Sakuno Ryuuzaki

As the gentle granddaughter of Seishun Academy’s coach, Sumire Ryuuzaki, this soft-spoken girl is defined by her deep affection for Ryoma Echizen. Though her shy nature and various mishaps often prevent her from confessing her feelings, her devotion remains clear. While the anime portrays her as a comedic novice, the manga reveals her as a talented athlete capable of high rankings. Driven by her admiration for Ryoma, she transitioned from a mere spectator to a dedicated tennis player.
