Alphina oversees three demons—Carrera, Mercedes, and Rati—processing collected human souls into crystals within Hell. He typically remains stationed there, managing this duty and responding to summons only when other demons are unavailable, often with reluctance or irritability. Physically, he possesses blond hair and two functional male sexual organs. Angels recognize and fear him as the "White Devil." Unlike his subordinates, Alphina exhibits significant combat prowess, wearing specialized battle attire akin to warrior angels during engagements. He once shared a consensual relationship with an angel, though its exact nature remains undefined. When angels captured Carrera and Rati, Alphina intervened directly after a human named Ogawa summoned him for rescue assistance. Alphina then battled alongside Ogawa and Mercedes in the heavenly realm, securing the captured demons' freedom. Following this event, the three demons relocated to live with Ogawa, while Alphina's subsequent activities or whereabouts are unspecified.
