This is the list of characters from The Idolmaster game franchise.

The primary characters in The Idolmaster are affiliated with 765 Production, described as a small, independent talent agency based in a small office.^[1][2] In Million Live!, it is depicted as a much larger talent agency, even having its own theater.

Haruka Amami (天海 春香, Amami Haruka)

Voiced by: Eriko Nakamura

Million Live! archetype: Princess

Haruka is an all-around ordinary girl and is considered the face of The Idolmaster. She has enjoyed singing and baking sweets ever since she was a child, despite the fact that she seems to be quite inept as a cook in general. She is easily excited and somewhat clumsy, admitting that she habitually trips at least once. Despite that, she always tries to remain positive and keeps a strong resolve, always working the hardest to make the Producer happy. Even though her character image color is red, Haruka actually tends to be a bit partial towards the color magenta, if not pink, which is Iori’s image color. Haruka is best distinguished by the ribbon bows on her hair. Apart from her dream of becoming a famous idol, she’s very grounded in her roots and is comfortable just having work in general, as well as spending time with her fellow idols. Haruka is close to the other idols, but she is the closest to Chihaya Kisaragi, whom she helps overcome her past.

Chihaya Kisaragi (如月 千早, Kisaragi Chihaya)

Voiced by: Asami Imai

Million Live! archetype: Fairy

Cool and serious, Chihaya has the greatest enthusiasm towards music and the greatest natural talent of all of the girls, earnestly believing that if she were no longer able to sing, she would rather die. She does not very much care for the title "idol" though, preferring to refer to herself as a "vocalist" instead. Chihaya enjoys listening to classic music, and often spends her time all by herself, giving a nature of maturity around her, though she is really awkward when it comes to communicating with others. Despite her age, she has the smallest bust out of all of the characters and is very conscious of it whenever she sees other girls with bigger busts, especially Takane and Azusa. Chihaya has a tragic past, namely that she lost her younger brother to a car accident eight years ago, causing her to blame herself for whatever happened that time. This also led to her parents’ divorce, driving a wedge between her and her parents. She overcomes her past thanks to her friends, and after that whenever she comes to her friends, she is quite cheery, but still isn’t very expressive. Chihaya is the best friend of Haruka Amami.

Yukiho Hagiwara (萩原 雪歩, Hagiwara Yukiho)

Voiced by: Yurina Hase (2005–2010), Azumi Asakura (2010–present)

Million Live! archetype: Princess

A terrible crier, Yukiho aspires to become an idol in order to one day shed her cowardly disposition. She is afraid of dogs – even chihuahuas seem threatening to her – and does not do well with men either. Having grown up in a strict, traditional Japanese household, Yukiho’s drink of choice is tea, preferably green tea. Among her hobbies is poetry, especially writing haikus, but she is too shy to share her poems with anyone even once. Though her image color is white, she tends to be partial to the color "Baby Blue". Whenever she is depressed or scared, she has a habit of running off, exclaiming she will go "dig a hole and bury myself in it." Sometimes, she takes it literally, grabbing a shovel and digging a hole until someone tells her to stop. Yukiho is Makoto Kikuchi’s best friend since childhood.

In 2010, Yukiho’s original voice actress, then known as Yurika Ochiai, resigned from her role, citing death threats against her that also forced her to change her name. As a result, she was replaced by Azumi Asakura from The Idolmaster 2 onwards.

Yayoi Takatsuki (高槻 やよい, Takatsuki Yayoi)

Voiced by: Mayako Nigo

Million Live! archetype: Angel

Yayoi is a bright and cheerful girl who cares for her family very much. Due to her father’s occupational status uncertainty, her family is quite poor, as indicated by Yayoi’s plain clothing, which she has actually had for a very long time. To earn extra money, Yayoi often does cleaning and other odd jobs around the 765 Production office building, and continues to do so even after she debuts as an idol. Fittingly, she is highly energetic, never letting the weight of this world can discourage her. Yayoi is the oldest of six siblings and is often the one who looks after her siblings, but also wishes that she had an "older brother" type around to look after her. Yayoi is very close to Iori Minase, despite having vastly different backgrounds.

