Nymph is a First Generation Electronic Warfare Angeloid designated Type Beta. She stands 139 cm tall and weighs 29 kg, with physical measurements of 72-45-68 cm. Her appearance features long blue hair styled in twin pigtails with irregular bangs, ultramarine eyes, and pale skin. She wears a short black-and-white striped dress, elbow-length white gloves, a split-cape with salmon and white coloring, thigh-high boots, and a thick black collar with white outlining. Her non-feathered wings shimmer iridescently in hues from purple to green. Created in Synapse, Nymph initially receives orders to retrieve the Angeloid Ikaros. During her first Earth mission, she attempts to hack Ikaros' systems but accidentally removes her emotional restraints, triggering Ikaros' Uranus Queen mode. After failing, Synapse's master punishes Nymph by forcing her to tear the wings off her pet bird and attaching an explosive collar set to detonate upon another failure. Sent back to Earth, Nymph infiltrates Tomoki Sakurai's household to approach Ikaros. She gradually develops feelings for Tomoki and befriends Ikaros, rejecting her mission. As her collar nears detonation, Synapse dispatches two Harpies who trick Nymph into luring Ikaros into a trap, gravely injuring her. When Nymph resists, the Harpies pin her down and rip off her wings. Tomoki and his allies intervene, destroying her collar and freeing her from Synapse. After defecting, Nymph lives permanently with Tomoki. Her wings regenerate when overwhelming joy floods her during Tomoki's command to survive a battle with the Angeloid Chaos. She requests to imprint on Tomoki as her new master, though embarrassment delays the process. She adopts human habits like snacking on junk food, watching soap operas, and attending school. Despite genius-level intellect in science, music, and arts, she struggles academically due to disinterest. She typically refers to other Angeloids by Greek-letter designations. Nymph displays a complex personality: initially arrogant and dismissive of humans, she grows affectionate yet retains tsundere tendencies. She exhibits a darker side, traumatizing Oregano-class Angeloids with her singing without remorse, and reacts with insecurity to comments about her small bust size. Her fondness for birds persists, and she enjoys candy apples. During the Synapse arc, Nymph re-imprints with Synapse overseer Minos to reactivate her collar's bomb, sacrificing herself to destroy Zeus and Ikaros Melan clones. In her final moments, she reflects that marriage involves one man and one woman, mentally leaving Tomoki to Ikaros. She expresses a desire for Tomoki as her master if given another chance. After Tomoki's wish resurrects her, she lives normally with the group, including Chaos. Nymph appears across all series media: manga from Chapter 9, anime from Season 1 Episode 6, both films, OVAs, and video games like *Heart-Throbbing Summer Vacation* and *Forte: Dreamy Season*. Her name derives from Greek nature spirits.
