Rui Kajiro (UKE/SUB)
A pervert and former mid-level mob boss who now heads up the Kanafuji Syndicate. He's cold, unfeeling, and unreasonably greedy. He's constantly sneering at others for acting like fools who are beneath him. His relationship with Tsubaki is like that of a dog and its owner.
In the past he frequently used his own body as a negotiation tool and slept his way to the top, but now he only has eyes for Tsubaki.
