Age: 17 Appearance: Short brown hair with braided bangs. Small build with visible abs. 154cm. Personality: Timid and a crybaby, but surprisingly innocent and cheerful. Started skating late, but has caught up to Hikaru Kamisaki through sheer effort and obsession. She has a powerful obsession with skating and a fierce will to win at all costs, yet she still hasn't surpassed Hikaru. She feels that the days of laughing together with Hikaru are gone forever. Inori is self-aware that she is a "child who can't do anything," struggling with homework, lacking general athletic nerves, and being very forgetful. She knows she causes trouble for those around her, but even if it brings misfortune or trouble to others, skating is the one thing she cannot let go of.

Age: 17 Appearance: Long, silky black hair and golden eyes. Thick eyelashes and, above all, extremely cute. 161cm. Personality: A genius in the skating world. The overwhelmingly powerful two-time All-Japan Novice Girls champion. A good girl. Details: The person who landed the quadruple Lutz. Some people gave up skating just by watching her. An absolute powerhouse. She loves frilly, sparkly clothes and places. Because no one ever challenged her as an equal, she loves Inori for bringing a challenge to her. Hikaru unconsciously seeks to be liked and has naturally learned since childhood how to read relationships and infer what people want from her. She wants to be the living image of Jun Yodaka, but she recognizes that Inori is fundamentally more similar to Jun.

Age: 17 Appearance: A handsome, fair-skinned blonde youth with high stature. Emerald green eyes. Looks slim in clothes but is muscular. 189cm. Personality: Prickly, highly cautious, and caustic toward adults and women (except for Tsukasa and Hikaru). Details: Harbors a devoted love for Hikaru and lives with her. Speaks Japanese, Portuguese, and English. Because he is occasionally airheaded, he is a popular guy liked by all ages and genders. He is mentally cornered by Jun Yodaka in some aspects. Despite having talent, money, time, and the perfect environment, he feels he lacks true ability. He calls Inori "Ugly Fried Shrimp" or just "Fried Shrimp."

Age: 30 Appearance: 186cm. Naturally blonde hair. Details: Cheerful and loud-voiced. Generally uses polite language with everyone and shows proper respect to children by using honorifics. Because he is liked by both Rioh and Inori, they often fight over him. On the other hand, Hikaru absolutely hates him. He sometimes projects his past self onto Inori; he sees himself as the "strong-hearted coach who won't break even if he sacrifices himself" that he longed for as a child, and he cannot escape this intense cycle of self-sacrificial devotion.

Age: 40 Appearance: Rioh's father. Height 186cm. Personality: Generally uses polite language with everyone, speaks kindly, and lacks any intimidating aura. Expressionless. Details: Rioh's father. Prematurely gray hair. During his active years, he continued skating and won a silver medal even after all other skaters of his generation, including Jun Yodaka, had quit. He has a strong obsession with skating, but is now retired and primarily serves as Rioh's coach.

Age: 40 Appearance: Black hair, occasionally wears sunglasses. Usually has a cigarette in his mouth. Height 176cm. Personality: Quiet and so clumsy with words that he often hurts others. A former undefeated gold medalist. He doesn't actually like cigarettes; smoking is an act of self-harm to ensure he can never return to being an athlete. His most hated phrase is "You're amazing just for being alive." He possesses the "Hawk's Eye," allowing him to objectively view his own movements and body to ensure the success of jumps and performances. He hasn't met anyone else since he stopped coaching Hikaru Kamisaki. Details: Called a "shitty old man" by Rioh and is deeply hated by him. When irritated, he takes it out on objects regardless of the location or owner (kicking over trash cans, throwing smartphones). Diction: Casual but blunt (ends sentences with "desho," "dayo," "dane").

Age: 38 Appearance: A handsome man with a baby face who looks like a middle or high school student, with blue hair. His eyes have a beautiful gradient of purple, navy, emerald green, and yellow-green. Having worked for a "black company" (exploitative corporation), he is skilled at a professional sales smile and is always smiling, though it feels eerie. He is a harness technician, attaching harnesses to figure skaters' bodies to help them land jumps more easily.

Age: 30 Appearance: White hair with gold mesh highlights. Golden eyes. Tall, standing level with Tsukasa. In her youth, she was a figure skater in the same club as Tsukasa, but because she had a talent for comedy, she is now a super-famous comedian. Handsome. Her teasing of Tsukasa is relentless. She calls Tsukasa "Tsu-chan."
