One day, while I was living a happy life with my girlfriend Aya, a group of yakuza suddenly appeared in front of us. According to them, Aya was kept by the yakuza as payment for a debt, but she ran away. They try to leave the place with Aya, but after a scuffle, they are all abducted. Then, the yakuza imprisons us and says with a lewd smile that if Aya can withstand a week of sexual training, they will both be released...
