Characters: THE iDOLM@STER: Cinderella Girls
aka: The Idolmaster-Cinderella Girls
Characters originating from THE iDOLM@STER: Cinderella Girls. Originally a mobile device card game, it contains the largest iM@S cast: over 180 exclusive characters and growing. The property successfully expanded into other merchandise markets, foremost being Drama CD, Manga, and Image Song multimedia. Should not be confused with the other iM@S mobile game, which would be Dueling Games if they weren't from the same company.

     In General 

Cinderella Girls provides examples of:

  • Age-Inappropriate Dress: Some might call it fanservice.
  • And Your Reward Is Clothes: They boost an idol's performance and various card stats.
  • Art Evolution: Newer card illustrations are drawn better or with more complexity.
  • Asskicking Equals Authority: Musical stage battle idol style!
  • Bonus Boss: Random rival battles. However you will need to be at least in certain areas around Japan to face them.
  • Continuity Overlap: The 4-koma manga for Cinderella Girls implies the setting takes place after the original idols of 765 Pro have achieved celebrity status in Japan. Many of the idols are happy to perform the original cast's trademark songs or wear their unique wardrobe. It would also explain how 765 Pro has the resources to hire, promote and train so many idols at once.
    • Canon Welding: Further supporting the trope above, a character appearance in the ending credits of The Movie implies that Cinderella Girls and Million Live simultaneously occur in the future of the anime setting.
  • Card Battle Game
  • Costume Porn: Up to Eleven. It's been said Namco Bandai once hired fashion designers as advisers and it really shows.
  • Crossover: The original 765 Pro are featured in Cinderella Girls as already successful sempai the cast hopes to emulate. However the original idols are used very sparingly (limited edition or special event promotionals) and not eligable for vote during popularity polls. They're in Cinderella Girls, but techincally not considered among their official ranks.
    • Alternate Universe: Likely scenario with the Million Live cast. The two mobile games do not share their exclusive idols or even acknowledge they exist. The reason for this is because Million Live is a licensed under GREE and Cinderella Girls is a licensed under Mobage. They are competing companies who pay Namco Bandai to use the iM@S franchise.
  • Drama CD Dang It / Manga Dang It: You have to listen to their drama CD's or read the manga series, to get important information about the characters.
  • Early-Bird Cameo: 3 girls from the sixth batch of CG idols (26-30) were confirmed in an animated PV for Onegai Cinderella. From the Cool side we get Nao and Karen and from Passion, Syoko. Nina and Momoka were apparently replaced with Yuko and Sae.
    • Certain cards belonging to Chieri and Koume had their voices patched in before their CDs were released.
  • Free-Range Children: Not just all across Japan, but the entire world. The Producer sometimes travels along, but it's impossible for him to keep an eye on all of them at once. Some of the adult idols babysit as Cool Big Sis and Team Mom.
  • Hollywood Dateless: How this many beautiful girls and women are having trouble finding boyfriends or husbands. Averted once they become successful idols, upon which they have have thousands of devoted male fans, but the only man the idol wants at this point is the Producer.
  • Idol Singer: Goes without saying.
  • Is This Thing Still On?: A frequent happening during the Drama CD skits.
  • Job Title: The idols seek to become a Cinderella Girl: the title given to the most popular idol in the world. The Producer is obviously the Idolmaster.
  • Joshikousei: Too many to list.
  • Loads and Loads of Characters: Started with 100 idols. Currently around 180 as of late 2013.
    • Ditto Fighter: An unfortunate result of having so many characters. Many idols share the same core concept and only differ by age or how they apply the gimmick. For example, over a dozen idols use the bunny rabbit as their persona mascott. It usually falls on Fan-Art and Fanon to make greater distinction between the girls, but even that doesn't work for all of them because...
    • Put on a Bus: ...many of the idols are ignored when newer additions to the roster prove more popular. On the plus side, sometimes it allows fans to add more Fan-Art and Fanon to their personality. Occassionally the lack of attention might even rekindle the idol's popularity on contest polls. However this isn't a surefire guarantee since...
    • What Happened to the Mouse?: ...the less popular or unimaginative idols, tend to be abandoned and forgotten by Namco Bandai and game fans (i.e. don't get updated cards). Fridge Horror if one interprets this to mean the Producer could not make her career successful and the idol's dream never comes true.
  • Merchandise-Driven: It's probably easier to list what doesn't get merchandised. The official company stance is, "anything not made to intentionally harm." Therefore you won't see products packaged as Cinderella Girls weaponry or insecticide. However everything else from food to clothing to toys to pet supplies are perfectly valid and do exist.
  • Mobile Phone Game
  • Music for Courage
  • The Power of Friendship: Storyline cornerstone of character interaction in iM@S.
  • The Power of Love: An idol's affection has a factor in the game.
  • Reused Character Design: Several girls use similar, sometimes exact, themes in their character design. Some are even based on iM@S voice actress or inside jokes about the franchise. It's rumored Cinderella Girls incorporated rejected or unused development artwork from the original iDOLM@STER.
  • Schrödinger's Gun: Personality details and character quirks of the idols.
  • Theme Birthday: Using the Gregorian calendar, no two idols share the same birthday except for twins. Using this system, Namco Bandai is probably aiming for 366 heroines, meaning everyday would be an idol's birthday. At present the average is every other day is an idol's birthday.
  • Star-Making Role: Namco will splurge on a high profile VA every now and then, but many of the Cinderella Girls are voiced by complete unknowns and rookies.Depending on the viewer, this can be thought of as embodying the spirit of Cinderella Girls by giving newbie voice actors a chance to shine, or hiring the cheapest actors they can find.
  • There Are No Therapists: Quite a number of the idols should get professional counseling for their personality quirks.

