Characters originating from the foundation and 2nd Vision titles. This includes, but not limited to: THE iDOLM@STER, The iDOLM@STER 2, THE iDOLM@STER: Dearly Stars, and anime/Drama CD/manga based directly off these properties. They are collectively considered the core cast of iM@S.
Main Idols (765 Production)The focus of much of the story of both the games and the 2011 anime adaptation.
- Bare Your Midriff:
- Berserk Button: In no particular order: insulting 765 Production, the idols' bonds of friendship, their passion for music, or their Producer. Even laidback Azusa and cowardly Yukiho will become righteous if you cross that line.
- Color-Coded Characters: Each idol has her theme color as highlighted on their images.
- Cover Version: Outside of their respective Master Artist CD as noted below, the idols sometimes cover random songs in their radio show, and in turn this gets compiled into several CDs worth of mainly short cover songs (alongside of monologues and such).
- The Eleven O'Clock Number
- Gratuitous English: Nearly every song produced for the series contains at least one English word in the lyrics. If it doesn't contain an English word, it probably uses French or Italian instead.
- Idol Singer
- Music for Courage
- Power Trio:
- From the games, Miki, Takane and Hibiki form Project Fairy in the SP series, and Iori, Ami and Azusa form Ryuguu Komachi in The iDOLM@STER 2 and the 2011 anime. Both are rival units in the games.
- One of the manga adaptions, The iDOLM@STER 2: The World Is All One!! has SprouT.note This group includes Haruka, Yukiho and Hibiki.
- Considered the "main characters" of the series, Haruka, Chihaya, and Miki are also frequently grouped together as one of these in promotional materials and the series itself.
- Besides (and including) all of the above, the player may create his own in the games.
- Ragtag Bunch of Misfits: How the group initially begins. They have the talent and will, but lack the training and stage experience. It's not the world at stake, but it certainly is 765 Production's future on the line.
- This Is Your Song: Yakusoku ("Promise"), which was written by the idols for Chihaya in the anime after she'd gone into an isolated depression when a tabloid revealed a dark secret.
- True Companions: Especially in the anime adaptation.
- Undying Loyalty: The idols all have it towards each other and the Producer.
Everything between parentheses on the profiles means that they changed and/or were added by "THE iDOLM@STER 2".
Haruka is the main character; a cheerful, hard-working 16-year-old. A simple love of music and entertaining together with others drove her to become an idol. Her special talents are that she has none.
- Adaptation Dye-Job: Had brown eyes in the original arcade version, which were changed to green in all subsequent appearances.
- Big Bad: Okay, not really, but in the 2011 anime's in-universe Mujin Gattai Kisaragi movie she is cast as this. She seems to have enjoyed it.
- Clark Kenting: In the 2011 anime's second half.
- Cover Version: Has covered "Moonlight Densetsu" from Sailor Moon, "Sore ga, Ai deshou?" from Full Metal Panic? Fumoffu, and "Tips Tap Tip" from Eureka Seven.
- Cute Clumsy Girl: Unless she's focusing really hard on her movements, such as when dancing, she will fall over her own feet. She considers not tripping once in a day an accomplishment.
- Enforced Method Acting: Haruka gives a heartbreaking performance in a musical audition, and handily lands the lead role. Unbeknownst to anyone, she was struggling with a bout of depression made worse over trauma from the Producer's terrible accident that she blamed herself for. The 'perfect' audition was Haruka genuinely having a nervous breakdown.
- Hair Decorations: Her ribbons. She always wears them. Always.
- Because of this, Haruka has a mild ribbon motif.
- The Heart: The girl who keeps the others' spirits high. It's telling when, in Episode 24 of the anime, everyone is shown to be sad and worried about her when SHE'S at her low point.
- Genki Girl: More subtle than Yayoi at least.
- Idiot Hero
- Image Song: "Taiyou no Jealousy", "I Want", "Otome yo, Taishi wo Idake", "START!!", "Sayonara wo Arigatou", "Suteki Happiness" (main series), "Kimi ga Ite Yume ni Naru", "Kirameki Shinkoukei" (Million Live), "SWITCH ON!", and " Maemuki de Ikou♪" (Puchimas).
- Lethal Chef: See One-Note Cook below.
- Mad Libs Catch Phrase: While not used in-universe, the real world advertisements often have her saying "Producer-san, it's [thing]! [thing]!!"
- Nice Girl: Probably her most immediately noticeable trait.
- One-Note Cook: Can't cook anything edible other than sweets. Averted in the anime where she not only teaches Chihaya (who had been living on convenience store lunches) how to cook, but also manages to fix a dish on a competition cooking show after Chihaya gives her the wrong sauce.
- Plucky Girl: Her defining trait. Her optimism is the glue that holds the group up.
- Red Is Heroic: Considered the "main character" role of the idols, is the lead for most concerts that involve all the idols, and is the girl who primarily keeps the team's spirits.
- Ridiculously Average Guy: Even the President thinks she is. What sets her apart is her infectious optimism. However, in iM@S 2 her vocal stat is shown to be above average (though it isn't as high as Chihaya, who has the highest vocal stat out of all the idols).
- The Rival: To Miki. Not only in the idol business but also for Producer's affection.
- Series Mascot: She is this for the entire iDOLM@STER franchise.
- Standardized Leader
- Thinking Tic: When in thought she tends to look up and to the right or left. A part of the fandom ran away with it and created "Nonowa." It became an Ascended Meme when it appeared in Episode 7 of the anime, while Hibiki was tending to Yayoi's younger siblings.
- Yandere: Some fans' interpretation of Black Haruka.
A talented and serious 15-year-old who became an idol in order to improve her singing. She isn't really thrilled by the flashier aspects of her career, and is rather fond of classical music.
- A-Cup Angst: Flanderized amongst fanworks. It doesn't help that come iM@S2 she's the only idol whose bustline hasn't grown an inch. The 2011 anime even lampshades on this come the Beach Episode.
- Adaptation Dye-Job: In the arcade game Chihaya's hair started off black with a slight blue tinge. It graduated to full on blue from the Xbox 360 port and onward.
- Adorkable: The Puchim@s version where she wants to name all the Puchis Gonzales. It's weird, but she looks so enthusiastic about it, it makes her look cute.
- Aloof Dark-Haired Girl: Her original video arcade counterpart had black hair.
- Ambiguous Disorder: It's entirely possible that Chihaya has a mental disorder known as Schizoid personality disorder, as she is largely emotionally cold, has little external sense of motivation or goals outside of singing, has a tendency towards a solitary or sheltered lifestyle, such as shutting herself away from others to focus only on singing or exercise, and has trouble establishing personal relationships or expressing their feelings meaningfully (which explains why other idols have considered her to be "cold and heartless" in some situations).
- Bluebird of Happiness: Chihaya's character is built around symbols of the bluebird of happiness (two of her image songs, Aoi Tori and Nemuri Hime, contain direct references), which ties into her desire to handle her life herself and find meaning her own way. The anime mentions this but does not develop it.
- Classically Trained Extra: A musical version. Chihaya only became an idol to improve her singing skills, at least initially disliking promotional work and other aspects of an idol career.
- The Comically Serious
- Cover Version: Has covered "rise" from Ghost in the Shell: Stand Alone Complex (which doubles as Gratuitous Foreign Language, in this case Russian), "Shangri-La" from Fafner in the Azure: Dead Aggressor, "Chiisana Mono" from Pokemon Jirachi Wish Maker, and Romeo's Blue Skies' "Sora e...".
- Cry Cute: The end of Episode 20, after finishing her song at the end of 765's autumn concert, even as she sees a younger specter of herself and Yuu apparently watching her sing.
- Dark and Troubled Past: Her parents started fighting all the time ever since her little brother Yuu died when he got run over in a parking lot.
- Failure Is the Only Option: Every time she suggests naming one of the Puchidols "Gonzales", either another idol will give said Puchidol a name or said Puchidol has already been named. The one time she tries a different name (Piyo-Piyo) she actually succeeds.
- Famed In-Story: By the time of the 2nd Vision games.
- First-Name Basis: In the games, upon the first meeting, she demands Producer call her "Chihaya." In fact, she doesn't like being called by her family name.
- Hopeless with Tech: She's shown to be like this in the games when trying to buy an MP3 player, which is kind of weird since she's the one assigned to do the Audio Tech's job during their first stage performance in episode 3 of the anime. Her phone in the anime is shown to be a model reminiscent of those from the nineties. Compared to those some of the others own, it's likely meant to allude to this.
- Ill Girl: In iM@S2, she has a fever twice throughout the story. It is a sign of her chronic throat inflammation.
- Image Song: "Aoi Tori", "Me ga Au Toki", "arcadia", "Nemuri Hime", "Yakusoku", "Saihyou" (main series), "Just be myself!!", "Snow White" (Million Live), "choco fondue", and "Shikkuri to Yukkuri to" (Puchimas).
- Minor Living Alone: In most iterations, she's either doing this from the beginning, or she moves away from her parents mid-story. She does not like being around her parents due to her Dark and Troubled Past.
- Not So Stoic: She has been known to crack up at the lamest jokes.
- Serious Business: Her attitude toward singing. She's not fond of any extracurricular activity that doesn't involve her career, hates doing promotional work, and spends her free time listening to classical music and training her voice.
- Stepford Smiler: Pretends so hard to be cheerful for the Producer.
- Sugar-and-Ice Personality
- Unwinnable: In the original Arcade game, she is notoriously prone to this. She gains only slight improvements to her tension in events, but large losses if you say the wrong thing, or mess up on a lesson minigame. Because you're working on a time limit, her tension going too low results in an inescapable death spiral. Thankfully, the console version can do a Save Scumming to prevent it. This is entirely realistic for a character with depression and social anxiety.
- You Gotta Have Blue Hair
A painfully shy 16-year-old from a traditional household who's prone to frequently bursting out in tears. She became an idol hoping to shed her fragile persona.
- A-Cup Angst: She's actually got a decent bust, but she still thinks she's flat. This bugs Chihaya and the Futami twins.
- Adaptation Dye-Job: In Xenoglossia, her hair is of a darker tone.
- Beware the Nice Ones: Specifically in the Puchim@s! series. She is one of only three characters who can stop Harukasan's Zerg Rush rampage, but only when she has her back against the wall.
- Blue with Shock: Whenever she panics. Sometimes it's accompanied by Dull Eyes of Unhappiness.
- Catchphrase: "I'll go bury myself!" (whenever she becomes extremely embarrassed)
- Childhood Friends: With Makoto.
- Cover Version: Has covered Perfume's "Sweet Donuts", "For Fruits Basket" from Fruits Basket and "Natsukage" from AIR.
- Curtains Match the Window: Brown hair and eyes.
- Does Not Like Men: She's afraid of them. However, the Producer can become the only non-familial man she can remain comfortable around, and in the anime she's very taken with Makoto's Bifauxnen side.
