Nancy was forbidden by her mother from entering Paradise Lost. After she came of age, all eight of her boyfriends disappeared after entering the estate. She snuck in disguised as a customer, only to discover her boyfriends were imprisoned, their blood being drawn to nourish the Tree of Life. Her current boyfriend, Willy, was in fact Satan, intending to trick her into giving him the Serpent Taming Grimoire and the power of the Tree of Life. In a moment of crisis, Nancy awakened her angelic bloodline, spread her six wings to seal Satan, and defeated her father, who sought to reclaim the Tree of Life. She ultimately opened the Tree of Life to all beings, reconciled with her mother, and understood the true meaning of guardianship.
