Irori Okushiro, a high school classmate of the protagonist, sports long green hair and glasses, often engaging in playful flirtations with male peers. Introduced as a romantic rival, her succubus traits emerge through energy-draining abilities activated by physical contact, notably demonstrated when she kisses the protagonist during a class trip, leaving him briefly weakened.

This act serves a calculated purpose: to incite jealousy in Tasuku Okushiro, a fellow student entangled in unresolved tensions with the protagonist. Irori strategically leverages public affection toward the protagonist to provoke Tasuku’s emotions, driven by their mutual romantic interest. Her actions reflect a pragmatic focus on nurturing her genuine connection with Tasuku over casual interactions.

Though initially cast in an adversarial role, her arc transitions toward resolution. She openly acknowledges her succubus identity and the deliberate intent behind her earlier behavior, fostering clarity. Her bond with Tasuku matures into a recognized partnership, steering her away from the narrative’s central romantic entanglements.

No additional details about her background beyond her succubus heritage or expanded development in supplementary media are provided.
