Imprisoned by the yakuza, drugged, forced into promiscuous sex, and reduced to a life of depravity, he can only trust and protect his glamorous girlfriend for a week. Aizawa Miyu DASS-576

While we were enjoying happy days with Miyu, one day a group of yakuza members suddenly appeared. They said that Miyu had escaped after being imprisoned and owing money to the yakuza. They tried to take Miyu away, but ended up being kidnapped themselves. The yakuza imprisoned us, saying that if Miyu could endure a week of special training, they would release us both.
