Description
Yume Nijino is the female student idol protagonist of the first and second seasons of Aikatsu Stars!, later appearing in Aikatsu on Parade!. She is 14-15 years old, stands 154 cm tall, and has a March 3 birthday (Pisces) with blood type O. Her surname Nijino combines "rainbow" (niji) and "field" (no), while her given name Yume means "dream".
Assisting her parents at their confectionery shop defined her childhood, alongside playing volleyball before enrolling in Four Star Academy. Her entrance performance generated a powerful rainbow aura, enhancing her abilities but causing her to faint. Waking alongside Hime Shiratori in the infirmary marked the discovery of her latent talent.
Physically, Yume possesses fair skin, gradient orange eyes, and long light orangish-yellow hair with pink ombre ends, typically styled in curled pigtails tied with a signature pink ribbon on the left. By Season 2, her hair grows longer and wavier with more prominent pink ombre, her pigtails tied higher. She wears a specialized uniform as an S4 member.
Her personality blends cheerfulness, curiosity, and strong determination with emotional sensitivity—crying easily when touched and flushing red when embarrassed or angry, earning the nickname "Boiled Octopus" from Subaru Yūki. She exhibits boldness and occasional impulsiveness while remaining deeply supportive of friends and unwavering in pursuing goals, refusing to quit and believing admiration fuels further aspiration.
Key relationships shape her journey: Koharu Nanakura is her childhood friend and roommate until Koharu relocates to Italy; Rola Sakuraba becomes her first friend and rival at Four Star Academy; Hime Shiratori serves as her admired senpai who helps her harness her rainbow aura; and Subaru evolves from a teasing acquaintance to a declared rival. She later forms close bonds with S4 peers Mahiru Kasumi, Ako Saotome, and Lily Shirogane, mentoring Aria Futaba at Hime's request.
Her development includes co-founding the fashion brand Rainbow Berry Parfait (originally Berry Parfait) with Koharu, reflecting her desire to "bring out the best and brightest in everyone." She becomes the first non-S4 idol to perform in a Premium Rare Dress and eventually joins S4's 26th and 27th generations, fulfilling her initial dream. She motivates others by stating, "As long as you don’t give up and do your best, you’ll realize your dream."
In Aikatsu on Parade!, Yume appears as an established S4 member when interdimensional doors connect her world with Star Harmony Academy. She interacts with protagonist Raki Kiseki and others during cross-series events, hosting Raki at Four Star Academy, participating in brand showcases for Rainbow Berry Parfait, and performing alongside previous S4 generations. These encounters reinforce her belief that idols should "become the bright light that makes everyone’s hearts shine."
Her hobbies include making sweets and playing volleyball, with koalas and sweets listed as favorite interests. She is the third Aikatsu! protagonist and "The Rainbow Idol," the second main character to change hairstyles mid-series, and the sixth to create her own brand.
