OVA
Description
Nina Wáng hails from Artai, a kingdom without native Otome warriors. Her childhood unfolded in harsh underground communities until a military raid led by Sergay Wáng on September 7th resulted in her adoption. This date became her chosen birthday, coinciding with Princess Mashiro’s birth and her first encounter with Sergay. He gifted her a pocket watch bearing their photo, a token of their bond.
At Garderobe Academy, Nina rose as the top Coral student, fiercely driven to earn Sergay’s approval. She shared quarters with Erstin Ho, who nursed unrequited affection for her, and Arika Yumemiya, whom she initially resented. This jealousy stemmed from Arika’s closeness to Sergay and her possession of the Blue Sky Sapphire—a gem once held by Lena Sayers, Sergay’s former love. Despite clashes, Nina cultivated a complex rivalry and fragile friendship with Arika.
Nina’s concealed heritage revealed her as Windbloom’s true heir. As an infant, she was rescued during an attack by Lena Sayers, who entrusted her with the Blue Sky Sapphire before vanishing. Human traffectors transported her to Artai, where Sergay later saved her. This royal lineage granted her the power to wield the Harmonium, an artifact tied to Windbloom’s bloodline.
During Schwarz’s invasion of Windbloom, witnessing Sergay shield Arika ignited violent jealousy in Nina. This emotional surge activated the corrupted Ultimate Black Diamond gem, forging a contract with Artai’s Nagi. Empowered in her enhanced Meister Robe, she assaulted Arika, but Erstin intercepted the attack, sacrificing her life. Nina’s ensuing duel with Arika unleashed catastrophic devastation. She then served Nagi as his Otome, burdened by guilt over Erstin’s death and unresolved tensions with Arika.
After Windbloom’s liberation, Nina withdrew to a forest cabin with Sergay, who lay comatose from injuries. Upon waking with amnesia, she introduced herself without her childhood moniker "Neena," signaling a shift from their father-daughter dynamic.
In the *Zwei* OVA sequel one year later, Nina lived secluded with Sergay, her hair grown long. Juliet Nao Zhang recruited her to probe ruins in Artai. There, she uncovered the Neptune Emerald Meister gem, which teleported her to the Black Valley. She formed an interim contract with Mashiro Blan de Windbloom, manifesting a teal robe and a bident spear. Her technique "Dash Cold Water Spout" aided in defeating the entity Yuna alongside Arika. Her role as Mashiro’s Otome remained unsettled post-battle.
The manga adaptation diverged sharply: Nina appeared as an orphan unconnected to Sergay or Windbloom royalty. Trained as Nagi’s Otome, she contracted with the imposter Mashiro (Manshiro) after Nagi’s demise, wielding the Black Smoke Chrysoberyl gem. Romantic feelings for Manshiro and her survival past a critical clash were confirmed, though she never faced Erstin’s death or the same rivalry with Arika.
