Ruby hails from the prestigious Kurosawa family and attends Uranohoshi Girls' Academy as a first-year student. Naturally reserved and easily startled—often letting out her signature 'Pigi' squeak when surprised—she has harbored a deep love for idols since childhood. Encouraged by her close friend Hanamaru, Ruby gathered the courage to join Aqours, channeling her passion into crafting the group's costumes. Beneath her timid exterior lies an unwavering dedication to the idol world; with each performance, she steadily conquers her fears and reveals a strength that surprises even those closest to her.
