Ken Sudō, a towering Class D student at 183 cm with fiery red hair and a muscular frame, commands an intimidating presence that masks his academic struggles. Raised by a janitor father after his mother’s abandonment, he internalized self-loathing, dubbing himself “born from trash parents,” and channeled his energy into sports while neglecting studies. His basketball talent in middle school secured a recommendation to a elite sports high school, but a violent incident shattered this path, redirecting him to Advanced Nurturing High School. Entering with the school’s lowest academic record, Sudō dozed through lessons, baffled by fundamentals like mathematical constants, and clashed peers with his hotheadedness—traits that cemented his status among the “Three Idiots of D-Class.” A near-expulsion for failing grades and a rigged fight orchestrated by Class C forced a reckoning. Suzune Horikita’s sacrifice of class points and Kiyotaka Ayanokōji’s tactical defense salvaged his standing, sparking a transformative drive. Blushing at Suzune’s name and invoking it earnestly, he pursued academic redemption through her rigorous tutoring, steadily elevating his E+ ratings. Athletically unparalleled, Sudō dominates as the sole first-year regular on the basketball team, boasting A+ physical prowess. Though frustration still flares in competitions, he now apologizes for outbursts and reflects—growth mirrored in repaired peer dynamics. Bonds with Kiyotaka, rooted in mutual respect, and Suzune, blending gratitude and unrequited affection, anchor his maturity. A heartfelt confession during a second-year trip met gentle rejection, yet he persevered, undeterred. Rivalry with the egocentric Rokusuke Kōenji sharpens his competitive edge, while teachers like Kazuma Sakagami acknowledge his strides. By sophomore year, Sudō evolves from liability to pillar of Class D, excelling in sports festivals and group studies. His journey—from volatile outcast to resilient teammate—embodies redemption through grit and mentorship, proving even the roughest edges can be honed into strength.