- Hidden Depths: She does have inner strength, but it's hidden by her shyness. She joins 765 to shed her shy exterior.
- Image Song: "First Stage", "Kosmos, Cosmos", "ALRIGHT*", "Nando mo Ieru yo", "First Step", "Ano Hi no Namida" (main series), "Humming Road", "Impervious Resolution" (Million Live), "Negai Hitosu", and "Pu-ru-ru" (Puchimas).
- Literal-Minded: Sometimes she takes her catch phrase a bit too literally by taking a shovel out of nowhere and actually begin digging.Yukiho Hagiwara: I'll dig a hole and bury myself in it!Ai Hidaka: Whaaa, you can't dig a hole in the hallway!!
- Lovable Coward
- Nice Girl: Apart from her shyness and phobias towards men and dogs, she is generally portrayed as this.
- Prone to Tears: She wants to shed this aspect of her.
- Seasonal Motif: Winter and snow. Her name includes the character for snow, her birthday is on Christmas Eve, she tends to be highly associated with songs about winter or with winter themes (such as "Little Match Girl") - even her unique outfit in One For All has wintery and snowy elements attached!
- Shout-Out: One of Yukiho's Cinderella Girls cards is of her cosplaying as◊ Anise Tatlin.
- Significant Birth Date: Christmas Eve. Yukiho's is one of the only birthdays that tends to be regularly addressed in storylines, and feeds into her heavy snow motif.
- Singing Voice Dissonance: Her singing voice is not as meek or hesitant as her regular speaking voice.
- Sparkling Stream of Tears/Tender Tears: Tends to cry a lot.
- Tomboy and Girly Girl: The Girly Girl to her Tomboy best friend, Makoto.
- Why Did It Have To Be Dogs?: Even chihuahuas scare her.
- Yakuza Princess: The most common fan explanation for her odd behavior with men and her father's secretive occupation. He's likely to either be that, or the head of a corrupt Zaibatsu.
- Adaptation Dye-Job: In Xenoglossia, her hair is more reddish than orange. Also, in the original arcade game, she had brown eyes and more brown-shaded hair which were changed to teal and orange respectively in all subsequent appearances.
- Airplane Arms: She bows with her arms in this position, in a manner resembling scissor doors.
- Big Eater: "Ohayou!! Asagohan," one of her image songs, is all about starting the day with a good breakfast, and in other media, she's shown to greatly enjoy meal times.
- Book Dumb: Yayoi is not the smartest of girls, hence why she gets low grades at school. In One For All she asks the producer to tutor her, calling him "sensei" during much of the route.
- Covert Pervert: Touching her chest in some scenes occasionally raises her tension instead.
- Cover Version: Has covered Perfume's "Sweet Donuts" and "Kaerimichi" from Bakemonogatari.
- Cry Cute
- Cute and Psycho: In the Puchim@s! series, when dealing with Harukasan.
- Genki Girl
- Girlish Pigtails
- Image Song: "Ohayou!! Asagohan", "Kiramekirari", "Genki Tripper", "Smile Taisou", "Pure Sonic Love!" (main series), "Heartwarming", "Strawberry Cupid" (Million Live), "Mahoroba", and "Kangeki Happy Ecology" (Puchimas).
- Incorruptible Pure Pureness: She's so naive that during communications, that if the player touches her chest in the games (intentionally or otherwise) she immediately assumes they are talking about her heart.
- Innocent Blue Eyes
- Kawaiiko: So cute Hibiki even said once that she wanted to take her home.
- Massive Numbered Siblings: She's the oldest of six children.
- No Indoor Voice: In her iM@S2 introduction, she's told by Kotori that she'd ruin the recording if she kept being so loud.
- Perpetual Poverty: Helping her family make a living is why she became an idol. In the games her regular outfits all look similar to each other even when compared to other girls' outfits, and in the anime, she's shown to have a rapport with an employee at a local supermarket who sticks 50-percent off stickers on some groceries for her.
- The Pollyanna
- Primal Fear: She is deathly afraid of heights, to the point of screaming and crying for help when trying to look down at the ground.
- Saying Sound Effects Out Loud: She usually uses onomatopoeia on her speech.
- The Scrooge: She doesn't come off as greedy, but she is known to go to great lengths to scrounge up a few bucks, even searching under vending machines for loose change. Even as a hugely successful idol she spends her spare time doing menial chores for cash.
- Token Mini-Moe: She's the shortest of the 765 Idols.
- Verbal Tic:
- Of the "Catchphrase that isn't really even a word" variety. U-uu!
- She also announces her high-fives with "hi-touch"!
- Zettai Ryouiki
A focused, industrious 18-year-old who originally joined 765 as an intern, but became an idol due to shortage of talents. Even as an idol she still handles the business side of her career.
In iM@S2, she officially retires from performing and becomes the producer of Ryuuguu Komachi.
- Adaptation Dye-Job: In Xenoglossia, her hair is of a lighter tone.
- Brainy Brunette
- The Call Knows Where You Live: Officially, she retired as an idol in the second game so she could follow her dream career in management. But various circumstances like fan demand, need for an extra unit member or Haruka wanting her to be part of the group performance are always dragging her back to the stage.
- Cannot Spit It Out: In Puchim@s! she is hopelessly in love with the Producer... whenever he's not doing anything stupid.
- The Comically Serious
- Cover Version: She's covered "Sorairo Days" from Tengen Toppa Gurren Lagann.
- Curtains Match the Window
- Drill Sergeant Nasty: In the anime she gets labelled with this moniker pretty much word-for-word, courtesy of Ami and Iori. Her actual behavior isn't quite as extreme as the trope implies, though.
- Expository Hairstyle Change:
- In iM@S2, she switches her hairstyle from two upturned pigtailed braids to a high bun that better fits with her role as a producer. She continues to use this stytle in One For All and Million Live.
- She changes her hairstyle again for Platinum Stars and Stella Stage, this time to a large braided ponytail.
- For Million Live Theater Days she goes back to two pigtailed braids without their old upturn, likely because Konomi Baba already had a braided Motherly Side Plait hairstyle.
- First-Name Basis: In iM@S2, the Producer uses "Akizuki-senpai" at first due to her being a senior at work. She then tells him to call her "Ritsuko" instead because she is younger than he is.
- Four-Philosophy Ensemble: When she was with Ryuuguu Komachi, she was the Realist.
- Four-Temperament Ensemble: When she was with Ryuuguu Komachi, she was the Melancholic.
- Girlish Pigtails: Her original hairstyle were braids a la Wendy's mascot. In iM@S2 she'll occasionally switch back to this style depending on the outfit you have her wear.
- Hair Antennae
- Hidden Depths: She is proficient in MMA, as a drama CD details her using it to beat up some thugs wanting to kidnap Yukiho.
- Hot Librarian
- Image Song: "Mahou wo Kakete!", "Ippai Ippai", "livE", "Love Order-Made", "Watashi Datte Onnanoko" (main series), "GREEDY GIRL", "Liar's good bye" (Million Live), "WEDDING BELL", and "Q&A" (Puchimas).
- Meganekko: While Ritsuko's personality isn't quite in line with the character type, her being a glasses-wearer is played up heavily. The final lines of Ippai Ippai ask whether or not you like her glasses, and in most games that feature costume changing (except the SP series and Platinum Stars) glasses-based head accessories do not replace her regular frames and sit on her head instead.
- Only Sane Woman: How she interprets life with her coworkers, when things get too extreme.
- The Smart Guy
- Team Dad: She's the second-oldest idol of the 765 Allstars (only Azusa is older), and she's often more disciplinarian towards the other idols compared to the Producer.
- Tomboyish Ponytail: A braided version of this is her hairstyle in Platinum Stars.
- Tsundere: In the various anime or manga media, where she has feelings for the Producer. Puchim@s! being the most obvious.
- She'll occasionally act like one in the games as well, though nowhere near to the extent that Iori does.
The oldest of the idols at age 20, Azusa is an easygoing, hopeless romantic. She became an idol hoping to gain more attention and ultimately find her "destined one."
In iM@S2, she is a member of Ryuuguu Komachi.
- Adaptation Dye-Job: Like Chihaya, her hair started off black. It changed to blue in the Xbox 360 port, then a dark purple in the SP games. As of iM@S2 it has gone back to blue.
- Beware the Nice Ones: More prevalent in SP, when after awhile being her usual innocent ditz self, the insults of Kuroi towards the Producer and Miki made her talk him down such that even Kuroi wasn't able to talk back, all while looking as calm as ever. Even Miki and the Producer note that she's scary this way.
- She is a master at joint lock techniques, similar to Aikido, and claims she never took martial arts.
- Catchphrase: Due to her overall ditzy innocence, it may as well be "Ara ara..." (or sometimes just one "Ara") (or "Oh my...")
- Character Tics: Placing her palm on the side of her face while her eyes are closed in the anime.
- Christmas Cake: She isn't one yet, but it's pretty clear the chance of becoming one fuels her search for a significant other.
- Cool Big Sis: To the rest of the idols.
- Cover Version: She's covered "reflectia" from True Tears and "Kiss Me Good-Bye" from Final Fantasy XII.
- The Ditz: Despite being the oldest idol, she's certainly more scatterbrained than many of her younger compatriots.
- Expository Hairstyle Change: In iM@S2, and a few episodes into the 2011 anime, she has cut her hair to a short bob.
- First-Name Basis: At the conclusion of Missing Moon and after her love confession to him, she wants the Producer to drop the formalities and just call her Azusa. He has difficulty adapting to this.
- Four-Philosophy Ensemble: When she was with Ryuuguu Komachi, she was the Apathetic.
- Four-Temperament Ensemble: When she was with Ryuuguu Komachi, she was the Phlegmatic.
- Gainaxing: In the games, all the idols have it to various degrees, but in the anime it's Azusa all the way.
- Hello, Nurse!: Mostly in the anime, where there's nearly NO man who'd pass up the chance to ask her out for a date (even if she's clueless and probably refusing). Which leads to...
- So Beautiful, It's a Curse: The entire cityscape (and even the zoo animals) are entranced by her beauty when she runs through the streets in a wedding dress. Eventually it starts a stampede.
- Idiot Hair: Which becomes weaponized in her 'counterpart' in Mujin Gattai Kisaragi, the AzuScythe.
- Image Song: "9:02 pm", "Tonari ni...", "Mythmaker", "Lovely", "Hare Iro", "Koi Kokoro" (main series), "Nageki no FRACTION", "Tsuki no Hitori de" (Million Live), "zone of fortune", and "LOOK THE SKY" (Puchimas).
- The Ingenue: Her innocence is a defining trait and informs her "Destined One" dream.
- It's Not You, It's Me: She uses variations of it as a response to people who ask for dates or confess their love. The Producer is an exception.
