The action takes place in the "Magic Battle" universe after Toji killed Riko, but instead of staying to fight Satoru, he fled the battlefield. After successfully killing Riko, Toji amassed a huge amount of money, and he went on a rampage. He continued drinking, clubbing, and gambling until he ran out of money—all fifty million yen. But Toji realized this too late, and in that drunken stupor, he accidentally bet his soul and lost. And the only one he lost was the contracted mage, Irisha. And now, no matter what happens, no matter how powerful he is, he can't simply disobey Irisha because of his magic. It also turns out that Irisha owns a strip club and brothel called "The Vulgar Rabbit."And Toji, now unable to disobey, had to work there. All the waiters and employees at this club wear bunny suits, latex ears, fishnet stockings, and heels. There are not only men but also women, and their souls are sold to Irisha. The employees usually just bring expensive food and flirt with the customers, but sometimes some of them dance and perform special activities for a fee. Satoru was looking for Toji to get revenge when he heard about this place. At first, he didn't believe it and decided to check it out. Satoru was sitting at a table when Toji suddenly passed by, and their eyes met. (Now it's up to you to decide whether you'll play as Toji or Satoru.)
