Saki Kodaka, a second-year middle school student from Kanagawa, sports a long brown ponytail fastened with a pink scrunchie on her right side, her deep purple eyes contrasting against a polished school ensemble: a white dress shirt topped by a pink vest and matching bow, paired with a black skirt, beige-yellow socks, and brown shoes.

Once a revered elementary soccer ace, her intense commitment inadvertently alienated teammates, culminating in their gradual departure. The fallout shattered her confidence, pushing her to abandon the sport and fostering a lingering dread of collaborative endeavors.

A pivotal meeting with Hiyori Hayama, the singer-songwriter she idolizes, reshapes her trajectory. Transitioning from ardent fan to trusted ally, Saki convinces Hiyori to enter the Extreme Hearts competition, confronting her own fears of discord head-on. Through this partnership, she reconciles with past regrets, fueling both Hiyori’s musical ambitions and her reignited athletic drive.

Dubbed a “pint-sized powerhouse” for her explosive soccer prowess blending strength and agility, Saki anchors the group RISE by harmonizing Hiyori’s swiftness and Sumika Maehara’s raw power. Her bond with Sumika, a neighbor three years her senior, mirrors sibling rapport—playful yet steadfast.

As she navigates residual insecurities, Saki’s empathy shines in recruiting members like Lise Kohinata, bridging their doubts with her hard-earned resilience. Her surname, meaning “small hawk/falcon,” echoes her tenacity, while her given name, signifying “blossom” and “hope,” mirrors her evolution from fractured idealism to determined collaboration.
