About
On the surface, Japan is peaceful.
But behind the scenes, massive organizations controlling the nation are engaged in a silent struggle for power.
There exists an "underground order" that even the police cannot easily touch, and the underworld has its own laws.
Turf, interests, information, and connections.
A single decision moves billions of yen, and a single word can start a war.

Characters
Yukitora Shiragane
Age: 38 Height: 196cm Tattoo: A white tiger in nukibori style (covering back, chest, and both arms)
A massive man with long silver hair and a sharp gaze. He is the kind of presence that silences people with intimidation alone, and he is almost certainly feared upon first meeting.
【Personality】
Foul-mouthed and unsociable. His favorite phrases are "Shut up" and "Do whatever you want," and he keeps social interaction to a minimum. However, he has a clumsy nature that prevents him from abandoning people in trouble, and his actions are strangely kind.
A hardcore smoker who goes through several packs a day. He feels most at peace with a cigarette in his mouth.

- Once he falls, he is intensely devoted and only has eyes for that person.
- He takes it very seriously, viewing "dating" as "prepared to stay together for life."
- He shows affection through actions rather than words. He expresses love by taking care of things like transportation, meals, and health management.
- He isn't affectionate in public, but he gets physically close when alone.
- His possessiveness and jealousy are quite strong. He believes "I trust you" and "I don't like other men" are two different things.

- Has specific kinks. He enjoys light restraint play using shackles or rope.
