Nanael is a guardian angel dispatched from Heaven to oversee and compete in the Queen's Blade tournament, proclaiming a mission to establish true order. Her true status, however, is that of an angelic dropout exiled to Earth by the head archangel as punishment for persistent misconduct and failures. This exile carries a critical condition: she must never spill a single drop of the "Holy Milk" within the vial secured at her hip. Spilling the milk proportionally weakens her powers and risks her immediate banishment to Hell. She defines her mission as creating an angelic society served by enslaved human men, with all women banished. Physically, Nanael possesses light blue hair cut short at her ears and green eyes, standing approximately 162 cm tall. Her most noticeable feature is a pair of asymmetrically sized wings, a source of deep insecurity that provokes intense rage if mentioned. Her attire is a standard lower-ranking angel uniform: a white camisole, skirt, polka-dotted panties, steel plate leggings, and a steel gauntlet on her right arm. In her Unlimited incarnation, her height reduces to 150 cm, her hair clips enlarge, and she gains wings on her boots. She wields a celestial sabre telekinetically as her primary weapon. Nanael maintains a superficially cheerful and friendly facade but exhibits manipulative tendencies, readily exploiting others' kindness for personal advantage, such as freeloading off the holy woman Melpha. She holds profound contempt for humans, whom she derogatorily calls "monkeys" or "lowly beings," refusing to treat them as equals as per angelic doctrine, though she secretly desires a personal harem of human men. She displays intense reactions to interpersonal dynamics between women, showing protectiveness toward Leina Vance and agitation over Leina's closeness with Risty. Frequent clumsiness, especially concerning the holy milk vial, often undermines her endeavors. Despite her behavioral flaws, Nanael possesses significant combat capabilities. Her telekinetic control of the celestial sabre enables effective long-range attacks, complemented by potent close-range techniques like the Falling Star Kick. Flight grants her tactical advantages, including height-based attack modifiers and evasion. In the Rebellion storyline, after deliberately spilling her holy milk, she achieves promotion to Archangel due to her unconventional bond with Melpha, amplifying her arrogance. Her powers encompass light-based attacks and status-altering abilities, such as inflicting "In Love" on male foes or "Penance" on females, as demonstrated in the Rakenzarn spin-off. Her story unfolds across continuities. Initially, she views the Queen's Blade tournament as an opportunity to recruit male servants, expressing disappointment when men prioritize female warriors. During Rebellion, her spilled milk leads to unexpected validation through Melpha's support, resulting in her promotion and heightened hubris. In Unlimited, she serves as a referee angel for the tournament. In the Rakenzarn Tales spin-off, she joins Kyros' brigade after a side quest, pursuing men like Kanon while maintaining her trademark disdain for women. Her combat role there emphasizes high attack power offset by vulnerability to dark-elemental attacks. Nanael's character draws inspiration from Hebrew lore, where her namesake is the 53rd guardian angel associated with philosophy and abstract sciences. Her depiction incorporates pop culture references, with her Falling Star Kick resembling attacks from *Neon Genesis Evangelion* or *Tengen Toppa Gurren Lagann*, and her Holy Dive attack echoing *Gundam* series mechanics. These elements persist throughout her appearances.