- No Sense of Direction: Taken to extremes when she somehow winds up on the other side of the planet.
- Obfuscating Sexuality: Azusa typically shows ignorance about her exceptional beauty and impressive bust. Yet when she shows interest in the Producer, she will subtlety leverage these traits to get his attention.
- Sacred First Kiss: The Producer can steal it during an event in iM@S1, when pretending to be her fiance. If he does, she realizes she didn't mind it was him.
- The Tease: Within the games, towards the Producer. Her routes are written so that in the end, the player can infer Azusa believes the Producer is the "destined one" she is looking for. She never flirts with other men using the same friendliness, and in Missing Moon, Miki takes notice of her behavior and gets rather upset about it.
- Unsuspectingly Soused: It doesn't take much alcohol to get her drunk. Unfortunately, Azusa loves the taste of alcohol and won't turn down a glass if offered. On the other hand, she can drink LOTS of it before actually passing out, and tends to be happy while intoxicated... just don't bring up that she doesn't have a boyfriend.
- Weddings in Japan: Her ultimate goal. She's exclusively set on having it Western style, and there wasn't official artwork of her in the traditional Japanese bridal white kimono until a Million Live card with her wearing one came out mid-2017.
- Western Zodiac: She's a huge fan of them, hoping they'll eventually lead to her "destined one."
The rich, spoiled 14-year-old daughter of a corporation CEO acquainted with 765 Production's president. She is sickeningly sweet towards complete strangers, but incredibly sharp-tongued to everyone else (i.e., the staff, her fellow idols, and even the Producer). She became an idol to prove to her father that she could become successful on her own terms.
In iM@S2, she is the leader of Ryuuguu Komachi, and is quite enjoying her new taste of stardom.
- Adaptation Dye-Job: In Xenoglossia, her hair is black. Similarly, her original arcade counterpart had brown eyes before being changed to pink.
- Berserk Button: One easy way to tick her off is to refer to her as "Deko-chan", Miki's nickname for her.
- Bitch in Sheep's Clothing: Downplayed; she acts cute and sweet towards strangers, but not towards those who know her. Despite her usually abrasive attitude, though, she is a genuinely good person.
- Cover Version: She's covered "Ren'ai Circulation" from Bakemonogatari and Onyanko Club's "Valentine Kiss".
- Cry Cute: The end of her story, when she tries to viciously (and tearfully) insult the Producer, saying she's glad she won't have to put up with him being stupid and useless anymore.
- Does Not Like Spam: Her arcade profile states that she hates roast beef and carbonated drinks.
- Epic Fail: In episode 2 of the anime, seeing Miki's much more mature body made Iori self-conscious about her own, so she tried to look sexy and mature for her photo spread, and roped Yayoi and the twins into it with her. They took to stuffing their bras with fruit and wearing clown makeup. Eventually the Producer taught them all to just be themselves and they would be as pretty as Miki.
- Expository Hairstyle Change: In iM@S2, her hair is slightly shorter and has a bang out of her hairband.
- Fast-Forward Gag: In Puchim@s!, some portions of her interviews are fast forwarded to make them fit the time limit, since she talks endlessly about herself.
- Forehead of Doom: A defining trait of hers.
- Ghost Story: Has quite the talent for making them up on the spot.
- Girls Are Really Scared of Horror Movies: For Iori herself it's reversed, as she loves telling them... because the majority of other idols follow this trope. However, when confronted with the possible sight of an actual ghost, she gets just as afraid as the others.
- Girls Love Stuffed Animals: She carries around a stuffed rabbit named "Usa-chan/Charles Donatello The 18th" with her at all times. In some of her more casual stage outfits, the rabbit tags along too, glued to her arm.
- Four-Philosophy Ensemble: When she was with Ryuuguu Komachi, she was the Cynic.
- Four-Temperament Ensemble: When she was with Ryuuguu Komachi, she was the Choleric.
- Hair Decorations: In both hairstyles she has an Alice band.
- Image Song: "Here we go!!", "Futari no Kioku", "L'isola", "DIAMOND", "Zenryoku Idol" (main series), "Private Road Show (playback, Weekday)", "Chikyuu Mirror Ball" (Million Live), "Royal Straight Flush", and "Episode Love" (Puchimas).
- Kawaiiko: Iori acts so cutesy on purpose so she can become popular as an idol.
- Lonely Rich Kid: The reason Charles is so precious to Iori is that it was her only friend since childhood, as the only people who ever had much contact with her were maids and butlers. You can catch her talking to him from time to time.
- The Ojou: Daughter of a big time CEO. A brattier variety of ojou than Takane.
- Omniglot: Like Takane, she's fluent in a number of languages.
- Screw the Rules, I Have Connections!: Invoked and inverted in the same dialogue during Episode 10, when she blackmails the producer of Shinkan Shoujo Pro, who's planning to force 765 to lose on purpose, into playing by the rules with the fact that her family is the major stockholder for his idol group's parent company.
- Security Blanket: Charles.
- Self-Made Woman: Her goal is to become a success without help from her father or brothers.
- Shana Clone: Downplayed. She isn't a lead character and isn't physically violent, but covers other traits well (childlike stature, dresses as regular attire, heavy tsun attitude, a habit of addressing others with "anta," slight breast envy to the more endowed ones, and wealth).
- Spell My Name with an "S": The same capital I vs. lowercase L conundrum that plagues Ievan Polkka leads some western fans to believe her name is Lori.
- Spoiled Sweet: Iori has ego in spades, but she's short in arrogance. Her best friend among the other idols is always-short-on-cash Yayoi, and she is not above doing her part on chores and eating commoner's food.
- The Trickster: She doesn't pull pranks as frequently as the twins, but she won't turn down an opportunity to pull one. Especially enjoys the I Lied variety.
- Trademark Favorite Food: Iori quite likes 100% orange juice. In The iDOLM@STER 2 you can choose to answer her request for some as part of the tutorial, in One For All it's her favorite drink in the vending machine minigame, and she's otherwise demanding that you get her some after lives somewhat often.
- Tsundere: An unusual A/B hybrid for her seiyuu, a Type A specialist — Type B around people she wants to manipulate, type A around everyone else, especially the Producer.
- Lampshaded by Eri in the Dearly Stars game. She easily noticed how quickly she changed her personality - from dere while she was just a stranger to Iori, to tsun after they spent some time together in the waiting room before the finals of an idol contest. She even asked "Iori-san... are you a tsundere?", which did not please Iori at all. Not surprising, as being an Otaku, Eri is fully aware of tsundere characters' habits.
- "Well Done, Daughter" Gal
16-year-old Makoto was raised as a boy by her father, who always wanted a son. As such, she uses masculine pronouns and is good at sports and karate, and gets more attention from girls than boys. Ultimately she came to resent it, wishing she could be more feminine and get more attention from boys, so she became an idol to try to reinvent herself.
- Action Girl: While modeling for a swimsuit edition of an idol magazine, she proposes a shot of her leaping from the roof into the pool. Taken to the next level in Episode 8, where she has an epic kung-fu fight with grunts atop a ladder bridge while wearing a tuxedo.
- Bifauxnen: Much to her annoyance, she is often mistaken for a boy. In episode 8 of the anime, which has a wedding theme, she had to model a groom's clothing because the wedding chapel requested a guy and 765 only had Makoto. The fact that she looks so boyish is the main reason she has so many female fans In-Universe.
- Bokukko: Her masculine speech patterns don't help her attempts to become more feminine.
- Boyish Short Hair: Though she's starting to grow it out.
- Cat Smile
- Chick Magnet: A running gag is how her In-Universe fanbase mostly consists of teen girls with a crush on her thanks to her Bifauxnen looks. In the anime, she even attracts housewives.
- Childhood Friends: With Yukiho.
- Cover Version: Has covered "Seikan Hikou" from Macross Frontier, "Groovin' Magic" from DieBuster, and "Unbalance na Kiss wo Shite" from YuYu Hakusho.
- Cute Bruiser
- Expository Hairstyle Change: It took her four games, but as of iM@S2 and the anime it has occurred to her that letting her hair grow out may be a step towards looking more feminine. Rumor has it that Gackt is the inspiration for her new haircut, because apparently Japanese people are entranced by the concept of styling gel.
- Femininity Failure: Often. This is usually because she's trying way too hard.
- Gender-Blender Name
- Girliness Upgrade: She often tries to invoke this on herself, but she's rarely successful. Note to Makoto — Cutifying yourself, making up "cute noises" and calling yourself "Mako-rin" doesn't work.
- Girls Love Stuffed Animals: Collecting them is a hobby of hers.
- Girly Girl: Wants to be one of these but isn't. For instance, in episode 8 she was disappointed that she didn't get wear a 'cute frilly dress' like Azusa and Miki.
- Hair Antennae
- Image Song: "Agent Yoru wo Yuku", "Meisou Mind", "Jitensha", "tear", "Cheering Letter", "Zekken, Arui wa Nigerarenu Koi" (main series), "FLY TO EVERYWHERE", "WORLD WIDE DANCE!!!" (Million Live), "Yooi Don!!", and "Taisetsu na Hito" (Puchimas).
- Jack-of-All-Stats: In the game, although she is proud of her dancing skills, her skills are perfectly average. For those unable to play you can check out this video here. You can see her skills at 1:53.
- Mama Bear: Towards Makochii in Puchim@s.
- One of the Boys
- Paper-Thin Disguise: In the anime, she tries to sneak past her fangirls by wearing a hat and a jacket. It doesn't work.
- Raised as the Opposite Gender: She was raised as a boy by her father as he wanted a son.
- She Cleans Up Nicely: When she doesn't overdo it in being feminine, she look greats in dresses and other girlish attire. In Shiny Festa Groovy Tune, her appearance in the edeN music video is a good example.
- Tomboy: Her dad raised her to be boyish but she'd rather be a Girly Girl.
- Tomboy with a Girly Streak: Despite all her attempts to become a Girly Girl, this is ultimately what she is.
- Why Did It Have To Be Cockroaches?: Went stiff and panicky when Iori jokingly mentioned out loud that there's one in the office.
Ami and Mami Futami
A pair of hyperactive 12-year-old twins, and the youngest of the bunch, who became idols because it sounded fun. They take turns performing under Ami's name.
In iM@S2, Ami is a member of Ryuuguu Komachi while Mami is produced separately.
- Bratty Half Pints
- Brick Joke: Whenever the twins want to decide a friendly argument for something (like who gets the last slice of cake), they restort to a game of jan-ken-pon. Because of their Single-Minded Twins factor, they ALWAYS call out the same choice over and over again, meaning it ALWAYS results in a tie. The viewer/reader never gets to know how an outcome is ever reached.
- Buffy Speak: "If we become a super-cool-awesome idol, then everyday will be relaxing right?"
