Description
Shungo Ninomiya is a high school student and formidable martial artist, instinctively defending himself even during sleep. He displays consistent disinterest toward women despite enduring frequent advances and harassment from female classmates, exercising self-restraint through avoidance. Only Mayu Tsukimura and Reika Hōjō hold exceptions to this detachment, sharing deep connections with him.

Physically, Shungo possesses brown spiky hair, brown eyes, and a tall frame. His childhood was marked by neglect after his parents vanished; his mercenary sister Ryōko frequently abandoned him, forcing early self-sufficiency in domestic tasks but depriving him of typical friendships and experiences. A pivotal trauma involving Mayu and Reika fractured their bond, though Shungo largely repressed these memories. Fragmented recollections later resurface, revealing their past closeness—Reika retains vivid recall of their history.

Shungo’s life shifts when Ryōko dispatches Mayu—a succubus with androphobia—and her brother Mikihiro to reside with him. Ryōko mandates extreme proximity between Shungo and Mayu, including shared rooms, baths, and beds, to cure Mayu’s fear of men. Shungo uniquely resists Mayu’s innate succubus abilities, which typically compel uncontrollable male attraction.

Reika, the student council president and heiress, is blackmailed into becoming Shungo’s maid after a failed seduction attempt is recorded. Her presence intensifies tensions, as she nurses jealousy toward Mayu and suppressed feelings for Shungo. Reika intermittently manifests an alternate personality that aggressively pursues him.

Throughout unfolding events, Shungo’s combat prowess surfaces in feats like dislocating his shoulder to escape restraints, leaping from high windows to evade harassment, and blocking blades barehanded. His forgotten past with Mayu and Reika gradually reemerges, exposing how a childhood incident shattered their relationship. This compels Shungo to confront his role in their shared trauma while navigating a volatile love triangle. Critical moments include near-intimate acts to restore Reika’s health and a climactic confrontation where Reika’s alternate personality attempts to claim him—a crisis averted by Mayu’s intervention.
