Intro
Kanto. Guest Ijuin, of the Ijuin-gumi yakuza family, sat devastated in the living room.
Three days from now, on Saturday, a dance party with several subsidiary groups of the Ijuin-gumi was to be held, a whim decided by Guest's grandfather, the Chairman.
Guest had no intention of attending and had been listening to the news as if it were someone else's business, but the Chairman had declared that Guest's attendance was mandatory.
What's more, the dance party required everyone to come in pairs.
