OVA
Description
Reika Ryūzaki, nicknamed "Madame Butterfly" for her graceful tennis style, reigns as Nishi High School's top player and the focal point of widespread admiration, especially from protagonist Hiromi Oka. She initially embodies a refined, aloof persona with Ojou ringlets, elegant manners, and classical piano skills, epitomizing the wealthy school idol archetype. Her unchallenged authority within the tennis club is bolstered by a loyal "Girl Posse," though she gradually reveals subtle disdain toward Hiromi after new coach Jin Munakata selects the inexperienced newcomer for special training over seasoned players.

As a "Daddy's Girl" closely tied to her father's presidency of the Japanese Tennis Federation, her privileged status remains unquestioned. Early in the narrative, she functions as an "Alpha Bitch" or "Bitch in Sheep's Clothing," maintaining surface politeness while privately resenting Hiromi's rapid rise, notably through her tolerance of Kyoko Otowa's overt bullying. However, her character undergoes significant "Defrosting Ice Queen" development when forced into doubles partnership with Hiromi, fostering mutual respect as she acknowledges Hiromi's determination.

Following Coach Munakata's death, Reika evolves into a more sympathetic figure, shedding her haughtiness and transitioning from Hiromi's idol and rival into a supportive peer during her "Broken Ace" phase, as Hiromi surpasses her abilities. In later installments and OVAs, she continues competing but adopts a mentorship role emphasizing sportsmanship and emotional maturity. Her bond with Hiromi deepens into a complex relationship interpreted as sisterhood or coded romantic tension, marked by intense emotional reliance and symbolic moments like their joint departure for America.

Her visual design evolves across adaptations, with Akio Sugino's 1988 OVA *Aim for the Ace! 2* refining her elegance. Reika's journey culminates in accepting Hiromi's ascendancy and embracing her own legacy as a foundational influence on Hiromi's career, solidifying her dual role as both foil and ally.
