CV: Creator/MiyukiSawashiro (anime only)

* FriendlessBackground: In the anime at least. In the games she doesn't seem to keep in contact with anyone in her life before she joined Saotome Academy.
* FriendToAllChildren
* GoalInLife: She wants to write music for her idol, Hayato.
* HairContrastDuo: If paired with Tokiya or Masato, her [[RoseHairedSweetie pink hair]] and [[ThePollyanna cheerful disposition]] contrasts [[PinkGirlBlueBoy sharply]] with their dark blue hair and aloofness.

* IllGirl: A former one.
* ImageSong: Gets one in the anime: "Maigo no Kokoro".

* ObliviousToLove: In the anime and some routes of the games. Averted in some routes: [[spoiler: in ''Repeat'', she's the one who confesses to Tokiya.]]
* ParentalNeglect: In the games her parents are never mentioned. In the anime she's raised by her grandmother, meaning they're either dead or very busy.

* DemotedToExtra: In ''All Star''. They only have small roles in the senpai and teachers' routes, and have one single route for all 6 of them and Cecil, the Rainbow Route.

* AffectionateNickname: Reiji calls him "Otoyan" and Ren calls him "Ikki".

* {{Determinator}}: In ''Repeat'' most of his route consists on his determination to find out why Saotome stablished the love ban rule and convicing him to revoke it.
* DisappearedDad: His dad is never mentioned[[note]] At least not directly. His route in the game has quite a bit of fun with the WildMassGuessing trigger on this trope. This actually happens in another route, too. In the same game. [=UtaPri=] likes messing with people.[[/note]] but...
** MissingMom: 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.
* DoggedNiceGuy: To Haruka in the anime. He's very much in love with her, helps her and stands up for her, and comes [[CannotSpitItOut 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.

* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Heights]]: In the games he has acrophobia. In the anime this has been transferred to Syo.

--> Character Twitter entry on 31st Jan 2014: "[super blurry photo of cat] Lookie what I found!"

!Ichinose Tokiya

A student in S Class, he bears a strong resemblance to Haruka's idol, Hayato. However, he's said to be Hayato's identical twin brother instead, and seems to bear a complex from being in his brother's shadow. He appears to be cold and aloof, as well as being a perfectionist. Also the roommate of Otoya from A Class.

* CannotSpitItOut: In the anime. [[spoiler: The "I love you....r songs." scene comes to mind...]]
* CharacterizationMarchesOn: In the games, he's a lot more romantic than his anime counterpart. We also see this reflected on his character songs: compare the more romantic "Nanairo no Compass" and "CRYSTAL TIME" to the much more sexier "Independence" and "SECRET LOVER".
* ChildProdigy: Started being a variety artist at a very young age, which made him become independent and live by himself ''at the age of thirteen'', while also getting top marks in school.
* ContinuityNod: "CRYSTAL TIME", his character song in the second season, includes "Nanairo no Compass" (his ImageSong in the first season) and "Maigo no Kokoro" (Haruka's song) in its lyrics.
* CurtainsMatchTheWindow
* [[DefrostingIceQueen Defrosting Ice King]]
* DemotedToExtra: 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.
* EverythingIsBetterWithPenguins: His Idol Produce t-shirt has one.
* [[spoiler:FakeTwinGambit]]
* {{Flanderization}}: The anime seems to have made him an {{expy}} of Masato, with similar TheComicallySerious reactions but slightly less ridiculous.

* HiddenDepths: In episode 7 he fondly has a memory of children happily asking him to sing, calling him Onii-chan, and it allows him to 'sing with heart'.
** He's extremely romantic compared to what it seems at first glance. The reason is his parents getting a divorce shortly after he made his idol debut, making him think it was his fault.

* ImageSong: "BELIEVE MY VOICE", "Nanairo no Compass" and "CRYSTAL TIME".
* IneffectualLoner

* TheStoic
* {{Tsundere}}

When asked to describe what they like in each other, Otoya rattles off many of Tokiya's good points while Tokiya barely manages to squeeze out two; and then he claims he didn't mean them. Even so he acknowledges Otoya as his best friend and rival, and wants to sing together with him.
* WhipItGood: 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).
* WholesomeCrossDresser: In the fourth episode of season 2, he's seen willingly dressing up in a woman's kimono with a flower in his hair to help Masato get over his inability to hug a person that he doesn't know or love for an audition, even going to the point of using a feminine voice, needless to say, he did a convincing job of being a woman (but wasn't able to get Masato to hug him)
** 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!

!Jinguji Ren

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.

* ChildhoodFriends: With Masato.
* DarkSkinnedBlond: In the games his skin tone is noticeably darker than everyone else's, with the exception of Otoya, Cecil and Shining Saotome.
* FinancialAbuse: He has little to no interest of becoming an idol. He only attends Saotome Academy because his family wants him to, after he graduates he'll be a idol for the Jinguuji's Group commericals.

* SomethingAboutARose
* VitriolicBestBuds: Type 2, with Masato.

* HeartTrauma: In the first game, he has a weak heart. His route is about trying to live with this condition but [[spoiler: after he becomes an idol it becomes to much for him and collapses. In the end, he goes to America to have surgery]].

* FoodAsBribe: Any food from the shop of Reiji's family.
* GrumpyBear
* {{Guyliner}}
* HairColorDissonance: Averted. In ''After Secret'' Masato and Ren refer to his hair as "silver". However, it's not his natural colour.
