Marriages are Made in Heaven.In the restroom of a bar, Mizuki Akabayashi cracks down on three male drug dealers from selling drugs to two female customers. Akabayashi visits the bedroom of Akane Awakusu, who asks how she can be strong enough to kill someone. However, Akabayashi later has to tell Mikiya Awakusu that Akane wants to learn self-defense at a dojo called the Rakuei Gym. Mikiya informs Akabayashi that the drug dealers are from Raira University, and that their club logo is called Heaven's Slave, signified by their temporary tattoos. Six years ago, Akabayashi, a member of a crime syndicate at the time, was tasked to beat a business owner senseless. However, Akabayashi was attacked by Sayaka Sonohara under Saika's control. After Sayaka slashed Akabayashi's right eye, he overcame the curse by ripping it out and he confessed his feelings of love to her, despite her being married and having Anri as her daughter. The business owner turned out to be Sayaka's husband and Anri's father. Akabayashi and Sayaka decided to leave on friendly terms. In the present, Akabayashi passes by a closed down shop for sale and comes across Anri, asking her if she knows anything about the Dollars. Their conversation is cut short when Seiji arrives. Akabayashi meets with members of his former crime syndicate in an abandoned warehouse, but a Molotov cocktail is thrown inside to trap the members and destroy the warehouse. Five years ago, the boss of the crime syndicate convinced Anri's father to be hooked on drugs and to take out life insurance, which was used to buy the warehouse. Akabayashi allowed the boss to be murdered by a young assassin, whose sister has been in the hospital because of the drugs given to her by the boss.
