Carrera, a cunning demon, specializes in crafting soul-binding contracts with unsuspecting humans. Working alongside her competitive partners Mercedes and Rati for the underworld's agenda, she encounters the timid Ogawa and finds herself unexpectedly drawn to him. When Mercedes challenges her interest in the nerdy human, celestial warfare erupts as righteous female angels intervene, armed with divine purification to reclaim Ogawa's soul from the demonic forces.
