Narita Taishin is a Uma Musume character known for her sharp and rebellious personality. Standing at 145cm tall, she is notably small in stature, which she uses to her advantage with her explosive speed and last-minute sprint abilities in races. She appears as a close friend and rival to Winning Ticket and Raina Hayahide. Taishin is characterized by her aggressive competitive drive and tendency to lash out when frustrated, stemming from deep psychological scars related to childhood experiences. Despite her tough exterior, she possesses excellent cooking skills. She resides in the Ritto dorm as roommates with Super Creek. Her racing strategy leverages her small size as a significant advantage, particularly in her ability to accelerate explosively in the second half of races.