Ritsuko Akizuki (秋月 律子, Akizuki Ritsuko)

Voiced by: Naomi Wakabayashi

Million Live! archetype: Fairy

The cool, smart-girl type, Ritsuko believes in theory more than her own inner strength. Originally an intern working at 765 Production after graduating from high school, due to a lack of girls scouted by 765 Production, Ritsuko decided to become an idol herself. Ritsuko’s family consists of herself, her mother, and her father. Her parents share the same traits as Ritsuko – being business-like and hardworking. They also own a shop in the city. Despite being an idol, she still has one hand in the business side of her own celebrities’ life, and is quick to chide the Producer if she thinks he is not doing his job correctly.

In The Idolmaster 2, Ritsuko becomes the producer for the idol unit Ryūgū Komachi and ties her hair up. She’ll tie her hair in braids again when using a Ryūgū Komachi costume in the game. In the anime, she is a semi-active idol who became a producer for 765 Production, and ties her hair in braids for the concert in episode 18.

As of Platinum Stars, Ritsuko is now a semi-active idol in 765 Production.

Azusa Miura (三浦 あずさ, Miura Azusa)

Voiced by: Chiaki Takahashi

Million Live! archetype: Angel

The oldest amongst all idols in the game, Azusa’s personality is kind-hearted but an air-headed "big sister" type. She is very easygoing, but has an incredibly terrible sense of direction, which becomes subject of a running gag – whenever she is walking all by herself, she will end up in a strange, distant place, with no idea of how she got there or how to get back. Her air-headed personality is shown when she thought of Hibiki’s hamster as 'a valuable thing', making her attempt to put him inside an inn room safe. Azusa also enjoys giving and reading fortunes, and has a firm belief that she will one day fall in love with "someone destined for her". One of her motivations for becoming an idol is, in fact, to someday find her true love.

In The Idolmaster 2, Azusa cuts her hair short (which was originally long) and makes an idol unit with Iori and Ami called Ryūgū Komachi. In the anime, Azusa still has long hair at the beginning, but later cuts her hair short after she joins Ryūgū Komachi.

Iori Minase (水瀬 伊織, Minase Iori)

Voiced by: Rie Kugimiya

Million Live! archetype: Fairy

The daughter of one of the associates of the 765 Production president, Iori is a spoiled rich girl who flaunts her family’s wealth. Although she speaks quite politely and refined on stage and in public, she has a very sharp tongue and is quick to berate other people’s intelligence or attitude, especially the Producer. Probably because she was raised with two older brothers, Iori has grown up with a strong competitive streak, and thus rarely shows any weaknesses. However, she does have a much softer side that she shows from time to time, making her personality that of an archetypal tsundere character. She is sometimes seen carrying around a stuffed rabbit with her, which she named "Usa-chan" (also known as "Charles Donatello the 18th" in the anime). Despite being such a spoiled brat from a wealthy family, her best friend is Yayoi Takatsuki, who happens to be much poorer than her.

In The Idolmaster 2, Iori makes an idol unit with Ami and Azusa called Ryūgū Komachi. She also changes her hairstyle, leaving a bang of hair out of her hairband.

Makoto Kikuchi (菊地 真, Kikuchi Makoto)

Voiced by: Hiromi Hirata^[3]

Million Live! archetype: Princess

The tomboy of the group, Makoto is popularized as the "pretty-boy idol" within 765 Production. As a result, she has accumulated more female fans than male ones, becoming the cause of her psychological complex and a running gag at her expense. She is usually seen in sporty outfits and was already very popular among her fellow students at the all-girls school she attends, and her current work as an idol does not make the situation any easier for her. Her father is a famous race-car driver and had wished for a son instead, so he raised Makoto as a boy. Even though she is not ungrateful of her popularity, underneath her gruff, boyish exterior, Makoto is actually an honest, sensitive girl who wishes to make herself more feminine. Therefore, unbeknownst to her father, she decided to become an idol in order to find a way to a new, more feminine presence for herself and to show others that she can have a girly side as well. She is also shown to be friends with Yukiho Hagiwara, who is much different from her as far as personality is concerned.

As of The Idolmaster 2, Makoto grows her hair longer and parts her bangs in the middle, and she is also revealed to be a skilled mixed martial artist.

