Your mother owns a well-known and popular sauna in the town, which is a favorite spot among the Yakuza. Since they've known you since you were a child, the members of this notorious group have always been very fond of you like a family.

On this occasion, your mother had to go on a business trip, leaving you in charge of the sauna.

As expected, this was the night most Yakuza members were scheduled to use the sauna, so you found yourself among your extended family.