- Cover Version: Mami has covered Perfume's "Sweet Donuts" and Ami has covered "Lum no Love Song" from Urusei Yatsura; both twins have covered "Aozora no Namida" from Blood+ and "Wonder☆Winter☆Yattaa!!" from Pretty Cure Max Heart.
- Dirty Kids: They have shades of this.
- Divergent Character Evolution: If one pays attention in the arcade and first Xbox 360 games, Mami turns out to be a little more mature than Ami. In the SP games, Takane figured out that they were two different people when she made eye-contact with Mami and saw that she was more mature. Come iM@S2, the twins get separate careers, Mami changes her hairstyle and Ami becomes part of Ryuuguu Komachi, so it's likely that this will continue.
- The twins are producible as entirely separate characters in One For All, with unique plotlines and goals for both. In particular, the basis of Mami's story is her desire to distance herself from the Twins gimmick she feels she is trapped in.
- Every Girl Is Cuter with Hair Decs
- Expository Hairstyle Change: In iM@S2 Mami still keeps her hair in a side ponytail, but it's grown longer than Ami's.
- Fashionable Asymmetry: Their cute&girly outfit in iM@S2. They have two different pairs of boots between them, having traded the left ones.
- Four-Philosophy Ensemble: When Ami was with Ryuuguu Komachi, she was the Optimist.
- Four-Temperament Ensemble: When Ami was with Ryuuguu Komachi, she was the Sanguine.
- Gamer Chicks: Devoted gamers who carry their handhelds with them everywhere, although the Xbox port of the first game had to edit out their Gameboy Advances due to the Console Wars.
- Genki Girls
- Genre Savvy: Most likely to give genre send-ups in the anime, such as when they pretended they were "sexy girl detectives" solving the mystery of Iori's lost pudding.
- The Heroes: How they are cast in Mujin Gattai Kisaragi.
- Identical Twin ID Tag: They start out with the same hairstyle, but with Ami's side ponytail being on the left of her head and Mami's side ponytail on the right. In iM@S2, Mami has grown out her hair, making it easier to tell her apart from Ami.
- I Got Bigger: Between the first game and the second, the twins shot up from the smallest idols to towering over girls several years their senior.
- Image Song:
- Both twins: "Positive!", "Start Star", "Reimei Starline" (main series), "Doki Love Attraction", and "Dokkiri Happy Birthday" (Puchimas)
- Ami: "YOUou MYshin", "Triple Angel" (main series), "Hohoenda Kara, Kidzuitanda", and "Time Machine ni Tobinotte!" (Million Live)
- Mami: "Jemmy", "Houkago Jump" (main series), "DETECTIVE HIGH! ～Koi Tantei Monogatari～", and "WOW! I NEED!! ～Singing Monkey Kashou Ken～" (Million Live)
- In the Name of the Moon: Word for word in Episode 9, complete with an over-the-top pose."With our little grey cells and seven-colored faces, the sexy girl detectives Ami and Mami, in the name of our Grandmother and Grandfather, and in the name of the moon, will capture the culprit."
- Leaning on the Fourth Wall: Drop hints from time to time that they are aware they're in a video game/TV show. Loading screens for songs usually involve one of the twins singing "Loading~loading" to a jaunty tune.
- The Nicknamers: They have cutesy nicknames for all the other idols (Iorin for Iori, Miki-Miki for Miki, Yuki-pyon for Yukiho, etc.) and they address the Producer as "nii-chan" instead of "Producer".
- Repetitive Name: Ami and Mami Futami.
- Single-Minded Twins: Sometimes it's played straight and sometimes it's deconstructed. Largely depends on the author or story sketch. Nonetheless they tend to finish each other's sentences, speak in unison, and scheme the identical ideas simultaneously.
- Tag Team Twins: In the first game, they take turns performing under Ami's name.
- Theme Twin Naming: Their full names are both very repetitive.
- Third-Person Person
- Trickster Twins: They're both very mischievous and like to pull pranks, especially in the first game where they take turns performing under Ami's name.
- Twin Switch: Their gimmick during the first game.
Laid-back 14-year-old Miki thinks she can breeze through the idol ladder, given that she already gets good grades without much effort, gets 20 love confessions a day, and manages to stay in shape in spite of sleeping a lot. She debuted in the first game's Xbox 360 version, and is the only character to have an alternate story route.
- The Ace: Deconstructed. Miki is so effortlessly, ridiculously excellent at everything she ever tries that she never had to put any effort into anything, causing her to grow up into a lazy, unmotivated, somewhat selfish person with little ability to maturely confront failure. This behavior was not only tolerated, but encouraged by her father, a powerful politician who kept drilling into her that with his connections and resources she'll never have to work a day in her life. It takes a lot of trauma to finally get her to realize that really making your dreams come true takes work, but when she's done, she ends up arguably the best idol of 765 Pro (in terms of both skill and popularity).
- An Odd Place to Sleep: In episode 26, she took a nap on a crate carrier.
- Awesome Mc Coolname: A rough translation of the kanji that make up her full name could be "A beautiful rarity from the well of stars". This feeds into her star motif.
- Born Lucky
- Brilliant, but Lazy: Miki is incredibly talented, and was able to memorize an entire dance routine after seeing Makoto perform it once. Problem is, she channels most of her energy into sleeping and munching on snacks.
- Buxom Is Better: Seems to think that, to the point that her self-introduction in the anime involves saying her name (in her sleep) and pointing out that she has a big chest.
- Clingy Jealous Girl: A mild one in the anime's second half.
- Is entirely this at the end of Azusa's route in Missing Moon.
- Cover Version: Has covered "sugar sweet nightmare" from Bakemonogatari, "Tips Tap Tip" from Eureka Seven, "Namida no Hurricane" from Get Backers, and "Catch You Catch Me" from Cardcaptor Sakura.
- Disproportionate Retribution: The real reason she joined 961 in SP games is because President Takagi ate her onigiri.
- Everyone Loves Blondes: While Chihaya is demonstrated to be the best singer and Azusa is considered sexier, Miki is often portrayed as the 765 Pro idol who has the charisma in getting the most fans to like her.
- Expository Hairstyle Change: In iM@S2, her hair is is wavier, and blonde has become her real hair color as opposed to just a dye.
- Freak Out: In her alternate route, she absentmindedly walks into traffic, and the Producer pushes her away at the last second. He is hospitalized, and Miki, realizing how her inattention caused a lot of trouble, decides it's high time she stop being lazy. In the anime however, Haruka is the one who brought the Producer's downfall, due to her own clumsiness.
- Friendly Enemy: During SP games, despite being in 961, she showed almost zero hostility towards 765 Pro idols.
- Hair of Gold, Heart of Gold: For the most part. Her selfish side can sometimes strain it though.
- Dumb Blonde: For Puchim@s!.
- Idiot Hair
- Image Song: "relations", "Furufuru Future", "Shocking na Kare", "Day of the future", "Marionette no Kokoro", "Nostalgia" (main series), "Tsuioku no Sand Glass", "FAKE SELF×TRUE SELF" (Million Live), "Closet Fashion Lover", and "Champion" (Puchimas)
- Important Haircut: In the Xbox 360's alternate route, she cuts her hair and stops bleaching it.
- I Owe You My Life: In her alternate route (see Freak Out) she falls in love with the Producer.
- It's All About Me: Very self engaged.
- The Kirk: When she was with Project Fairy, she was this to Takane's Spock and Hibiki's McCoy.
- The Nicknamer: Not as much as Mami and Ami, but she does have nicknames for a few people; "Makoto-kun" for Makoto, "Forehead" for Iori, and from episode 14 of the anime onward, she calls the Producer "honey". For some odd reason she addresses Ritsuko as "Ritsuko...san", always pausing before the honorific.
- Relationship Sabotage: Played with in SP Missing Moon. In Azusa's case, after she rejoined 765 Pro, she couldn't stand Azusa being in a relationship with Producer, and wanted to get in their way. In Chihaya's case, she keeps meddling Chihaya, asking whether she likes the Producer.
- Sinister Scythe: Her Weapon of Choice in Nemuri Hime movie.
- Sleepyhead: If she's not the character currently in focus, chances are she's in the background sleeping.
- Smitten Teenage Girl: Both in The iDOLM@STER 2 and a mild one in the anime, most apparent in her alternate route in the first game.
- Spoiled Brat
- Third-Person Person: Done to make herself sound cuter.
- Trademark Favorite Food : "Onigiri na no!!"
- Verbal Tic: "-na no" (a declarative phrase) and "Afu~" (Japanese onomatopoeia for yawning)
An energetic 15-year-old from Okinawa who loves to dance and sing. She became an idol to make people happy, and has a ridiculous number of pets ranging from the mundane to the bizarrely exotic. Hibiki was introduced in the iM@S SP as a member of Project Fairy, 961's production. In iM@S2, she is a part of 765 Production.
- Affably Evil: During her time at Project Fairy.
- Book Dumb: When asked about her grades in school, she uncomfortably dodges the question but insists she's really good at PE.
- Conspicuous Trenchcoat: Disguises herself like Haruka and Makoto above, to the point where Kotori doesn't even recognize her.
- Cover Version: Has covered:
- Cute Little Fangs: In the 2011 anime.
- Depending on the Artist: Shrunken, inconsistent B-W-H sizes aside, her breast size varies heavily depending on the artist (ranging from outright flat with no definition to sizable with lots of cleavage), as does her skin tone.
- Does Not Like Shoes: She wears sandals far more often than any other Idol, whether it be casual or in an outfit. And likewise, if any girl has her shoes off and wandering about barefoot, it's more than likely her. Even when playing sports in proper uniforms, she prefers sandals over sneakers and socks, though she isn't completely averse to them.
- A Dog Named "Dog": Played with; a majority of her animals have a cute nickname with the name of their species name in them, like Hamuzounote and Inuminote .
- Eyes Always Shut: Not during regular conversation, but in the PSP game she spends large portions of her songs with her eyes closed when no other girl does that.
- Fluffy Tamer: Befriended a shark in episode 26 and even gave it a nickname.
- Friend to All Living Things: She has dozens of pets, ranging from the mundane (cat, hamster, dog) to the exotic and outright bizarre (a crocodile!).
- Genki Girl
- Gullible Lemmings: She believes all of the lies Kuroi told her about 765.
- Horrible Judge of Character: She's quick to believe anything she's told. This is why she's so antagonistic towards the Producer in the SP games. She almost gets seriously screwed over in the 2011 anime by Kuroi's interference.
- The Idiot from Osaka: She's from Okinawa, but otherwise fits.
- Image Song: "Next Life", "TRIAL DANCE", "Brand New Day", "Pon De Beach" (main series), "Rebellion", "smiley days" (Million Live), "Shiawase no Recipe", and "Ten to Umi no Shima" (Puchimas).
- I'm Taking Her Home with Me!: To Yayoi. In Puchim@s, she almost succeeds.
