Description
Aine Yūki is one of the two main protagonists in the Aikatsu Friends! series. Born on July 20, she is 13-14 years old in the first season and 15-16 in the second. Her family runs the Penguin Café, where she works before becoming an idol.
Naturally cheerful and positive, Aine possesses exceptional friendliness and a strong belief in the power of friendship. Her defining catchphrase, "I'll make one million friends!", reflects her goal of forming genuine connections. This leads her to greet strangers openly and prioritize helping friends, though she initially lacks concrete ambitions beyond friendship-building. Her family is extremely important to her; she maintains close bonds with her parents, elder siblings Kazune and Suzune, younger siblings Momone and Yoshitsune, and younger brother Penne. She dislikes crying and specializes in music, interpersonal communication, and small talk.
Aine has vibrant red-orange eyes with yellow flecks. Her distinct hair transitions from cornflower lilac-pink at the roots to a chardonnay-orange ombre at the tips. Her hairstyle evolves: twin pigtails in early years, shoulder-length hair later, a side ponytail at age 11. In Season 1, she has straight-cut bangs with curled forelocks over her shoulders, accessorized with a light turquoise headband and bow. By Season 2, her hair grows longer and curlier, tied partially back with a standalone turquoise bow replacing the headband. Standing 155 cm tall, she shares the title of shortest protagonist with Mio Minato.
Her idol journey begins when she delivers her favorite food, a tomato basil cheese sandwich, to Mio Minato at Star Harmony Academy's idol division. After subsequent interactions, Mio invites Aine to form the Friends unit "Pure Palette," prompting Aine's transfer to the idol division. Aine debuts with a duet rather than a solo performance and wears a Rare coord instead of the typical Normal Coord. Her preferred brand, Sugar Melody, originates after she admires designer Chiharu Hachiya's sketches, inspiring its creation and establishing their designer-muse relationship.
Aine evolves from following Mio's lead to developing competitive drive, acknowledging both Mio and Mirai Asuka as rivals. She emphasizes friendship depth over quantity, stating to Mio: "Even if I had a million friends, I'd still choose you!" She matures by recognizing each friend's unique contribution to her growth. In Season 2, set two years later, she encounters the enigmatic idol Hibiki Tenshō, advancing her journey further.
Franchise distinctions include Aine being the fourth main protagonist, the first with a non-pink/red accessory (her turquoise bow), the first to debut via duet, and the only protagonist without floral motifs in her aura. She performs a Special Appeal in her debut like Ichigo Hoshimiya and Yume Nijino. Her family's food business parallels Ichigo's and Yume's backgrounds. She is the third protagonist to change hairstyles mid-series and the sixth with gradient hair.
Etymologically, her surname Yūki (友希) combines "friend" (友) and "hope" (希), while Aine (あいね) is commonly rendered in kanji as 愛音, meaning "love" and "sound".
