, or take his chances on his own in a city that's about to be a war zone.