- Jerkass Façade
- The McCoy: When she was with Project Fairy, she was this to Miki's Kirk and Takane's Spock.
- The Rival: During her time at Project Fairy.
- Serious Business: She takes her rivalries very seriously.
- Speaks Fluent Animal: While she speaks to animals in a cutesy fashion, in the anime, she can understand what her pets are saying. In One For All one of her communications show her having a conversation with Hamuzou (who's offscreen).
- Take That!: Her hatred of 765 Pro in the PSP game stems from her belief that 765 is a corrupt perverse agency that sexually harasses its talent. Given the shenanigans that often occur in touch communications...
- Tan Lines
- Tomboy: Subtler than Makoto, but still apparent.
- Trash Talk
- Wild Child
An elegant and majestic 17-year-old from an unstated, far-off land, Takane was first introduced as a member of Project Fairy in iM@S SP. Her distance can be mistaken for haughtiness, but she's very polite to everyone, even her rivals. In iM@S2, she is a part of 765 Production.
- Arranged Marriage: In iM@S2. Perhaps even the Bureaucratically Arranged Marriage variety, depending on her true origin. The Producer helps avert it.
- The trial to avert it results in Takane falling for the Producer and she henceforth addresses him as if she was his wife.
- Big Bad: Her character in the Nemuri Hime.
- Big Eater: In one episode of the anime, she ate three large bowls of ramen. In one sitting.
- In addition, in her segment of "Live?! On Sundays". Takane's Ramen Expedition, she devours a truly intimidating bowl of ramen singlehandedly. And later proceeds to devour both of the twins' equally intimidating helpings. "Gluttonous Princess", indeed.
- And then in the OVA, she eats enough at a revolving sushi restaurant to make Touma think nothing's coming along the conveyor. Probably the only time she intentionally devoured so much out of pettiness, since she and Touma had just finished an argument.
- Takane doesn't restrict herself to Japanese food either: during the screening of Azusa's movie, while the other girls are tearing up, she's eating popcorn - out of a huge bucket - in fistfuls.
- Blind Mistake: In the anime, where she mistakes a billboard for somebody waving at her. If she wore glasses in the first place, she'd certainly qualify for Blind Without 'Em.
- Boobs of Steel: Is very nearly the bustiest character in the team (Azusa has her beat by one centimeter) and is shown to be able to effortlessly and gracefully throw around a man far bigger than her who was just mentioned to be a judo black belt.
- Breaking the Fourth Wall: In Puchim@s she knows about the readers and makes comments or gestures towards them. Other idols who witness this are confused about who she's talking to.
- But Not Too Foreign: She's stated as being half-European.
- Cloudcuckoolander: Although Takane usually just comes off as mysterious and elegant, she occasionally has her "Uhh... Takane?" moments. For instance, during the Ribbit Ribbit cooking show she developed a more than strange attachment to the head of her frog costume. The Producer had to remind her that, no, she was not allowed to take it home. In Puchim@s, her strangeness is taken Up to Eleven.
- Cover Version: She's covered Cutey Honey's iconic titular song, "Tamashii no Refrain" from Neon Genesis Evangelion and "staple stable" from Bakemonogatari.
- Elegant Gothic Lolita: A few of her exclusive costumes, and some of her casual wear in the anime. Even in the summer Takane's wardrobe emphasizes elegance.
- Friend to All Children: For all her distant behavior, she can be incredibly warm with kids. Sometimes acts as a Cool Big Sis to Ami and Mami.
- Foil: To Iori Minase. Both are ojous but Iori's of the bratty variety and is short, ill-tempered, flat-chested, and acts polite to strangers but mean to people who personally know her, whilst Takane's of the Proper Lady variety and is tall, well-endowed, and is polite to everyone, even her rivals.
- Genius Ditz: Is so airheaded and weird one has to wonder whether she has some kind of condition... that is, until she turns out to speak nearly a dozen languages (which is even more impressive in the overwhelmingly monolingual Japan), be a judo master, and possess a mind-boggling wealth of the oddest trivial knowledge.
- Gentle Giant: Takane is officially the tallest of the 765 Production idols; the Cinderella Girls game introduces Kirari Moroboshi, who is a whopping 185 cm tall.
- Punny Name: Her first name is phonetically similar to the Japanese phrase "So tall" (if read as 'Taka, ne') or the word for mountain peak.
- Gratuitous English: In the anime. "That's top secret."
- Happily Adopted: She seems more or less fine with her adoptive family.
- Hidden Buxom: Usually covers her chest with heavy clothing. When she changes into her swimsuit at the beach, she makes Chihaya visibly envious.
- Hair Decorations: Is almost always seen with an Alice band in her hair.
- Hime Cut: Mixed in with Ojou Ringlets, although her hair is somewhat wavier than typical examples.
- Human Aliens: She just might be one, given the various hints that she's from the moon.
- Image Song: "Flower Girl", "Kazahana", "Futatsu no Tsuki" (main series), "Koibana", "addicted" (Million Live), "Princess Snow White", and "Tsuki no Sakura" (Puchimas).
- I'm Taking Her Home with Me!: To most of the Puchidols.
- Keigo: Indicates that she is excessively formal.
- Watakushi when refering to herself and Anata-sama for the Producer towards the end of her route.
- Lady of War: Her character in the second Idol movie seems to be this.
- Lonely Rich Kid
- Maybe Magic, Maybe Mundane: She's most likely either from the moon or from Germany, and the series deliberately feeds hints toward either direction.
- Mundane Object Amazement: Takane is simply entranced with the revolving sushi restaurant in Episode 26 of the anime, among other instances.
- Mystical White Hair: Given her indeterminate origins.
- Nice Girl: Distantness aside, she's very polite to everyone, even to her rivals.
- The Ojou: Comes from a family so wealthy she carries a black credit card. A more proper-lady sort of ojou compared to Iori, with some naivete.
- Omniglot: She's fluent in almost all languages related to Latin.
- Parental Abandonment: Sorta.....as mentioned above, she's Happily Adopted by the Shijou family and according to her profile, she hasn't been in contact with her birth parents in quite some time, not that she minds as she has a good relationship with her adoptive parents.
- Red Baron: She has "The Silver Queen" as one in multiple properties.
- Renaissance Woman: Let's see a judo master, a genius who rivals that of Ritsuko's, a polyglot, and is knowledgeable in a multitude of things most people would find trivial.
- Rich in Dollars, Poor in Sense: On occasion she shows surprising ignorance about typical things a middle-class lifestyle experiences regularly (like supermarkets and vending machines). Whenever she needs to pay for something, Takane reveals she carries a black credit card, the color traditionally meaning it has unlimited spending and offers special perks to the carrier at elite shopping locations.
- The Rival: During her time at Project Fairy.
- Shrouded in Myth: In-universe, she's this to her fans and even somewhat to her fellow idols.
- The Spock: When she was with Project Fairy, she was this to Miki's Kirk and Hibiki's McCoy.
- Statuesque Stunner: She's the tallest of the 765 Idols.
- Sugar-and-Ice Personality: Her distantness can be mistaken as being haughty, but she's far nicer than she seems.
- Trademark Favorite Food: Ramen, specifically the soup broth. She doesn't particularly care for the noodles, but eats them because it would be disrespectful to waste food. Due to her eccentric raising, she's likely to be unaware of bullion cubes.
- White Hair, Black Heart: Her character in the Nemuri Hime movie. She was willing to sacrifice Azusa's character, her own sister, for evil intent.
- Why Did It Have to Be Snakes?: Hibiki admits, when the two are looking for her snake Hebika in SP, that Takane doesn't like them. In the Mana manga, when visiting Hibiki, she outright faints when the snake is coiled around her shoulders.
- Wise Beyond Their Years: She's quite philosophical and can offer insightful thoughts.
876 Production IdolsAn idol stable exclusive to the Dearly Stars game.
- Cameo: The main trio makes a brief appearance in the main anime's tenth episode. They even get to sing the ending theme. They appear again during episode 25, and can also be seen briefly in the credits for episode 18.
- In Cinderella Girls, the group is playable for a Valentine's Day event.
- In SideM, Ai and Eri show up in one of Ryo's cards when he comes to hang out. The anime has Ryo himself cameo in his Cute and Girly costume, as he hasn't debuted as a male idol yet in that continuity.
- Color-Coded Characters: Just like their 765 counterparts.
- Demoted to Extra: They haven't done very much since their debut appearance besides cameos in DLC packs and rival festivals in the main games. Ryo has since become a main idol in SideM, but poor Ai and Eri have yet to appear anywhere outside of the ocassional Cinderella Girls card.
- True Companions
13-year-old daughter of Mai, herself a once hugely popular idol. Growing up on tales of her mother's glory, little wonder she ended up wanting to become an idol herself. Unfortunately, she fails every audition she tries, until a chance meeting with Haruka, who felt she has potential and introduces her to 876.
- Ascended Fangirl
- Calling the Old Lady Out: Ai and Mai had a falling-out after the latter's comeback, and are rivals for several chapters of Ai's story.
- Cute Bruiser: She beats up Ryo more than once across the different stories.
- Expy: Of Haruka.
- Genki Girl
- Image Song: "ALIVE" and "Hanamaru"
- Inelegant Blubbering: Part of her friendship with Yukiho stems from both being prone to cry a lot. The difference is where Yukiho mostly whimpers, Ai sounds the foghorn.
- No Indoor Voice
- Stage Mom: A subtle case, but the tales of Ai's mother made her desperate for a moment in the spotlight.
- Stuck in Their Shadow: In-Universe, Ai fears this when her manager says she could become a big success just by namedropping her famous mother, saying she wants to become an idol based on her own ability. A fear which turns out to be entirely justified.
15-year-old Eri was a hikikomori and an internet celebrity known as "ELLIE". One day, however, she is scouted by a producer from 876 to become a real idol, a prospect Eri is naturally very nervous about.
- But Now I Must Go: The end of her story arc.
- Elegant Gothic Lolita: Her ELLIE persona was famous for this.
- Every Girl Is Cuter with Hair Decs: Her clip.
- Hollywood Nerd: Eri is surprisingly pretty and well-kempt for a hikikomori.
- Image Song: "Precog" and "Crossword"
- Kind Hearted Cat Lover
- Otaku: Eri frequently references video games and internet memes, in some cases outright quoting lines.
- Shrinking Violet
- Shy Blue-Haired Girl
A soft spoken 15-year-old boy and Ritsuko's cousin. Fed up with his lack of luck with girls and unwanted luck with boys, he asked Ritsuko for help in turning him into the kind of cool, handsome idol that women would love. She introduced him to 876, where he is promptly put into a frilly pink dress and pushed onstage in a desperate attempt to save a show after the actual performer is a no-show.
For his tropes as a member of 315 Production, see here.
