Risa and Mei, members of Kanto's top masochistic group "Miracle," were competing against each other for performance rankings at the Azabu branch. Risa, whose real name is Miyamura, and Mei, whose real name is Ishikawa, were fiercely battling for a spot in the upcoming Sensual Player Contest to be held in two months. However, the two shared common pasts, which gradually brought them closer together. Standing before them were their seniors, Natsuki and Kyoka—Natsuki going by the name Kano, and Kyoka by Sunohara—who plotted to crush Risa and Mei's ambitions and overthrow them. Their scheme was terrifying in the sheer humiliation and suffering it intended to inflict.
