OVA
Description
Shouji, a moving company employee, was drugged at a dinner party hosted by an acquaintance named Yuka. During the event, multiple women subjected him to repeated non-consensual sexual acts. He lost consciousness and awoke inside a sealed cardboard box placed on active railroad tracks, finding a forged suicide note beside him. He narrowly escaped before an oncoming train destroyed the box. This trauma left him psychologically scarred and consumed by a desire for retribution against every woman involved in his assault and attempted murder. Initially, Yuka was the only perpetrator he could identify.

Using his occupation for inconspicuous access, Shouji arrived at Yuka's residence disguised as a delivery person. He overpowered her, confined her within a box, and transported her to a concealed location. There, he coerced her cooperation in identifying and contacting the other assailants. Yuka complied, gathering explicit photographs and personal information about the group for Shouji to use as leverage. His methodology involved forcibly confining captives in boxes, moving them to his hideout, and subjecting them to sexual violation and planned humiliation as retribution.

His first identified target beyond Yuka was Nanami, a model engaged in sex work as a groupie and call girl. Next, he targeted Maria, an executive assistant characterized by a condom fetish and a preference for younger male partners. Shouji enforced degrading sexual acts upon them after capture. He then pursued Satsuki Saijyo, a scientist with masochistic tendencies and a specific interest in bondage and whip-based acts. His ultimate objective was Ayame Tokudaiji, president of Tokudaiji Pharmaceuticals. For Satsuki, his retribution culminated in public humiliation; he displayed her bound within a box in a populated area while adorned with explicit paraphernalia.

Throughout his pursuit, Shouji maintained Yuka's coerced assistance to systematically locate and subdue each woman. His approach evolved from initial confinement and private violation to implementing psychologically damaging public exposure for his final targets. His actions were driven solely by the trauma of his victimization and the determination to inflict equivalent suffering.
