Onda, the moneylender, tells the story of how his ex-friend borrowed money from him and then bailed out. Onda says he's the co-signer of the loan, so he'll pay back the money. He doesn't know why he should have to do this, but he can't figure out how to get the money back. He tells Onda to look into a client named Ryusei Kurokawa, who's rich, famous, and asks him for sex on a regular basis. He's also asking for some dirt on the old man who borrowed the money from Onda. If Onda won't pay him back, he can run away.
