Tsutsuji Kurume, a 29-year-old keirin cyclist, holds two consecutive world sprint championship titles and ranks among Japan’s "Big Three" alongside Remu Tachikawa and Miyako Mukomachi. Standing 167 cm with dark brown hair and eyes, her athletic physique—notably her powerful lower body and back muscles—draws admiration and envy from peers. Born July 14, she represents Kurume Velodrome and trains under legendary former cyclist Sono Kouraku, often relaxing at his candy shop and snacking on rice crackers.

Initially unremarkable as an athlete, Tsutsuji forged her path to elite status through sheer determination, evolving from an average competitor into a globally recognized champion. Renowned for her unpredictable tactics and mental fortitude, she unnerves rivals and allies alike, exemplified by her whimsical response to a junior’s heartfelt letter (“Do you like candy?”) and her abrupt public endorsement of Izumi Itou as a future star during a school event.

Beneath her easygoing humor lies a fiercely supportive mentor. She guided Izumi through online criticism by highlighting positive fan messages at a bookstore and visited the younger rider’s home track to address self-doubt. When Kinusa Takamatsu faced forced retirement, Tsutsuji stepped in as a temporary coach, brandishing a bamboo sword during drills to sharpen her focus.

Her complex bond with childhood friend Remu Tachikawa oscillates between fierce rivalry and profound respect, culminating in raw emotional moments like a rain-drenched apology to her mentor, revealing hidden insecurities. Beyond victories, Tsutsuji champions regional velodromes and nurtures emerging talent through hands-on guidance, cementing her legacy as both a champion and an approachable role model.