Ami Futami (双海 亜美, Futami Ami)

Voiced by: Asami Shimoda

Million Live! archetype: Angel

Ami and Mami are a pair of playful identical twin sisters who make a two-girl singing sensation. Ami and Mami both enjoy doing impressions and teasing their co-workers, though Ami is said to be more fun-loving than Mami. The only way to tell the two girls apart is through their hairstyles – Ami ties her hair to the right, Mami to the left – otherwise, they are identical. They use this to their advantage by switching their hairstyles and both performing as idols, but only underneath Ami’s name. In The Idolmaster arcade game, the only people who actually know that Ami and Mami are twins are fellow members of 765 Production.

By the time of The Idolmaster 2, the public has come to acknowledge the existence of the twins. As a result, Ami makes an idol unit with Iori and Azusa called Ryūgū Komachi. In the anime, the twins are already produced as separate idols.

Mami Futami (双海 真美, Futami Mami)

Voiced by: Asami Shimoda

Million Live! archetype: Angel

The other half of the Futami twins, Mami is available to produce as a solo idol from The Idolmaster 2 onwards. As the twin sister of Ami, Mami has many similarities to Ami in terms of personality, but is described as more mature and a little more obedient in comparison.

While the original arcade game implies that Ami is the older of the twins, the Xbox 360 game hints towards Mami being the older twin, which seems to have been the case since then. Also in The Idolmaster 2, Mami extends her ponytail longer to further differentiate herself from her sister, and she often worries that she doesn’t get as much work as Ami due to the time they spent as an idol under the same name.^[4]

Project Fairy is an idol unit introduced in The Idolmaster SP, produced by the rival 961 Production. The unit was specifically created so that its three members harmonize perfectly with each other, and have different specialties. As of The Idolmaster Dearly Stars, the members of Project Fairy have become part of 765 Production.^[5]

Miki Hoshii (星井 美希, Hoshii Miki)

Voiced by: Akiko Hasegawa^[6]

Million Live! archetype: Angel

Introduced in the Xbox 360 game, Miki is a natural, talented girl who feels that she has rarely had to work hard for anything. Because of this, she is pretty lazy and always approaches tasks with a very laid-back personality. She manages good grades with minimal effort and boasts natural good-looks that belie her age, but she can sometimes become an annoyance to others because of the quirky nature she sometimes exhibits. She even receives about 20 confessions of love from boys everyday. Raised in a very laissez-faire family, Miki’s parents don’t see any problem with her becoming an idol. While she doesn’t really have cruel intentions, she believes like everything else, she can make her way to become a top idol easily. Miki also loves onigiri, and can be seen sleeping all day when not doing anything else. Her catchphrase is "Afuu", which she utters every time she finishes yawning.

In the Xbox 360 game, Miki is in some way the main character besides Haruka, and her character has developed considerably over the game’s year-long time span. If special conditions are met in the game, she cuts her hair short and no longer dyes it blonde.

In The Idolmaster SP, Miki was unsatisfied with the way she was being managed, and switched to rival production company, 961 Production, as a member of the unit "Project Fairy".

As of The Idolmaster Dearly Stars, Miki has rejoined 765 Pro. She also received several changes in The Idolmaster 2, with her normal and "awakened" personalities having apparently been merged into one, and her hair now naturally blond and slightly wavier.

Hibiki Ganaha (我那覇 響, Ganaha Hibiki)

Voiced by: Manami Numakura^[6]

Million Live! archetype: Princess

Introduced in The Idolmaster SP as a member of "Project Fairy", Hibiki is an extremely energetic and cheerful girl hailing from Okinawa. Despite the rivalries with the other idols, she is very friendly, without becoming overly competitive like Takane. Hibiki has an outstanding number of pets, which she happens to lose quite frequently – her pets include a mouse, a hamster (named Hamuzō in the anime), a gerbil, a parrot, a rabbit, a cat, a dog (a female St. Bernard named Inumi in the anime), a pig, a flying squirrel and, oddly enough, a crocodile. She also has a pet chicken (named Kokemaro), who is apparently kept at her parents’ home in Okinawa.

As of The Idolmaster Dearly Stars, Hibiki has become part of 765 Pro. Her three sizes also shrank, since she is the only character that happens to, leading some fans to theorize that President Kuroi had lied about her measurements.

