Nanael is a celestial guardian angel dispatched to Earth on probationary status for recurrent heavenly misconduct. Tasked by the Head Angel to impose "true order," she interprets this as establishing angelic rule over human men while exiling all women. Her trial requires safeguarding a waist-mounted vial of holy milk; spilling it risks hellish banishment. Physically, she has light blue hair, green eyes, and asymmetrical wings that cause profound insecurity. Her attire includes a white camisole, skirt, polka-dotted panties, and steel-plated leggings. Personality-wise, she projects cheerfulness and friendliness but harbors deep arrogance toward earthly beings, exploiting kindness for personal gain—exemplified by freeloading at Melpha’s residence. In combat, she telekinetically controls her Celestial Sabre, specializing in long-range assaults but wielding potent close-range techniques like the Falling Star Kick. Her power fluctuates with the holy milk volume in her vial. Non-canonical *Vanquished Queens* spinoffs depict her defeat by the Swamp Witch in volume one. Volume two shows her "corrupted" state defeating priestess Melpha, likely stemming from failing to protect the holy milk. Volume three references her role in Melpha’s "Tentacles Game" scenario, cementing her antagonism in Melpha’s downfall. Post-tournament during *Rebellion*, Nanael achieves Archangel promotion despite spilling the milk, credited to "bonding" with Melpha—primarily through freeloading. Her arrogance intensifies with this rank. She adopts larger hair clips and winged boots, wielding a new Celestial Sword. Her broader narrative includes aspirations for a male harem and fierce protectiveness toward Leina Vance, though she grows agitated by Leina’s closeness to women like Risty and Claudette.