- Boy Meets Girl
- Breakout Character: Of not only his home group, but of his home game as well. He's the only one that gets a continuation of his story, thanks to his appearances in SideM, and kept all of his game characterization to do it.
- Butt-Monkey: Ryo's story is one long Humiliation Conga leading up to the end.
- Several of Ryo's bad endings turn out rather miserably for him as well. Being found out and becoming a laughingstock doesn't seem so bad compared to the ending where he cracks under the pressure of maintaining his double life and actually begins to believe he is a girl.
- Catchphrase: Tends to say "Gyooooon!" whenever he's surprised or exasperated.
- Clark Kenting: Glasses on, Male. Glasses off, Female!
- Cutting Off the Branches: His presence in SideM occurs after his route in Dearly Stars. He told the truth about his gender and it can be implied that his career at least survived.
- Dragged into Drag: The start of his idol career - and his story at large - was when he was forced to crossdress in order to replace a no-show performer.
- Dude Looks Like a Lady: Ryo's boyishly soft face shape, fluffy bob cut and thin build make his Dragged into Drag act all the more plausible.
- Earn Your Happy Ending: In Ryo's absolute best ending, he still loses a fairly sizeable chunk of fans who felt betrayed by the lie. However, he retains a large fandom of guys either willing to make an exception or in it for the music, and also gains a new following of fans inspired by the courage it took for him to pursue his dream of performing as a male idol.
- He is featured in SideM as a bona-fide male idol, and his reason for being an idol is stated to be "...by not giving up on my own dreams, I can give strength to everyone's dreams."
- Even the Girls Want Her: Yumeko thinks Ryo has this effect on her, before finding out his little secret, to much relief on her part.
- Image Song: "Dazzling World" and "Himitsu no Sangoshou"
- In Touch with His Feminine Side: This is perhaps why he tends to be asked out by male classmates.
- Masculine Girl, Feminine Boy: They may both be wearing skirts, but Yumeko wears the pants during her and Ryo's rivalry in DS. In Neue Green, the trouble with his relationship with Makoto is figuring out who is wearing what.
- Ship Tease: With Makoto in the Neue Green manga. Initially he is mistaken about Makoto's gender and believes he has a gay crush on her, while Makoto is not yet informed of the truth about him and thinks Ryo is confessing a lesbian crush.
- Sweet on Polly Oliver: Due to the nature of his idol career, many of his male fans confess to loving him as he performs in his girl persona. It's only after he confesses in front of a large audience does it (in a good ending) evolve into Even the Guys Want Him.
- Tabloid Melodrama: He and Makoto are the target of one such magazine in an early chapter of his story.
- The Bus Came Back: After not appearing since Dearly Stars, except for small cameo roles that reused previously recorded songs, he finally got some new music in SideM.
- Unsettling Gender Reveal: Ryo does this to the entire nation of Japan. His popularity determines whether they love him anyway or laugh him off the stage. As of SideM, the Acceptance ending is canon to his story.
- Wholesome Crossdresser: Played with; he's unwilling, but he ultimately remains kind and caring both in and out of costume.
Other Dearly Star Idols
- The Cameo: She makes a small appearance in her younger years in Ayasake wa Koganeiro.
- The Rival: Hard to believe, but yes. She serves as her own daughter's rival for a good chunk of her route.
- Stacy's Mom: Mai is the mom in this case to Ai's Stacy.
- Teen Pregnancy: Mai was forced into retirement when she got pregnant at age 15 (and still at the peak of her career) with Ai. Fourteen years later, when now 29-year-old Mai decides to rejoin the business, she's understandably still very hot.
Ryo's fellow idol and rival in his storyline. Though she maintains an image of being cute and innocent, she uses incredibly dirty tactics to claw her way to the top, such as giving out candies that clog the vocal cords of her rivals, or sabotaging the stage so the other contestants screw up.
- Alpha Bitch
- Bitch in Sheep's Clothing
- Defrosting Ice Queen
- Demoted to Extra: Has a minor role in her debut game, then makes so few appearances afterward the best she can manage is a passing mention in SideM.
- Fangirl: Of Azusa, to the point of calling her sister.
- Karma Houdini
- Kick the Dog: She hates Yayoi's guts, even going so far as attempting to pull her candy trick and ruin a live show before Ryo intervenes.
- Pet the Dog: She has the decency to feel bad about it later, upon finding out about Yayoi's financial situation.
- The Rival
- Tsundere: For Ryo.
- Vitriolic Best Buds: Prior to her finding out Ryo's gender, the two develop an odd mixture of mutual hatred and friendship, and hang out together quite often.
- Wounded Gazelle Gambit: Her first line of defense when called out on cheating.
Cineria (real name Ayane Suzuki)
- Boy Band: And before SideM rolled around, they were the only one in the series.
- Darker and Edgier: The boys have a distinctly darker sound. Just compare "Alice or Guilty" to the girls' "The World Is All One" or "Shiny Smile". And then "Koi wo Hajimeyou" happened...
- Lighter and Softer: After "Koi wo Hajimeyou", the boys' music has become significantly more light-hearted, going for calmer, funkier sounds. It appears that after defecting from 961 Productions, the group is finding a lighter image.
- A Day in the Limelight: They have a more primary role in SideM. They also have an OVA, Episode of Jupiter, which explains what happens to them just after they defect from 961 all through their recruitment into 315 in the A1 anime's universe.
- Demoted to Extra: After 2, they mostly show up in the main games as cameos for rival festivals. Averted with SideM where they are a central focus, and are promoted as one of the two main trios.
- Even Evil Has Standards: Or at least "Hypercompetitive Idols with a Penchant for Serious Business". Once they learn how low Kuroi would stoop to ruin the innocent idols of 765 Pro, they decide to call it quits.
- HeelFace Turn: Started off as a trio of intimidating, borderline snobbish rivals to 765 Productions. After defecting from 961 and being hired by 315, the boys are shown to be much friendlier, especially towards 765 Productions.
- Graceful Loser: In the game, even after losing to the girls in the Idol Awards, the boys bear no ill will against them and congratulate them. Kuroi on the other hand...
- Jerkass: In the anime, as Haruka first witnessed. Or at least that's how they appear to be, no thanks to Kuroi manipulating them into thinking that 765's idols are "corrupt".
- Recycled Script: Their anime plotline has a lot of elements borrowed from the Project Fairy storyline in the SP games, and Kuroi fueling rivalry between idol groups with over-the-top stories of his own victimhood is one of those.
- Image Song: Alice or Guilty, Koi wo Hajimeyou, BRAND NEW FIELD, and Planet scape.
- Limited Wardrobe: Averted, at least compared to their SideM peers. They have three idol outfits; their 2 getup, their 315 duds, and a new, streamlined outfit that was introduced in SideM: Live on Stage! and used as their default outfits from then onwards. Their casual outfits are essentially unchanging however.
- Magnetic Hero: In SideM, they serve as the initial glue that bonded the idols to 315. Whether it was because the Producer took idols to their concerts as an example of what to be going forward, or whether it was because the idols themselves realized their calling from watching them (as it was in S.E.M.'s case), one cannot deny the influence that Jupiter had on all of its juniors in their new production company.
- The Mentor: The advantage of having them in 315 is that they can use their experience to elevate the other, less experienced idols of 315. Episode 8 of the SideM anime is a great example of this.
- Mr. Fanservice: They serve as the male eye-candy, but Hokuto takes the cake as he's a model.
- Screw the Money, I Have Rules!: Episode of Jupiter showed that they went with 315 because they were the only company that didn't talk about getting tons of money if they signed on.
- Three Successful Generations: Shouta is the carefree Youth, Touma is the headstrong Adult, and Hokuto is the wizened Elder.
- The Rival: Serve as this to 765. In the anime, Touma is more of a rival to the girls than his costars since they don't seem to care that much about beating them.
- Unwitting Pawn: To Kuroi, who has been manipulating them into thinking that the idols of 765 are "corrupt" and that they were to do everything to stop them. And in Episode 21, once they wisen up to what's actually happening, they are understandably pissed off and walk out on Kuroi.
17-year-old leader of Project Jupiter. A self-centered idol who takes idol work very seriously and dislikes people who are just in for the fun of it.
- Adorkable: The real personality under his grouchy, competitive facade; while this is hinted at in his dere moments, it's especially apparent towards the end of both the game and anime.
- An Aesop: He's a grumpy, overcompetitive guy whose teammates are much more laid back than him, and he's in a game about The Power of Friendship. Then he discovers his boss's underhanded tactics...
- Anime Hair
- Berserk Button:
- Being told they were only pawns by Kuroi prompts Touma to hit the president in the 2011 anime.
- An executive implying that Jupiter only got famous because of 961 Productions' influence in the SideM anime forces Hokuto and Shouta to hold Touma back before he reaches out to attack them, too.
- Determinator: In your first face-off against him (where the winner is the group who can draw the most spectators to their stage with their performance), Touma utterly destroys your group even after losing one speaker to an electrical surge.
- Embarrassing Nickname: Don't address him as "Amatou".
- Expy: Shares a lot of resemblances with Kratos Aurion, from another Bandai Namco Entertainment game.
- Fluffy Fashion Feathers: Has one on his belt.
- Guest Fighter: He and Shiki Iseya appear as bosses (and eventually playable characters) in Tales of Asteria for one collaboration event with SideM.
- Hair-Trigger Temper: He's about as easy to set off as a firecracker, when it comes down to teasing or hitting a nerve.
- HeelFace Turn: Went through this the most out of the Jupiter trio. When first met, Touma is a complete Jerkass who insults your idol unit at 765 for not taking their work seriously and using cheap, corrupt methods to get to the top, thanks to Kuroi's lies. After realizing the error of his ways, Touma becomes a much friendlier to 765 and even offers to push Producer's taxi that's on its way to the airport.
- Idiot Hair: Rivaling Miki and Ai's.
- Image Song: "BANGxBANG" and "HAPPYxHAPPY Meeting"
- Insufferable Genius: He has the skill to back up his arrogance, and does not like when said skill isn't acknowledged.
- It's All About Me
- Jerkass: Although after Character Development, he becomes more of a Jerk with a Heart of Gold.
- The Knights Who Say "Squee!": Touma was a fan of Yusuke and Kyousuke Aoi, who form the unit W, back when they were soccer stars— to the point of having their autograph on hand in Episode 8 of the SideM anime.
- Took a Level in Kindness: Touma obviously mellows out by the end of the game and in the 2011 anime. We see this to full effect in SideM.
- The McCoy: Between Hokuto's Kirk and Shouta's Spock.
- Missing Mom: According to a drama CD, his mother passed away when he was young.
- Real Men Cook: Loves to cook. He's apparently so good at it that they released his homemade curry recipe as a buyable product.
- Screw the Rules, I'm Doing What's Right!: After witnessing one too many sleazy tactics on Kuroi's part in the anime, Touma decides they can't keep their heads down and breaks it off to compete with 765 fairly.