Takane Shijō (四条 貴音, Shijō Takane)

Voiced by: Yumi Hara

Million Live! archetype: Fairy

Introduced in The Idolmaster SP as a member of "Project Fairy", Takane is an elegant young lady from an affluent background, as seen in her outfits. While she has an elegant, spoiled brat personality due to her wealthy upbringing, she also has a refined, regal personality, and a princess-like nature to her. She hardly ever sees her mother, and her father often goes out on business trips – he is said to own a large company, much like Iori’s father, which is also why Takane has problems with her father – so she lives with her butler. Takane has an amazing passion for music, and is considered one of the smartest characters in the series, being fluent in numerous languages, including German. She also often observes far more detailed things than almost everybody else. A person of indeterminate origins, it is implied in the anime that she was not born in Japan. She is indeed mysterious in almost every way imaginable as she keeps most of her personal information hidden, especially where she came from. Despite being from a very wealthy family, Takane secretly takes an interest in commoner lifestyle and really enjoys ramen.

As of The Idolmaster Dearly Stars, Takane has signed up to 765 Pro.

Producer (プロデューサー, Purodyūsā)

Voiced by: Yūki Tai (drama CDs), Kenji Akabane (anime)

The protagonist of The Idolmaster. He is a young rookie producer who has been put in charge of a new set of pop idols. In the game, his name is never given, and is therefore decided by the player. His personality also depends on the player’s choices, ranging from sweet and protective to lewd and perverted. However, in the drama CDs, he’s most usually portrayed as somewhere in between.

In the anime, the producer remains unnamed, but is given the physical appearance of a young man with dark blue hair, glasses and a business suit. As the girls' producer, he is a very hard working person who tries his best to help the idols as their mentor figure, going to whatever lengths to make sure the girls are happy, healthy, and able to make their appearances. Like Yukiho, he too is afraid of dogs. While he mainly produces the rest of the girls, he sometimes co-produces Ryūgū Komachi with Ritsuko, often taking over when she is unavailable or it only involves a single member, even temporarily producing Ritsuko when she goes back on stage for a concert. He is most often Yukiho’s manager throughout the time.

The same Producer from the original anime also appears in the Million Live! anime adaptation, referred to as the Chief Producer (チーフプロデューサー, Chīfu Purodyūsā).

Producer (プロデューサー, Purodyūsā)

Voiced by: Genta Nakamura

The protagonist of the Million Live! anime adaptation. He is a rookie producer for 765 Production, assigned to manage 39 new 765 Production idols.

Jun'ichirō Takagi (高木 順一朗, Takagi Jun'ichirō)

Voiced by: Kan Tokumaru

The president of 765 Production, he takes the Producer under his wing and monitors his performance in charge of the girls. He is never seen as anything but a silhouette, and is rarely encountered outside of the 765 Pro office building, except at the final performance in The Idolmaster game. In The Idolmaster Break! manga, his appearance is revealed to be a middle-aged man around his fifties or sixties.

Before The Idolmaster 2 entered development, Jun'ichirō’s voice actor, Kan Tokumaru, passed away. As a result, in The Idolmaster 2, Jun'ichirō is given a backstory of why he did not return in the game – he has handed over the position of president of 765 Production to his cousin, Junjirō Takagi, so he can stop having to travel around Japan as he plans to move to Hawaii. Since then, Jun'ichirō is the chairman of 765 Production.

Junjirō Takagi (高木 順二朗, Takagi Junjirō)

Voiced by: Hōchū Ōtsuka

Jun'ichirō’s cousin and the president of 765 Production as of The Idolmaster 2. Much like his cousin, he appears only as a silhouette in the game. However, he does physically appear in the anime, although his face is still not fully shown. Owing to his background as a former producer, Junjirō has learned to know the idols that have been under his tutelage. As a result, he puts a lot of faith and trust in his idols, believing that they will eventually make it through. Because of this, he desires to promote them simply as they are and have them rely on their own talents and will to pull them through. Furthermore, he uses his resources well to keep his idols happy as he believes that they are at their best when they are happy.

