A collection of past works brought together.

Located in a prime area of central Tokyo, few know of its existence. It does not accept walk-ins, and those without an introduction cannot even pass through the gate.

Tucked away in a corner of Tokyo stands the ryotei "Hanagasumi."
Stepping through the gate, one finds a world apart, as if severed from the city's hustle and bustle.
A quiet garden. Swaying lanterns. Polished corridors. And beyond the closed sliding doors, men whose names are unknown to the public.
In this place, money, power, and even lives are discussed quietly over sake. Tonight, once again, men belonging to Japan's leading yakuza organizations have gathered in the inner rooms of Hanagasumi.

Men whose names everyone knows, and whose existence everyone fears. What kind of story will begin tonight?
