OVA
Description
Umi Ryuuzaki, a 14-year-old from an affluent family, sports striking silver-blue hair, piercing blue eyes, and a tall, model-like frame. Her civilian attire—a blue jacket, white blouse, orange necktie, light blue skirt, black tights, and blue boots—mirrors her privileged upbringing as a wealthy only child doted on by her parents. This sheltered life initially fosters a spoiled, short-tempered demeanor, marked by skepticism and reluctance when thrust into unfamiliar situations—like being summoned to the fantasy realm of Cephiro alongside classmates Hikaru Shidou and Fuu Hououji.

As the Magic Knight of Water, she commands aquatic forces, conjuring spells such as *Water Dragon*, a torrential serpent, *Sapphire Whirlwind* for defense or rescue, and *Icicle Blades*, icy projectiles. Her rapier, forged from Escudo—a material that liquefies under others’ touch—showcases her fencing mastery as school team captain. Her armor evolves from white-and-gold sapphire-lined gear to a sleek black leotard with blue accents and a cape, mirroring her growing power and resolve.

Beneath her sharp tongue and impulsiveness lies fierce loyalty. Initially dismissive of Cephiro’s crisis to return home for a fencing tournament, she gradually prioritizes protecting Hikaru and Fuu over personal ambitions. A pivotal choice to revive her Rune-God Selece by aiding her friends mid-ritual—rejecting power gained through abandonment—marks her transformation from self-centeredness to selfless leadership.

She masks concern with teasing, embodying a tsundere nature. Frequent clashes with the mischievous mascot Mokona contrast her reliance on its guidance. Romantic threads vary: the anime hints at unrequited feelings for the ancient mage Clef, while the manga suggests a budding bond with former foe Ascot. A rivalry with Chizeta’s princesses Tatra and Tarta evolves into mutual respect after combat victories, highlighting her strategic acumen and capacity for reconciliation.

Post-Cephiro, trauma from moral dilemmas leaves her withdrawn in Tokyo. Reuniting with Hikaru and Fuu reignites her resolve to defend Cephiro during its collapse, confronting invaders and dismantling the oppressive Pillar system. Her growth culminates in a balanced approach to conflict—strategic yet retaining a spark of impulsiveness.

Distinctive quirks include a love for spaghetti, aversion to sweets, and off-screen cake-baking hobbies. Her name, “Sea of the Dragon Blossom,” linguistically ties to her water magic and Selece’s draconic form. Cross-universe cameos, like her parents in *Tsubasa: Reservoir Chronicle*, anchor her in a broader narrative tapestry.