Kotori Otonashi (音無 小鳥, Otonashi Kotori)

Voiced by: Juri Takita

An office clerk at 765 Production. Kotori originally only appears at the end of The Idolmaster arcade game, but then becomes a recurring character within the drama CDs. Originally featured on The Idolmaster arcade game webpage in the F.A.Q. section, she has accumulated enough fans to appear later on The Idolmaster media franchise. Among the few things disclosed about her personality and character, Kotori is known to be a little older than Azusa (making her somewhere in her early twenties), and despite not being an idol herself, she does love to sing. Her surname literally means "soundless", which refers to the fact that she was originally unvoiced. Kotori has a mole beauty mark on the right side of her chin that is often covered up by her microphone piece.

In The Idolmaster 2, Kotori remains a clerk at 765 Production. Kotori’s mole also appears as a DLC accessory.

In The Idolmaster anime, Kotori takes a more active role with the girls, especially when the Producer and Ritsuko are busy. A young girl, implied to be a younger Kotori (albeit with longer hair and a mole under her right eye; later confirmed to be Kotori’s mother, Kotomi), was revealed to have been produced by Junjirō and Kuroi before they went their separate ways.

Kotori is the protagonist of the manga Asayake wa Koganeiro, which depicts her in her high school days, during which she aims to become an idol.^[7]

She also likes to nibble at others.

Chihya (ちひゃー, Chihyā)

Chihaya’s Puchidol who loves to sing, but dislikes girls with large breasts, reflecting Chihaya’s self-consciousness with her own bust size, with Ritsuko being the only exception. She also develops a longer hair during winter that grows back soon after it is cut.

Takanya (たかにゃ, Takanya)

Takane’s Puchidol. Found in a Brazil-like tropical country, she loves ramen, has an unusual personality and talks by writing out words on paper.

Voiced by: Risa Taneda^[11]

This causes her to have very low confidence and easily get stressed by her routine. She is best friends with Megumi Tokoro and Elena Shimabara.

Kotoha was originally absent at the launch of Theater Days because her voice actress, Risa Taneda, took a hiatus from voice acting due to illness. She was eventually added to the game in February 2018.

Voiced by: Ayaka Suwa^[13]

Specialty type: Visual

Voiced by: Ibuki Kido^[12]

Specialty type: Vocal

Kana is a cheerful girl who loves to sing and aspires to be an idol. However, she is tone-deaf, and is thus a terrible singer.

Ai Hidaka (日高 愛, Hidaka Ai)

Voiced by: Haruka Tomatsu

Referred to by fans as the "younger clone" of Haruka, Ai is described as an unstoppable mini-tank who never loses heart despite her shortcomings and lack of experience. She is known to have a massive amount of energy, which unfortunately tends to work against her in auditions as her energy would end up overwhelming the judges. Her mother, Mai, was in fact one of the most well-known idols in Japan before she became pregnant with Ai when she was only 15 years old. As a result, 876 Pro took interest in promoting her as Mai's daughter, but Ai insists on becoming a popular idol on her own. This becomes a problem when Mai suddenly returns to the stage, causing Ai to feel that she has to contend with being compared to her own mother. She decides to face her head-on, using her mother's own song, "ALIVE", and defeat her with it. Afterwards, she continues on her own as an idol independent of her mother's celebrity status.

In the PlayStation 3 version of The Idolmaster 2, Ai appears as a DLC character in Catalog 3 as a S4U character. Once she is unlocked in S4U, players can have her perform with either of the songs "ALIVE" or "Go My Way".

A former hikikomori and internet celebrity known online as "Ellie", Eri was scouted to become an idol in real life.

Owing to her background revolving around the internet, she's also really prone to spouting out internet memes. As Eri begins to grow more as a live idol, she becomes more interested in how other idols are able to stand out. But when Eri encounters a series of strange incidents, the truth about her producer, Reiko Ozaki, comes out as she also reveals her troubled time as an idol, when she had to deal with the gossips revolving around her on the net. In response, Eri decides to trust in her producer as she adapts Ozaki's unfinished song "Precog" and continues her career as a live idol.

In the PlayStation 3 version of The Idolmaster 2, Eri appears as a DLC character in Catalog 5 as a S4U character. Once she is unlocked in S4U, players can have her perform with either of the songs "Precog" or "Shiny Smile".

