Wataru Sajō sports black hair, later darkened to brown, with left-swept bangs and striking purple eyes. Classmates deem his looks unremarkable, scoring him a “49” on a scale where average reigns. Once, he adopted flashy styles to catch Aika Natsukawa’s eye, only to realize the look clashed with his features.

In middle school, he fixated on Aika, confessing relentlessly despite repeated rejections. Determined, he followed her to Kōetsu High. A near-collision with a soccer ball during his pursuit jolted him into self-reflection. Abandoning his overt advances, he embraced restraint, leaving Aika unsettled by his newfound aloofness.

Academically, he ranked among the top thirty first-year students before slipping below sixty as self-doubt clouded his focus. Secret part-time jobs from middle school—funding grand gestures for Aika—sharpened his management, teaching, and customer service skills, later leveraged during school festivals. Unexpected computer expertise further baffled peers.

His relationships weave complexity: a submissive bond with his sister Kaede, who pushes him toward student council duties; a shifting dynamic with Aika, now puzzled by his withdrawal as her own feelings stir; playful ribbing from classmate Kei Ashida; and growing reliance from peers like Mina Ichinose and Rin Shinomiya, who trust his problem-solving grit. Ties with Fuuka Sasaki and Yuyu Inatomi underscore his expanding social sphere.

Through school events, part-time hurdles, and crises like a health scare mid-festival, Wataru navigates challenges with pragmatic resolve. Though distancing himself from past obsessions, flickers of care for Aika surface, even as new bonds form. His history of unrequited passion and relentless self-improvement fuels a duality—avoiding the spotlight yet stepping forward decisively to aid others.
