Komaba Ikenoue, also known as Komaba Ikenokami, is the focal point of Takao Asagaya's romantic and sexual obsession, characterized by her distinctive purple hair. She occupies a central narrative position without expressing personal agency or perspective. Her background, including family, history, and prior relationships, remains undisclosed.

Komaba becomes an unwilling participant when Takao employs an experimental device to transfer his consciousness into her body. This possession grants him complete control over her physical form. Takao manipulates her body to enact personal fantasies, engaging in intimate encounters with his childhood friend Nakano and performing solitary acts of gratification.

A scene present in some releases depicts Komaba's stepbrother and his associates sexually assaulting her body while it remains under Takao's control, following an escalation of Takao's misuse. Komaba's own will or consent during this violation is not portrayed.

After the consciousness-transfer device is destroyed, Takao returns to his original body, ending the possession. The narrative does not address Komaba's experiences, reactions, or any consequences she faces following these events. Lacking development, motivations, or resolution, Komaba functions primarily as a vessel for the protagonist's actions and the story's themes of violation. Her role sees no further expansion in documented media.
