Depicted in character databases as a high school student with blonde hair and grey eyes, Asano Izumi bears a name rich in symbolism: her surname 'Asano' merges the characters for 'morning' (朝) and 'from' (乃), while 'Izumi' translates to 'spring' or 'fountain' (泉). Naturally reserved and cautious, she channels meticulous attention to detail and perfectionism into her koto performances. Valuing tradition deeply, she initially grapples with risk-taking due to a fear of failure. Through relentless practice, she refines her skills and rises to become an indispensable club member. Her journey begins by joining Tokise High School's Koto Club, inspired by admiration for her older sister, a former member. This musical path sparks self-discovery, empowering her to overcome personal hurdles and forge connections through shared artistry.