Ryō Akizuki (秋月 涼, Akizuki Ryō)

Voiced by: Yūko Sanpei

Ritsuko's younger cousin who's very soft-spoken compared to her, Ryō is actually a boy who poses as a female idol, keeping that a secret from his co-workers at 876 Pro. Because of his feminine appearance, he was often mistaken for a girl, and so he wanted to become a male idol, but when he went to see Ritsuko about it, she took him to 876 Pro to become one. There, he ended up covering for a female idol, much to his chagrin. He did so well and, as a result, the studio hired him as a female idol. After a series of pranks done by rival idol Yumeko Sakurai, he successfully befriends her and becomes more motivated by her dreams, allowing him to refocus on becoming a popular male idol, the very dream he always had in the first place. Starting with Sōichi Takeda writing "Dazzling World" for him to compete with Chihaya, Ryō begins to pick up momentum to finally convince the staff to let him start his career over as a male idol. He finally gets to appear on Takeda's "Old Whistle" radio show. By the end of the story, he comes to be accepted by his fans and becomes more popular than ever as he continues on his dream. Later, he has to switch between glasses and contact lenses, depending on whether or not he is doing his idol work, so as to better distinguish between his male and female personas.

In the PlayStation 3 version of The Idolmaster 2, Ryō appears as a DLC character in Catalog 7 as a S4U character. Once he is unlocked in S4U, players can have him perform with either of the songs "Dazzling World" or "Kiramekirari".

Ryō later returns in The Idolmaster SideM, where he now performs as a proper male idol as he moves to 315 Production, as part of the F-LAGS idol unit. This makes him the only Dearly Stars main character to make another major appearance.

Minori Ishikawa (石川実, Ishikawa Minori)

Voiced by: Risa Hayamizu (Splash Red drama CD)

Ishikawa is the president of 876 Production. She is never seen as anything but a silhouette, but appears much more often than her 765 Pro counterpart, Jun'ichirō Takagi. She is said to be very good friends with both President Takagi and Yukio Igarashi. While she does believe in her idols like Takagi does, Ishikawa never hesitates to use anything she has in store for her idols to make them popular, like Mai's celebrity for Ai and Ryō's charm as a girl for him.

Manami Okamoto (岡本 まなみ, Okamoto Manami)

Manami acts as manager to both Ai and Ryō, though she focuses more on Ai due to her insecurity. Because of this, the two form a close bond. Manami has a gentle, hardworking, and kind personality, although she can be rather ditzy sometimes.

A talent agency introduced in The Idolmaster SP as the rival to 765 Production. As confirmed in the anime adaptation, 961 Pro is a much more established talent agency compared to 765 Pro.

Leon (伶音, Reon)

Voiced by: Minori Chihara^[6]

Introduced in The Idolmaster One For All, Leon is a powerful idol who trains all day and is always running off to auditions. Other than that, not very much is known about her.

In The Idolmaster Starlit Season, Leon forms a new unit with fellow 961 Pro idols Shika and Aya.

Shika (詩花, Shika)

Voiced by: Rie Takahashi^[6]

Introduced in The Idolmaster Stella Stage, Shika is an idol for 961 Pro with some kind of family relationship to the president of 961 Pro. Born and raised in Austria, she has come to Japan only recently. Because of this, Shika makes a liberal use of German phrases in her speech and is unfamiliar with Japanese culture and customs.

In The Idolmaster Starlit Season, Shika forms a new unit with fellow 961 Pro idols Leon and Aya.

Aya (亜夜, Aya)

Voiced by: Rina Hidaka

Takao Kuroi (黒井 崇男, Kuroi Takao)

Voiced by: Takehito Koyasu

The president of 961 Production, as well as Project Fairy and Jupiter's producer before their departure. Like most other producers, he's not seen, but as with the heads of other talent agencies, he appears as a silhouette, though the anime adaptation does give him a physical appearance, just not his face. After his original idols, Project Fairy, joined the rival 765 Pro in The Idolmaster 2, he formed a new idol group called Jupiter, composed of male idols. As of One For All, Jupiter had left 961 Pro, as confirmed in the anime adaptation. As a result, Kuroi hired a new idol named Leon.

