Affectionate Nickname: In the anime, Ren calls her "Little Lamb" and later starts calling her "My Lady." Natsuki, Tomochika , and her grandmother also call her "Haru-chan."
Naïve Newcomer: Unlike her classmates, Haruka knows next to nothing about the idol industry (due to living in the country and not having a TV) and doesn't recognize Shining Saotome and Ringo from their idol days.
No Sense of Direction: Apparently. She got lost on her way to Hayato's concert and on more than one occasion after that (including the first episode of season 2). She also gets lost many times in the games.
Performance Anxiety: In the anime, she's afraid to play the piano in front of her class because the first time she was asked to, she couldn't read music and she felt horribly embarrassed. She suffers from it rather severely the second time she's asked to play, as well.
At one point, it gets so bad that just trying to play ends up paralyzing her fingers.
Plucky Girl: Despite her anxiety with performing and the rumors circulating about her, she tries her hardest to study and get better in order to achieve her goals. in the anime, she even manages to master reading sheet music in just a few days from sheer force of will.

Dark-Skinned Redhead: In the games his skin tone is noticeably darker than everyone else's, with the exception of Ren, Cecil and Shining Saotome.
Demoted to Extra: In a sense. He is still part of the main cast in the second season, however, the first season gives him a bigger role and more screen time than other members of STARISH, in the second season, the counterpart of his importance from the first season is given to Cecil.
Disappeared Dad: His dad is never mentionednote At least not directly. His route in the game has quite a bit of fun with the Wild Mass Guessing trigger on this trope. This actually happens in another route, too. In the same game. UtaPri likes messing with people. but...
Missing Mom: His mom died in a plane crash when he was just a baby. His adoptive mother died of illness when he was a small boy. So he's lived in an orphanage up until he was accepted into Saotome Academy.
Dogged Nice Guy: To Haruka in the anime. He's very much in love with her, helps her and stands up for her, and comes very close to confessing to her twice... but she regards him as only a friend, and feels that she's obligated to choose him as her partner only to repay his kindness for her. He seems to take it in stride, though.
Vitriolic Best Buds: With Tokiya, with the twist that Otoya is actually aware of this, and tries not to let Tokiya's cold behavior get to him. And he has his share of vitriol toward Tokiya, too, although the jury is still out on whether he's doing it on purpose or not.

A student in S Class, he bears a strong resemblance to Haruka's idol, Hayato.

Even so he acknowledges Otoya as his best friend and rival, and wants to sing together with him.
Whip It Good: His main weapon as Music Princess Magical Ichiko is a whip. The others note that he looks surprisingly good with it, as he gets a little too much into whipping Otoya (who plays the villain).

In the first game, when the Class S loses a match he dresses up with an uniform. He even asks Haruka for tips to become more feminine!
Student in S Class, he is a son of the Jinguji family, making him rivals with Masato, who is also the roommate. He is very flirtatious, and plays the saxophone. In the anime, he, along with Otoya, helps defend Haruka when the officials refused to let her take the entrance exam.CV: Junichi Suwabe

Dark and Troubled Past: Used to be the heir of a big company, but his father was betrayed and died while trying to pay his debts. Ranmaru took them and started being an idol for that reason. Also, he hasn't seen his mother and his little sister since his father's death; and started being a Jerkass after years of trying to join new bands without succeeding.
Straw Misogynist: In the game, he refuses to work with Haruka at first because he thinks women are useless at composing music. He doesn't trust women because all the bands he joined splat because of women.
Artificial Human: He's actually a robot based on Aine Kisaragi, an idol who dissapeared years ago.
But Now I Must Go: In All Star, towards the end of his route he tells Haruka he's reaching his limit and won't be able to function after the final concert. He passes out after singing his song, but he gets better.

Anime Accent Absence: Unlike Camus (the other foreigner), Cecil speaks Japanese with an accent, and occasionally he stumbles over words and makes mistakes such as reading kanji wrong (he read "tanabata" as "nanayuu"). However, the accent and dodgy Japanese are absent in his songs, which is why Camus first thinks Cecil is just affecting the accent to make himself popular.
Arranged Marriage: In All Star, Cecil is set up for an arranged marriage to Camus' Queen which is later stopped, but not before rebellion and a coup d'état start from the Silk Palace/Permafrost residents.

Chivalrous Pervert: Constantly makes passes at Haruka in the games, but he's obviously screwing around.
Hidden Depths: In Natsuki's route in Repeat, it's revealed his reason for existing is protecting Natsuki from getting emotionally hurt, as he got his heart broken by his violin teacher when he was younger.
Keet: So hard, and to such exclusivity, that his actual self, stoic loner Tokiya grew to really really despise doing the Hayato act. Hence, his enrolling in Saotome Academy to try for a career as his real self.
