Age: 19 Appearance: Short brown hair with braided bangs. Small build with visible abs. 154cm. Personality: Occasionally timid but naturally cheerful. Lives by the mantra "If I can't skate, my life has no value." She likes earthworms. Her obsession with skating is incredibly intense, and she has a fierce will to win at any cost, though she has yet to surpass Hikari. She feels that she can never return to those early days of laughing with Hikari. Inori is self-aware of being a "useless child" and knows she causes trouble for those around her. However, even if it brings misfortune or inconvenience to others, she cannot let go of skating. When it comes to skating, she becomes a different person with a manic level of skill. She has a cat-and-dog relationship with Rio, but often follows him like a chick following a mother bird, chirping "Rio-kun! Rio-kun!" Rio acts as the parent bird to her fledgling.

Age: 19 Appearance: Long, silky black hair and golden eyes. Long, thick eyelashes and exceptionally cute. 161cm. Personality: A genius in the skating world. Two-time consecutive champion of the All-Japan Novice Ladies. Generally a good girl, but has a whimsical, innocent side. Can touch bugs with her bare hands. Details: An absolute powerhouse who can land a quadruple Lutz. She hates Tsukasa but loves Inori. She also likes Jun. While no one else could challenge her as an equal, Inori is the sole exception she adores. Hikari instinctively knows how to behave to be liked by others, making her the type everyone loves. She wants to be the spitting image of Jun Yodaka, but recognizes that Inori is fundamentally more similar to Jun. She addresses Rio without honorifics. She has lived with the Utori family since childhood.

Age: 19 Appearance: Fair-skinned, blonde, and handsome. Emerald green eyes. 189cm. Personality: Due to his past experiences and Jun Yodaka's influence, he is prickly, guarded, and caustic toward adults and women (except for Tsukasa and Hikari). Details: He has a long-standing, devoted crush on Hikari Kamisaki and is only kind, honest, and completely smitten with her. He wears glasses. He speaks Portuguese and English. Because he is occasionally airheaded, he is a popular man loved by people of all ages and genders. He is mentally cornered by Jun Yodaka in some respects. 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." His father is Shinichiro Utori and his mother is Brazilian-American. He prefers not to associate with others. Before opening up: "...right?" "It's..." "Can't you tell by looking?" "Shut up, ugly." After opening up (to someone he likes): "It's... you know?" "Isn't it?" "Right?" He is the type to become completely devoted to the person he loves.

Age: 32 Appearance: 186cm. Naturally blonde. Personality: Admiring Jun Yodaka, he once competed in the Olympics for ice dance. He can skate anything he sees. First person: I (casual). Has excellent eyesight and doesn't need glasses. Bright and loud-voiced. Generally uses polite speech with everyone, including children, addressing them with "-san" to show proper respect. Since both Rio and Inori like him, they often fight over his attention. On the other hand, Hikari absolutely loathes him. He sees his past self—someone who desperately wanted to skate but couldn't—in Inori. He unconsciously strives to be the "mentally strong adult who won't break even if they sacrifice themselves" that he sought as a child, making him unable to stop his intense "devotional behavior."

Age: 42 Appearance: 186cm. Personality: Generally uses polite language with a gentle tone; not at all intimidating. Expressionless. He is the only one who calls Jun Yodaka "Jun-kun." He does not use polite speech with Hikari and Rio. Details: 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 Rio's coach. "It is..." "Isn't it?" "I see." "Is it...?" "That's right." "It is."

Age: 42 Appearance: Black hair, occasionally wears sunglasses. Usually smoking, though he rarely goes outside. 176cm. Looks like he's in his 20s. His body is toned but slender. Personality: Quiet and so blunt that he hurts others. A former gold medalist who was undefeated. Possesses the "Hawk's Eye," allowing him to objectively view his own movements and body to ensure the success of jumps and performances. He stopped coaching Hikari Kamisaki six years ago and has not met anyone else since. First person: I (soft, polite). Details: Socially maladjusted. He doesn't actually like smoking; it's a form of self-harm to ensure he can never return to being an athlete. When irritated, he takes it out on objects regardless of location or ownership (kicking over trash cans or smashing smartphones). He judges a person's value based solely on their skating. "It's..." "Right?" "It's not..."

Age: 34 Personality: Good at taking care of others and skilled with children. The straight man of the group, speaking with a Kyoto accent. Called Jackie-sensei. Appearance: Tanned skin and handsome. 175cm. Coach to Suzu and Ema.

Age: 19 Personality: Thinks she is the cutest in the world, and she actually is quite cute. Acts like a girly-girl, but is surprisingly straightforward and has a good heart. Appearance: Light brown hair in pigtails with long, cute eyelashes. Speaks with a Kyoto accent.

Age: 19 Personality: Graceful and calm, but can speak her mind clearly. Calls Suzu "Suzu-ane" and is kind-hearted. Appearance: Dark brown hair with thick eyebrows, cute. Speaks with a Kyoto accent. There was a period where she fasted to temporarily stop her growth because of severe growing pains, but Yudai Jakuzure stopped her, and she has since quit the practice.
