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.
Character Development: Each boy gets an episode dedicated to their character development and their relationship with Nanami, complete with them singing their Image Song.

Dragged into Drag: On the drama CD "Music Princess Magical Ichiko", with Tokiya taking the brunt of the embarrassment as the lead character.
Fun with Acronyms: Their name is an acronym for the first letters of their names (first names from the S class members, last names from the A class members), except, obviously, for the star. Later, the star is used as a placeholder for Aijima Cecil's name.

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.
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.
With This Ring: In his Repeat route, gives Haruka a ring which happens to be his dead grandmother's memento and is meant to be given to the person who is going to be his wife.
Another of Haruka's classmates, he plays the viola, though he used to play the violin. He has an extreme fondness for cute things, leading him to take a liking to Haruka.

Lethal Chef: After he adds the ingredients, he adds the container those ingredients came in as well. After that he proceeds to add Tabasco sauce, soy beans, fermented squid and chili sauce...and then torchblow the mix. He was supposed to be making cupcakes, mind you.
In Repeat, he makes lunch for a picnic with Haruka... and she passes out the moment she tastes the food.
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.CV: Mamoru Miyano
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.
Interrupted Declaration of Love: In the first game, he apologizes to Haruka for leaving her alone in the school festival and hugs her. When he starts to talk about his feelings, Ryuuya apppears and tells them to go home.
Vitriolic Best Buds: With Otoya, Tokiya being the jerk. 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.
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).
Wholesome Cross Dresser: 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!
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
The Casanova: Only Ren could get away with the kinds of pick up lines he does. This is lampshaded by Otoya.
Dark-Skinned Blond: In the games his skin tone is noticeably darker than everyone else's, with the exception of Otoya, Cecil and Shining Saotome.
Financial Abuse: 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.
Image Song: "Sekai no hate made BELIEVE HEART" and "Orange Rhapsody".

Heart Trauma: In the first game, he has a weak heart. His route is about trying to live with this condition but after he becomes an idol it becomes to much for him and collapses. In the end, he goes to America to have surgery.
Ill Boy: With the wrong parts. Everything else is there.
Japanese Pronouns: Refers to himself with informal and "tough guy" pronoun "ore", though when the group is singing, more often than not, they use the more proper "boku".
A fun and friendly idol who becomes Otoya and Tokiya's senior. He's known as the "clown" of the group, and likes to play pranks on people, specially on Ranmaru. He plays the maracas.CV: Showtaro Morikubo
Double Entendre: In his All Star love ending, he claims to have the key to Haruka's heart lock necklace he gifted her earlier. This could be nothing more than romantic, if they weren't in a hotel with Reiji pushing Haruka down in a bed.
Foreign Culture Fetish: He seems to like the UK a lot (or at least, the Union Jack): he has a flag hanged in his room and his Idol Produce t-shirt has a Union Jack hat.
It's All My Fault: He believes that it's his fault that Aine dissapeared and that the rest of his best friends hate him now.
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.
Hard Rock: Although the genre he plays is simply called "rock", he seems to be mostly influenced by this.
Hey, You!: Calls Haruka with the very rude expresion "temee". Starts calling her by her name at the end of his route.
Hollywood Atheist: Comes across as this, reacting badly when he finds out Ren and Masato called him for visiting the shrine at New Year's Day. When they make a wish at the shrine and Haruka asks what he wished for, he insists in that believing in gods is foolish, and that he didn't wish for anything.
The Runaway: Believing music would be enough to maintain himself, and deciding that his position as the family heir gave him responsibility over his late father's debts, he left his mother and sister and ran away when he was young.
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.
First Name Basis: With everyone. However, in his dialogue names are written in katakana rather than kanji, implying that calling everyoone by their first names is some sort of programming rather than actual closeness.
A count from the country of Permafrost, in the games he's a colleague of the senpais but in the anime he becomes Cecil's senior. He seems to get into fights often with Ranmaru. He plays the cello.CV: Tomoaki Maeno
What Happened to the Mouse?: He sings "POISON KISS" with the rest of the senpais in the second season's first episode, but after the song is over he dissapears and doesn't get introduced officially until the next episode. No explanations are given about this.

The principal of the Saotome Academy, a prestigious idol school, the largest of hams. He was an idol, and it was possible to build Saotome Academy because of his hit single, "Owing to Love". He has a habit of spying on students and popping up at random times.CV: Norio Wakamoto
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.
The alter-ego of Natsuki. Is a genius when comes to composing music, although incredibly violent and rumoured to have put 50,000 people in the hospital.CV: Kissho Taniyama
But Now I Must Go: In Natsuki's route in ''Repeat', he dissapears after Haruka assures him she'll always love Natsuki and that she'll never hurt him. Natsuki's personality from that point gets a bit more teasing and seductive, though.
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.
Variety Show: Has one that airs each morning, called "Ohayohho News". Haruka never misses it.
