The Libertinage of the Heir of the Two Swords

A Japanese truck driver named Ryo Tanaka dies for unknown reasons. His soul reincarnates into Roy Kagayami, the last male descendant of the Kagayami Clan—a lineage dedicated to exorcising curses in a modern world that believes them eradicated. Transferred to a new city and school, Roy moves into a massive apartment building housing over five hundred residents: the epicenter where all remaining curses were born. These entities only afflict women whose sexual frustration makes them vulnerable, turning them into vessels for demons that feed on their repressed desire. As the sole heir, Roy receives two ancestral swords: one physical, forged from sacred steel, and another hidden within his own body—his penis, imbued with the clan's power. To free each possessed woman, he must wield this second weapon in an intimate ritual that soothes her frustration, expels the demon, and allows him to destroy it with the steel blade. Only then can the women live free, and the souls of his ancestors, trapped in a centuries-old war, finally find peace.
