Roulette Rider, legally named Satoru, occupies the C-Class Rank 1 position in the Hero Association. His heroic persona revolves around a cycling theme, distinguished by a green helmet covering short brown hair, sports goggles, and complete protective gear. He always employs his signature bicycle for patrols and missions. While off-duty, he dons large round glasses. Satoru’s childhood hero role-playing foreshadowed his commitment to justice. He secured the C-Class top rank six months before the Deep Sea King incident. His moral code prioritizes courage and self-sacrifice, demonstrated when he confronted the Deep Sea King despite knowing victory was unattainable. During that battle, he proclaimed his intent to fight irrespective of outcome, driven solely by endangered civilians nearby. This confrontation caused critical injuries and necessitated Saitama’s rescue. Modesty defines his self-perception; he deems himself unfit for B-Class despite his standing. He treats colleagues like Saitama and Genos with respect, acknowledging their deeds gratefully. After the Paradiser incident, he received public credit for Saitama’s victory but expressed bewilderment over the misattribution. In the Alien Invasion arc, he volunteered for A-City search-and-rescue efforts, successfully evacuating survivors including a reunited child. His inquisitive side emerged when he questioned Garou’s suspicious nighttime behavior in a park, preceding the Tanktop Gang’s arrival. During the Hero Hunt arc, he intercepted an attack meant for Garou during Tanktop Master’s fight, advocating redemption over execution. Garou then brutally hospitalized him. While recovering, he alerted Saitama to Garou’s combat skill and identified the martial arts style connecting Garou to Silver Fang. Later, he discussed Garou with Tanktop Master and Charanko on the hospital rooftop. Recently, he joined the Hero Name Victim Association to challenge assigned hero names. Following the Monster Association’s defeat and Neo Heroes’ emergence, public faith in the Hero Association waned. Amid this turmoil, Roulette Rider persists in patrolling and upholding his duty to safeguard civilians.