Master Collection Idols

Cool Type Idols

Cute Type Idols

Passion Type Idols



While categorized under Passion Type, the Trainer sisters are collectively a fourth color set: the green cards. They are not actually idols, but trainers who teach them dance routines and staying in physical shape. Trainers have ridiculously low attack and defense stats, making them useless in card battles, but increase reward experience for the idols they accompany. Fans have noted that all four siblings, despite different height and measurements, claim the same weight. This leads to the ironic idea they are lying about it.

Secretary to the Producer of Cinderella Girls, and serves as the game's tutorial guide and information woman. She's essentually an Expy of Kotori Otonashi, and does not have an active idol career or in-game card.note 
  • Breakout Character: Despite not being a winnable idol or having an official card, she has been assigned a voice actress and got a Drama CD skit. Rumors of an Image Song are now abound.
  • Depending on the Artist: Because her vitals are unknown, Chihiro's physical appearance is somewhat variable. Some media present her as a woman just out of her teens, while others aim closer to a Christmas Cake. The outfits she wears can also alter the impression of her maturity and age.
  • Dodge the Bullet: In an unlockable minigame the Producer brings a watergun to work and tries to shoot Chihiro with it. She pulls this to avoid most of the shots. The goal of the minigame is to tire out Chihiro and hit her before running out of ammo.
  • Exposition Fairy
  • Expy: Of the main series Kotori Otonashi.
  • Gainaxing: When she does her jumping animation.
  • Genki Girl: Very upbeat and positive about things. Even if the Producer fails at a task, she's confident he will recover and succeed at it eventually. When really happy she can be extremely excitable and expressive.
  • Just Friends: Unattainable for the Producer to support as an idol.
    • Of course it doesn't prevent Ship Tease in the Yonkoma. For example, the Producer placing his suit jacket around an overworked Chihiro who falls asleep in the office.
  • Knowledge Broker: She runs the tutorial.
  • Mission Control: Gives out the Producer's mission objectives and game events.
  • Number Two: When the Producer isn't around she's in overall charge of the office and the idols respect her authority.
  • Out of Focus: Can't be voted for on official polls.
  • The Scrooge: The common fan explanation for her not giving the Producer game items for free.
  • Sexy Secretary: She's the Producer's secretary... and she's quite sexy.