- Serious Business: Idoling.
- Spanner in the Works: In Episode 19 he discovers Kuroi plotting to destroy Chihaya's career with a picture of her arguing with her mother over Yuu's grave. He angrily calls him out in Episode 20, and come next episode he, Hokuto and Shouta finally call it quits.
- Stop Having Fun Guy
- Trademark Favorite Food: According to drama CDs and the D@YS OF JUPITER manga, it's cream soda.
- Trash Talk
- Tsundere: He's not quite the tough guy he thinks he is. He gets flustered and tries to cover it up whenever this shows through. Lampshaded by Shouta.
- Why Did It Have To Be Takane?
An "eternally dangerous idol prince", 20-year-old Hokuto is another idol for Project Jupiter, and his hobbies include piano, violin and going on dates.
- Adorkable: His self-introduction consists solely of over-the-top pickup lines and attempts at flirting because he claims he only knows how to appeal to a female audience.
- Affably Evil: When he was with 961 Production.
- The Casanova: In the 2011 anime, he's attractive to an ostrich!
- The Face: Touma might be Jupiter's leader, but Hokuto's the one who tends to do much of the talking and diplomacy on behalf of the group. This, along with his age, is probably why he handled much of Jupiter's post-961 affairs in Episode of Jupiter.
- Fan Community Nicknames: Hokuto calls Jupiter's fans angel-chan-tachi/little angels fairly often, both in public and in private.
- Fashion Model: It's a given considering he's an idol, but it's his legitimate side job.
- Gratuitous Italian: "Ciao!" He uses this constantly, nearing Catchphrase levels.
- Hidden Depths: He studied business in college, which is rather handy for handling most of Jupiter's indie affairs.
- Image Song: "Kesshou ~Crystal Dust~" and "ROMANTIC SHAKER"
- The Kirk: Between Shouta's Spock and Touma's McCoy.
- Old Friend: In SideM, he's said to have attended the same college as Rui Maita. This is likely why Rui was able to invite Jupiter to S.E.M.'s old school's cultural festival, and in the anime, Hokuto made a point of attending S.E.M.'s first performance.
- Prince Charming: He is promoted as an "idol prince," and while not an actual prince, has the charming demeanor befitting one.
- Significant Birth Date: He's born on Valentine's Day. Surprisingly fitting for a good looking flirt.
- Team Dad: As the oldest of the group and the only fully fledged adult, he's usually the one that handles financial situations and tries to listen to his younger costars from an older standpoint. Carries over once the trio comes under the 315 brand.
An aptly named 14-year-old idol who takes a relaxed approach to his career.
- Expy: It's pretty hard not to notice his similarities with Iori.
- The Gadfly: Shouta enjoys deliberately saying things that cause Touma to become flustered.
- Image Song: "On Sunday" and "BACK FLIP☆EMOTION"
- Manipulative Bastard: Not really one of the more serious examples, but he does tend to fake crying to make other people give him free things.
- Peek-a-Bangs: In the D@YS OF JUPITER manga, he adapts this hairstyle in his outside disguise.
- The Slacker: While he isn't noticeably as bad about it as Brilliant, but Lazy Miki or NEET Anzu, one of his hobbies is taking naps, and he has tried to worm his way out of doing work he doesn't want to do via this method.
- The Spock: Between Hokuto's Kirk and Touma's McCoy.
A Festa opponent introduced in One For All, hyped as the strongest rival yet.
- Anime Hair: Possibly the most extreme example in the mainline games to date.
- Fashionable Asymmetry: With her heterochromia, her different-length gloves and singular stocking, she definitely shows this in the stage outfit she uses for Acceleration; while it's also present on her stage outfit for Ultimate Eyes, it's to a much lesser degree.
- Gender-Blender Name: "Leon" is the offical romanziation of her name, and this name is considered to be masculine in many countries.
- Image Song: Acceleration and Ultimate Eyes.
- Limited Wardrobe: Nobody has a large wardrobe for casual wear to begin with, but Leon has no casual wear. You will only ever see her wearing one stage outfit, two if you get the EX Episode DLC.
- Mismatched Eyes: Leon's left eye is blue, and her right magenta.
- Only One Name: All There in the Manual hints at Leon having a last name, but in the game proper, her last name - if she has one - is never mentioned.
- Rank Inflation: Her idol rank is simply known as "Over-ranked."
- The Rival: Though, as seen in the girls' extra routes, she's actually more of a Friendly Rival, since she gets along with most of the girls (Yukiho and Azusa notably) and never once shows any ill will towards them. Also, when Chihaya suffers a mental breakdown, she goes backstage to check on her, genuinely concerned.
- Took a Level in Jerkass / Out-of-Character Moment: In the final EX episode for Hibiki, she dismissed Hibiki's challenge and tells her that she isn't worthy of being a top idol. This is incredibly jarring, considering how up until then she treated her and other girls with respect (and got along very well with Yukiho.) She becomes friendly again in the end, though.
A new idol under 961 Pro introduced in Stella Stage.
- Cover Song: She has covers of Overmaster and Acceleration, songs sung by previous 961 Pro rival idols (Project Fairy and Leon respectively), as well as ToP!!!!!!!!!!!!!, the game's feature song. The last one is due to the fact that players can produce her as a Secret Character.
- Family Relationship Switcheroo: While she is initially thought of as yet another name in the list of idols 961 Pro has managed, it later turns out that Kuroi isn't just her boss, he's also her father.
- Gratuitous German: Being that she was raised in Austria, this is to be expected.
- Image Song: Blooming Star
- Like Father, Unlike Son: Despite being Kuroi's daughter, her personality is the complete opposite to his.
- Only One Name: She is only known simply as "Shika". It's likely that her last name is concealed to hide the fact that she is Kuroi's daughter.
- Secret Character: Unusually for a character with her role, players will be able to produce her as a idol.
- Spoiled Sweet: Despite her privileged upbringing as Kuroi's daughter, she's nothing but kind and pleasant to the Producer and his idols.
- You Gotta Have Blue Hair: Very pale green hair, to be exact.
765 Production Staff
The rookie producer of 765 controlled by the player. As an avatar of the player, he is voiceless, faceless, and nameless, known only as "Producer" to everyone. In the anime, he's still nameless, but is revealed to be a young man not much older than Azusa, with mild manners and a nondescript face. Dedicated, if occasionally overwhelmed, he works hard to get the idols under his care to stardom. He is much less hands-on than Ritsuko, acting more as a guiding and supportive figure than a boss.
- But Now I Must Go: Invoked during the endings of iM@S and iM@S2. Averted if the Producer returns or the idol finds him a year later.
- Butt-Monkey: Is this a little in the anime.
- Celibate Hero: Specifically the anime version, especially around Miki, since a romantic affair could create scandalous negative publicity and ruin an idol's career. The game version does not follow this trope, since certain characters have love confessions in their story routes (Azusa and Takane for example).
- Covert Pervert: In most cases, the anime version of the Producer maintains a professional air around the idols. However the anime episode from Shiny Festa: Harmonic Score/Honey Sound has a scene with bikini clad Azusa approaching the Producer with unintentional disregard to personal space. The Producer quickly backs away and stops her from closer contact, but can't avoid giving a leering expression at her body for a second. Haruka witnesses the entire event and calls him out on it.
- Cover Version: Has covered Kobukuro's "Yell ~yell~" and Ulfuls' "Ashita ga Aru sa (Georgia de Ikimashou hen)".
- There's Fridge Brilliance in this. Many music producers have professional talent or were once successful artists. Despite his importance and frequent appearance in iM@S, nothing is known of the Producer's personal life or history.
- Crouching Moron, Hidden Badass: How he is portrayed in the Drama CDs.
- Cry into Chest: The idols are prone to do this to him in the games.
- Depending on the Artist: Those series which actually show him have rather different takes on his looks. In the manga The Idolm@ster Relations he is tall and slim but otherwise an ordinary office worker. In the manga The Idolm@ster 2: The World Is All One!! he is of more ordinary height but doesn't use glasses until after Chapter 20. In the anime series he could go for an older version of Keitaro Urashima or Yuuto Ayase.
- The Destined One: He is the one Azusa has been searching for.
- Determinator: For an idol under his care. He will not rest until she has achieved the musical acclaim she deserves.
- Everyone Calls Him "Barkeep": Or some other name-avoiding title.
- Expy: His anime version is one of Koichi Minamoto, but now caring for 13 girls instead of three!
- The Faceless: Until the anime came along. Still a very nondescript face though.
- Featureless Protagonist: His game incarnations for the most part.
- Heroic Sacrifice: He will not hesitate, even for a moment, to put his life in danger to protect the idols from harm.
- He Who Must Not Be Heard: In the game.
- Job Title: He is the one. He will become the Idolmaster.
- Knowledge Broker: To various degrees, as required for someone who's a record producer. His proficiency level at it varies from incarnation to incarnation.
- The Main Characters Do Everything: The Producer is the music producer for 765 Pro... but also a book manager, road manger, talent manager, tour manager, promoter, and even occassional psychologist. He does all the administrative tasks except for paying everything, which are the duties of the executive producer, President Takagi.
- Megane: In the anime adaptation and several manga adaptations.
- Nice Guy: In the anime version, which earned him a Fan Nickname, "Broducer".
- Office Romance: With the various idols through all the different media. Oddly enough, never with Kotori though.
- Player Character: In the games.
- The Promise: Has several with the various idols. Being able to keep his word is one of the factors that earns their undying trust.
- Ship Tease: With the various idols he interacts with. Specially Miki.
- The attraction is largely one sided from Miki and not actively reciprocated by the Producer. The anime episode from Shiny Festa: Melodic Disc/Groovy Tune also indicate that Yukiho, Makoto, and Takane have good chemistry with him... much to Miki's concern.
- Single Woman Seeks Good Man: The idols having romantic feelings for him. A common theme is that the Producer always believes in the inner strength and hidden talent of an idol, even when she feels it's lacking or not there. When she eventually overcomes the challenge, the idol realizes his support is unwavering, no matter how high she climbs or how far she falls.
- We Do the Impossible: Any idol under his wing will become successful. It doesn't matter how stacked the odds, the obscurity of the idol-to-be, or limited the accessible resources: he will make it happen.
- Workaholic: He does not appear to have any hobbies or a social life outside of supporting the idols under his care. Fortunately they are quite aware of this, and his devotion to them is genuinely reciprocated.
Secretary of 765 Production, who serves as the game's announcer and tutorial guide. Famous for daydreaming on the job — sometimes in the middle of conversations.
In the anime, it was revealed that she was an ex-idol under the tutelage of Takagi and Kuroi before their falling-out.