Kuroi is a cruel and ruthless businessman who will do anything, legal or not, to promote his idols, but also take down 765 Pro, even going so far as to tell malicious lies about 765 Pro to idols under his tutelage. He tends to treat his idols as expendable pawns, using them solely for his personal gains. He is very picky too, choosing the most appealing and talented individuals available as his idols and employing underhanded business strategies to promote them, rather than allowing them to build their abilities naturally, the complete opposite of Junjirō's methods.

Kuroi and Junjirō Takagi were once old colleagues and friends, but they later had a falling out after Junjirō disagreed with how Kuroi raised his idols. Since that incident, Kuroi has vowed to destroy Junjirō, his company and his idols, all by any means necessary.

His company is in fact named after him, as "961" is pronounced ku-ro-i in Japanese.

The Idolmaster Cinderella Girls was released in late 2011.

Voiced by: Ayaka Ōhashi^[22]

A lively young girl who is scouted by the Producer for the Cinderella Project, she was originally taking personal lessons at a training agency to become an idol, but after being scouted for the Cinderella Project, she took lessons at the 346 Production facilities. She is similar to Haruka judging from her personality, although her voice and looks are quite different. She is almost always cheerful and optimistic, and is happy to have finally become an idol. Although sometimes overly emotional, she generally acts as the friendly-type "good girl". Scouted early on, she doesn't get to do any work at first, due to not enough girls being in the project at the time. Once two more girls are recruited, she is grouped into a unit called "New Generations" with Rin and Mio, after the three performed as backup dancers onstage for Mika.

Her Cinderella Master single, released on August 8, 2012, charted on the Oricon Singles Chart for eight weeks and topped at #12 on August 20.^[22]

Voiced by: Ayaka Fukuhara^[23]

A cool girl whose family runs a flower shop. She is similar to Chihaya in looks and demeanor.

Although cool and serious, she has a more feminine side that shows on occasion, usually when she is flustered or surprised by others. She is part of the unit "New Generations" with Uzuki and Mio.

Mio Honda (本田 未央, Honda Mio)

Voiced by: Sayuri Hara^[24]

Mio is an energetic girl who tends to get ahead of herself when it comes to wanting to become a popular idol. She is the de facto leader of "New Generations" and seems somewhat similar to the Futami twins, Ami and Mami, both in her expression and playful attitude. She even has a habit of referring to people around her with nicknames, much like the Futami twins. Although she had auditioned for the Cinderella Project before, she came up short. She eventually managed to get through on her second try. She tends to be very good with singing and dancing, though she can get tired quite easily during lessons. During the first mini-concert for "New Generations" to promote their Debut CD, she became disappointed with the small crowd that turned up and almost quit being an idol altogether because of it. After some time, the Producer and fellow idols convinced Mio to stay as an idol, and she has since been less focused on the size of crowds at concerts, instead focusing on the excitement of the crowd.

Chieri Ogata (緒方 智絵里, Ogata Chieri)

Voiced by: Naomi Ōzora^[26]

Chieri is a very shy girl with a demeanor and voice similar to Yukiho. She has a kind of stage fright, as she is incredibly nervous whenever on stage, although she seems to be able to control herself somewhat when she thinks of the audience as frogs. It seems she is even more nervous when her fellow idols are on stage too instead of her, as she was very anxious during the performance where "New Generations" was doing the backup dancing at Rika's concert. She carries a four-leaf clover around with her, although it's unknown if she keeps it for luck, or just happens to like clovers. She is in the unit "Candy Island" along with Anzu and Kanako.

Miku Maekawa (前川 みく, Maekawa Miku)

Voiced by: Natsumi Takamori^[27]

Miku is a girl aiming to be a cute pop idol. She seems similar in demeanor to Iori, especially with her different attitudes on stage and off. She almost always wears cat ears and punctuates her sentences with the kitty sound "nya" (Japanese onomatopoeia for "meow"). She has an inexplicable affinity for cats, although she doesn't have one as a pet, and even hates fish. Although she really wants to act cute, she can get mad when she feels she isn't getting enough attention. She appears to have a large collection of different cat ears, but tends to always wear the same pair at work. According to her, she works hard like a cat, and is always ready for work. She carries cat ears everywhere she goes so she can be ready for work at any time. She often has a totally different attitude when not on camera or onstage. However, as soon as she knows the fans are watching, she puts on the cat ears and acts like a cute and innocent idol. She is one half of the unit "Asterisk" along with Riina.

