Shimauma

Tatsuo, Hide, Satoshi, and Aya collaborated in swindling people out of their money, with a preference for deceiving individuals in search of love through marriage services. They excelled at their craft, that was until they crossed paths with the wrong mark. Their illicit activities were exposed when a “collection agency” violently confronted them.
The perpetrator who captured Satoshi and Hide, followed by Aya and Tatsuo, was a crazed maniac who took pleasure in inflicting torture. Tatsuo may have a chance, as the tormentor recognized him. The abuser was “Akasada,” a former schoolmate whom Tatsuo knew, and who had been bullied. By abducting Tatsuo and Aya, they were unwillingly thrown into Aka’s world.
