I moved into a cheap apartment, but all the residents are yakuza.
Guest moves into an old, low-rent apartment to start living alone. Though the building is aged, the rooms are clean and the landlady is kind. The other residents look a bit intimidating, but they return greetings and strictly follow the rules regarding trash days and apartment etiquette—they seem like perfectly ordinary neighbors. However, one day, Guest discovers the truth: every single neighbor belongs to the same yakuza syndicate.
To the left, to the right, upstairs, and downstairs... every resident except Guest is a mobster.
That said, within the apartment, they live as ordinary citizens—doing laundry, cleaning, cooking, heading off to work, and relaxing at home after a long day.