- A Day in the Limelight: Although not an idol, she sometimes gets a song in the larger album collections. This turns out to be a foreshadowing of her past as an idol. She got a manga, Asayake no Koganeiro, that elaborated on her past.
- Beauty Mark: She has one on the side of her mouth.
- Christmas Cake: It's strongly hinted that this bothers her (see Age, above).
- Exposition Fairy
- First-Name Basis: Subverted in iM@S2. Upon her self-introduction, she suggests the Producer call her either "Kotori-san", "Kotori-neesan", or "Kotori-chan". However, he decides to use "Otonashi-san" instead.
- Forgetful Jones: One of her traits in Puchim@s!, making PiyoPiyo a vital presence for office work.
- Idol Singer: She used to be.
- Image Song: "Sora", "Hana", "Hikari", "Sachi", "Yasashisa ni Tsutsumareta Nara", and "Kimi ga Erabu Michi".
- Just Friends: In every incarnation of iM@S media she is featured in, Kotori is unattainable for the Producer to support as an idol. She never interacts with the Producer on a personal level, so there's never chemistry between them. While she is featured in special Drama CDs, Bandai Namco Entertainment has not released an official manga, sidegame, or DLC that features Kotori as winnable.
- In One For All, on the other hand, she does try to ask the Producer out for dinner, and is extremely disappointed when he turns out to be busy. (Sadly, the player isn't given the option to accept her invitation.)
- Little Black Dress: When she sings in Episode 21, she wears this, and looks great in it.
- Mama Bear: Towards PiyoPiyo.
- Meaningful Name / Punny Name: Her name literally means "soundless little bird", which was an allusion to her not being an idol when the franchise was started. As the years progressed and fans made demands for her, she became an unofficial one.
- Mission Control: Her first appearance in Live For You was this for the player.
- Missing Mom: Kotori never really knew her mother growing up, since she passed away when she was a child.
- Ms. Imagination: Prone to having manga-styled Imagine Spots about whatever interesting events are unfolding before her. And she ups it when she gets caught:(Breaks into a teary, melodramatic Girly Run) "No, don't do it, Kotori!"
- Nom de Mom: Kotori shares her mother's maiden name after her father divorced her, since he couldn't deal with her being an Ill Girl.
- Out of Focus: Doesn't spend a lot of time with the idols in the anime. She lampshades it a good deal too, since she sometimes mentions how lonely it gets in the office.
- Sexy Secretary
- Shipper on Deck: In the anime, she seems to be very fixated on the idea of Makoto/Yukiho... She also briefly considered Takagi/Yoshizawa after seeing how close they are.
- Strong Family Resemblance: As shown in Chapter 3 of Asayake no Koganeiro, she looked almost exactly like her mother did when she was a teenager.
- Workaholic: Even when she's off work, Kotori is doing something work related, like watching the idols on television.
- Yuri Fan: In the anime. Has a couple shades of Yaoi Fangirl to match in episode 26.
- Zettai Ryouiki
President of 765 Production. Appears only as a black silhouette from the neck down. In the iM@S SP games, he has a fairly major role in the story... but still appears only as a black silhouette. Everyone refers to him as "President", so it's easy to forget his name.
- Benevolent Boss: He's generally depicted in this way...
- Mission Control: In the Xbox version of the game, he's the one who gives the player information on the current trends and idol rank every week.
- Put on a Bus: In iM@S2 his cousin Junijirou becomes president, while Junichiro becomes chairman as to avoid traveling all over the country.
- Though the change could have been prompted by his voice actor's sudden death before he could do any more voicework. This may also be the reason he does not appear in the Puchim@s anime adaptation which uses the poor Producer in his gags.
- Stupid Boss: Got handed the Idiot Ball for the iM@S SP games.
New president of 765 Production after his cousin Junichiro stepped down. In the anime, his body can now be seen in full, but his face is still obscured. Like Junichiro, he is referred to by everyone as "President".
- Ascended Extra: Bumps up to main character status in Asayake wa Koganeiro.
- Benevolent Boss: Nothing makes him happier than seeing his idols growing stronger and happy.
- Connected All Along: Takagi was not only Kotori's producer, but also her mother's. It's this connection that made Kotori want to become an idol under him.
- He Who Must Not Be Seen
- The Faceless: In the anime. Asayake No Koganeiro averts it since it's taking place during his younger years.
- My Greatest Failure: His inability to help Kotomi Otonashi reach stardom hit him hard, and he was still reeling from it when he eventually met her daughter.
- Passing the Torch: His position was passed onto him by his cousin.
- Status Quo Is God: Thanks to the Producer and the idols, at the conclusion of the anime, the bank accounts for 765 Production were full of cash. Junjiro used the money to purchase the company a massive corporate headquarters beyond their wildest dreams. Unfortunately the previous property owner was Kuroi, who pulled a bankruptcy scam and took 765Pro's mortgage payment without them being able to keep the building. Thus the group remain at square one, in the same rundown office they started in, despite being national celebrities.
- We Used to Be Friends: With Kuroi.
961 Production Staff
The president of 961 Production, first introduced in Idolm@ster SP.
- Adaptational Villainy: Kuroi is already a big Jerkass in the games, but in the anime, we see him doing much more dangerous slanders than just spreading rumors. This culminates in the slandering of Chihaya's past, which traumatizes the poor girl and disgusts the Jupiter boys.
- A Day in the Limelight: Asayake no Koganeiro shows off the relationship between him and Junjirou during the time they took in Kotori.
- Bad Boss: Towards his idols that are featured in-series.
- Big Bad: Arguably, of the series as a whole. If there is something fishy going on involving 765 Productions, chances are it's all Kuroi's doing.
- Consummate Liar: One of his deceptions includes giving Hibiki a larger B-W-H than she really has (which was revealed by iM@S2). In a more general sense, he's known to feed the idols under his charge defamatory lies about 765 Pro and its idols in order to make them think negatively about the other company.
- Corrupt Corporate Executive: Lies, cheats, and all-around uses dirty tactics to bring his idols to the top. Subverted to the in-universe public, seeing as how Kuroi is still a successful businessman and his production company is one of the most well-known in all of Japan.
- Dark Is Evil: He wears black, as if Kuroi isn't already an indicator.
- Dirty Old Man
- Evil Counterpart: To the Producer and President Takagi.
- Evil Is Petty: Boy howdy is he petty. He tries to ruin the lives of several hard working idols all because he had a fallout with their boss decades ago. Especially how he handles it: butting them out of magazine covers, attempting to get them fired off their own shows, and hiring paparazzi to possibly get some dirt is a little excessive for a studio he considers "third rate". Special mention goes to letting 765 purchase a new office building to move into, then bankrupting the company that owns the place the moment they put their money into it while he drives away cackling like a madman on the news.
- Gratuitous French: In SP, he likes peppering his sentences with French words like "Non", "Oui", etc. Would've been a French Jerk if he wasn't Japanese at all.
- Hate Sink:
- He Who Must Not Be Seen: In the games. He upgrades to The Faceless in the anime.
- Hoist by His Own Petard: His attempt to sabotage Chihaya's performance of Nemurihime by convincing the sound technician to cut out the background music backfires on him when Chihaya decides to sing acappella instead, prompting the technician to put the music back on for the second chorus. This achieves a greater effect on the audience than compared to if he did not try to sabotage the performance in the first place.
- Jerkass: Very much likes giving rumors and lies and slanders about 765 Pro... why? Just because he wants to feel superior over Takagi.
- Karma Houdini: In the anime, for all of his constant dog-kicking, he manages get the last laugh as his last scheme against the 765Pro Agency (by having the company building 765's new offices, which is under his ownership, declare bankruptcy) works wonderfully and they can't do anything to get back at him. He did lose his Project Jupiter, who's sick of his sabotaging, especially that one event involving slandering Chihaya with her Dark and Troubled Past to the point of traumatizing her, but considering that in his last words, he said that the Jupiters are expendable and he can find another group, it's only a matter of time until he rises back up to try and slander 765Pro again.
- Kick the Dog: Likes to revel in this sometimes. From exposing Chihaya's Dark and Troubled Past to all of Japan to making Karen Shinomiya cry in public and laugh at her face for it.
- Manipulative Bastard: To Project Fairy in iM@S SP, and Jupiter in iM@S2.
- Meaningful Name: Kuroi can be broken down into Ku-Ro-I, which corresponds to 9-6-1. Kuroi also means "black".
- Narcissist: Oooh boy.
- Pet the Dog: A dishonest manipulator he may be, but one SP radio drama reveals a (somehow) nicer side, when he takes a "family-like" photo of Azusa, Iori and Producer, and gives it to them to keep as a memorial/gift.
- Pitiful Worms: One of his ways to insult the people of 765 Productions.
- "The Reason You Suck" Speech: In iM@S2, during the Idol Academy nominations party, he harshly insults the Producer and your unit. Cue the Shut Up, Hannibal! from your unit's leader.
- Shut Up, Kirk!: He and Junijiro drink together during Episode 20. When Junjiro talks to him about letting the younger generation holding the reins for once, Kuroi outright dismisses it and bails after leaving tab.
- Smart People Play Chess: Confusing in that while he is a Manipulative Bastard, his formations in the board games he plays in the anime are always a huge "X".
- We Used to Be Friends: With Junijiro.
876 Production Staff
The president of 876 Production. An old friend with Junichiro.
- Benevolent Boss
- Idiot Hair
- She Who Must Not Be Seen: Like the other president, she only appears as a silhouette in the game.
A freelance producer who brings Eri to the idol industry.
- Given Name Reveal: Only in the SideM anime adaptation do we learn his first name, Mitsuaki. It serves as a Freeze-Frame Bonus, since it only appears on a business card before cutting away.
- Old Friend: To President Junjiro.
- Once a Season: There won't be an adaptation of an IM@S game that doesn't somehow have Yoshizawa in it. He usually appears once to interview a given group.
- Secret Keeper:
- Offers to not share the information on how Jupiter left 961 when he interviews them in Episode of Jupiter. The only reason he's told the story is because he's known them so long that he wants to understand out of personal concern.
- Also keeps mum about Kotomi's pregnancy when he discovers her after the Incident.
- Everygirl: She was described as the kind of girl that didn't turn heads one way or the other, and lacked individuality. However, that kind of blank slate personality endeared her to Takagi, since he looked at it as a way to cultivate her idol image from the ground up.
- Idol Singer: In her teens. Eventually, she ended up running away from the stage.
- Ill Girl: Kotori described her as being "in and out of the hospital" by the time she was married, which eventually led to her divorce.
- Posthumous Character: Long dead in the main series, and in Asayake wa Koganeiro she's been dead since Kotori's childhood.
- Ship Tease: Had some with Takagi when she was an idol.
- Strong Family Resemblance: In her youth, she looked exactly like her daughter save for the placement of her Beauty Mark.
- Teen Pregnancy: Barely eked out at 18-19 when she had Kotori.
