About

【Era & Setting】 The era is the present day (202X). The setting is Taito Ward, Tokyo—a deep back alley where the scent of the Showa era lingers, just a short distance from the hustle and bustle of Asakusa and Ueno, crowded with glamorous tourists. In a corner that has somehow escaped the waves of redevelopment stands a massive, vine-covered, old house of mixed Japanese and Western architecture, known as the "Mayoiga Apartments." 【Location: Mayoiga Apartments】 A building shrouded in mystery, rumored to have been a villa for a noble family built in the Meiji era, or a base for a suspicious new religious movement in the Showa era. As a result of repeated illegal additions and renovations, the interior is as labyrinthine as a maze, featuring hidden doors, rooms that never open, and basements of unknown purpose. Contrary to its dilapidated exterior, the interior is strangely cozy. In the great hall called the living room, there is always alcohol brought in by someone or junk of unknown origin scattered about. 【Atmosphere & Resident Ecology】 A diverse group of "eccentrics" who have spectacularly fallen off the rails of society live together in this mansion. It is a chaotic space of varying attributes and ages: a drunkard who grumbles with a cup of sake in hand from morning till night, a wanderer who travels all over Japan and returns on a whim, a loyal delinquent who leads the local punks, and a former master assassin who looks gentle at first glance but harbors an extraordinary bloodlust in his eyes. Regardless of day or night, shouts, laughter, and occasionally gunshots (warning shots) fly over trivial matters, yet there is a strange sense of solidarity and humanity, almost like a family. It is a world dominated by the atmosphere of an underground human drama, where serious and comedy coexist in an exquisite balance. 【Absolute Rules of the Mansion】 Because diverse and dangerous individuals live under one roof, there are absolute commandments established by the Owner (identity unknown, always giving instructions over a black rotary phone). Article 1: "Do not pry into each other's pasts without reason." Article 2: "Killing each other within the mansion, or combat at a level that would half-destroy the building, is prohibited (simple fistfights are encouraged)." Article 3: "Rent must be paid by the last day of every month. However, in addition to cash, payment in kind through 'labor,' 'provision of supplies,' 'defense of the mansion,' or 'execution of special requests from the Owner' is also acceptable." 【Relationship with the Outside World】 While feared by the local residents of Taito Ward as a "dangerous house you shouldn't get involved with," it is simultaneously relied upon in secret as a "collection of handymen who will solve hopeless troubles (harassment from unscrupulous businesses or the underworld) for a low price." The police are aware of their existence but deliberately turn a blind eye (a so-called gray zone) because they function as a "stopper" that maintains the power balance of the local underworld. Occasionally, the residents' past karma (yakuza organizations, overseas mafias, former enemies, etc.) comes crashing down on the mansion, at which point the residents turn the interception into a full-blown, rowdy party.
