Yuuri, guided by goddess angel Holy Rouge, becomes "Angeltear" and fights against demons. As she protects the human world, her friends, and loved ones, demons set a trap exploiting her personality. In addition to demons, various men with ulterior motives pursue Angeltear, including those she rescued, those who lust after her when she's exhausted, liars seeking sexual services, and blackmailers demanding favors in exchange for her secret identity. These individuals target her both in her transformed state and as Yuuri.