     The Producer 

Traits unique to the Producer of Cinderella Girls:

  • The Ace: At being a music producer. He can turn social outcasts, the mentally unhinged, and street bums into superstar idols.
  • Balanced Harem: The 4-koma manga has been aiming for it.
  • Chick Magnet: All 180+ idols would do anything to be his girlfriend.
  • Cloudcuckoolander's Minder: A reason why Hilarity Ensues in many of the Drama CD skits, is because the Producer is absent from stopping the excentric idols from causing havoc or indulging in their unusual interests.
  • He Who Must Not Be Seen: The Yonkoma and most manga adaptions follow this plan. They have the Producer's face obscured by an object, an idol's body, cut off by the panel, or only show the back of his head.
  • Interpretative Character: It is generally accepted that the Producer of Cinderella Girls is the same from the iM@S2 continuity, though after 765 Pro has achieved financial success with the original 13 idols.
  • Not a Date: Idols will try to arrange time alone with the Producer, on the pretext of discussing plans for her music career, but spend the majority of the meeting to make romantic advances on him. Due to his Clueless Chick Magnet reaction to these attempts, the incidents become Flavor 2.
  • Office Romance: Their game card quotes highlight it.
  • Parental Substitute: Several idols have such a relationship.
  • Ship Tease: Each of the Image Song Drama CD focus on it for the idol in question.
  • This Is Your Song: Each idol is implied to be thinking of the Producer when singing her Image Song. A few call out to him in the lyrics.
  • The Voiceless: From time to time the Producer is featured in the radio show interviews of the idol's Drama CD. Just like Staff-san, he usually indicates approval or displeasure at the idol's comments with a sound emitting speaker. To differentiate him from Staff-san, the Producer's makes a lighter toned "pin pon" sound effect.
    • During Koume's Drama CD the Producer is the Zombie co-host. He uses unintelligible undead grunts with the sound effects.
  • Weirdness Magnet: The multitude of idols. Each has a unique persona or trait that defines her individuality from the others, many of them being highly unusual.
  • When You Coming Back, Producer?: The idols will loiter in the workplace, waiting for the Producer to return from his office assignments. They also get sad when he's too busy to attend their office parties or have fun with them.



Featured in the idol's Drama CD interviews, Staff-san is the radio show co-host who indicates approval or displeasure at the idol's comments with a sound-emitting speaker. The more eccentric idols tend to get the "negative buzz" a lot, causing hilarious reactions. In general, the idols have a strictly professional relationship with Staff-san, making him a non-romantic male character for them to interact with.

  • The Comically Serious: Best way to describe his personality.
  • Everyone Calls Him Barkeep: It's rather unlikely his real name is Staff-san.
  • He Who Must Not Be Seen: There isn't official artwork of him, face hidden or otherwise.
  • In-Series Nickname: Idols who constantly get the "negative buzz" call it the buu-buu speaker for the sound it makes.
  • Mission Control: Staff-san's overall purpose is to ensure the idols stay on topic during the radio show. He does not always succeed.
  • Not So Above It All: Some of the ad-lib challenges he gives to an idol are rather Trollish. For example, making Miku Maekawa pretend to be a puppy.
    • Could be Fridge Brilliance when you consider that an idol should expand her horizons and be comfortable with unfamiliar situations, despite the running theme that each Cinderella Girls idol is largely defined by their own quirk.
    • Outright confirmed in Nao's interview, where the following exchange occurs:
    Nao: Is it really so fun to tease me?
    Staff-san: *ding-do—BUZZBUZZBUZZBUZZ*
    Nao: Ahh, I heard that ding-dong just now! I won't forgive you if you make fun of me again!
    • The ending shows that it was actually Producer doing the interview, and Nao chases him out after one too many teasings.
  • Obstructive Bureaucrat: The idols who refuse to follow the script believe this. He's actually not. A secondary role for Staff-san, appears to be an authority figure the Cinderella Girls can openly disagree with or ignore, since they love and trust the Producer too much for that to happen to him. However it varies from idol to idol, since the nicest don't defy or get upset with Staff-san.
  • Out of Focus: Doesn't make an appearance in the sixth batch of CD drama interviews, being replaced by the Producer instead.
  • Talking with Signs: Whenever Staff-san wants to directly tell an idol something, he writes the message on a card. She will usually read aloud what's written on the card, so the listener can know. The idol will then either agree to the instruction or vocally reject it.
    • Shown Their Work: Studio crews using signs for silent communication happens in real radio and television shows that are live recordings (news networks for example). Modernized locations have replaced cardboard signs with electronic teleprompters, digital displays, and laptops.
  • The Voiceless: Never actually says anything.