Her Cinderella Master single, released on August 8, 2012, charted on the Oricon Singles Chart for eight weeks and topped at #11 on August 20.^[27]

Anzu Futaba (双葉 杏, Futaba Anzu)

Voiced by: Hiromi Igarashi^[28]

Anzu is a young reclusive girl who's so lazy she detests the idea of work itself. She tends to be similar to Miki, although much smaller in figure despite being older, with her lazy personality and tendency to fall asleep. She is usually seen sleeping at any possible time, especially during the early parts of the anime series. Her laziness is also highlighted when she and her fellow idols held a strike in protest of New Generations' debut, where Anzu demanded "8 days off every week". Although very lazy, she learns to work normally later on. She also seems to be a bit of a genius, as showcased when she was on a quiz show with her unit against a rival idol group, easily answering obscure questions and solving a complicated math problem incredibly fast in her head with almost no effort. Later on, she seems to have mostly done away with her laziness, but is still seen being somewhat lackadaisical about hard work. She is in the unit "Candy Island" along with Chieri and Kanako.

Her Cinderella Master single, released on April 18, 2012, charted on the Oricon Singles Chart for ten weeks and topped at #4 on April 30.^[28]

Riina Tada (多田 李衣菜, Tada Riina)

Voiced by: Ruriko Aoki^[29]

Riina is a girl who loves rock music and aspires to be a rock idol. She is somewhat similar in demeanor to Makoto. Although almost the opposite of Miku, she and Miku were paired up as a unit, mainly because they were the only idols who hadn't debuted at the time. After some seriously heated arguments and fights, they learned to get along and perform together, although they still tended to be at odds with each other often. Riina plays guitar, but apparently only knows some simple chords and has headphones on most of the time, listening to rock music. Like Miku, who has a large collection of cat ears, she has a large collection of headphones, but is always seen with the same pair at work. She has a great admiration for a young boy who tries out her guitar and plays an amazing sequence of riffs on it, despite him being left-handed and her guitar being a right-handed one. She also has a tendency to say that something is "rocking", usually when she likes something, like her unit's name, which was originally just a placeholder placed by the Producer, since the unit didn't have a name on the sign-up sheet for the idol festival. She is one half of the unit "Asterisk" along with Miku.

Voiced by: Aya Suzaki^[30]

Minami is a college student who plays lacrosse. She is similar to Ritsuko, being hardworking and responsible. She doesn't have a lot of character development, despite the fact that during the idol's training camp, she was elected as the Cinderella Project's supervisor due to being the oldest idol. However, she ended up overworking herself and fell sick during the idol fest, so she was initially unable to perform onstage. Later on, she managed to get over her sickness in time to perform with the rest of the idols during the finale. She is one half of the unit "Love Laika" along with Anastasia.

Ranko Kanzaki (神崎 蘭子, Kanzaki Ranko)

Voiced by: Maaya Uchida^[31]

Ranko is a girl who dresses in goth-loli style and speaks with strange phrases like role-play. Disregarding her strange speech, she is very similar in looks and demeanor to Takane. Her unusual style of speech makes it hard for the Producer to understand her, so much so that he writes down her phrases in a notebook along with their "translation." She is the only idol in the Cinderella Project to have debuted by herself rather than being part of any unit. Although she dresses in a goth-loli style and talks like she is from "the abyss" (according to her), she actually hates scary movies and stories, and is very easily frightened by such things. Initially, the Producer had decided to promote her debut and song with a straight-up horror theme, but he was told that she didn't like horrific things, so he changed it to a Gothic theme. During the idol fest, since Minami was unable to perform with Anastasia, she went on with her and performed with her surprisingly well, despite never having practiced it (although she returned to solo work afterwards). Her stage name is "Rosenburg Engel".

Anastasia (アナスタシア, Anasutashia)

Voiced by: Sumire Uesaka^[32]

Nicknamed "Anya", she is a half-Russian girl. She seems quite similar to Takane, such as her native country not being Japan and her notice of certain small details that other tend to miss. Since she is Russian, she often speaks in Russian accidentally (which is subbed as gibberish), before remembering to switch back to Japanese, though she is not as fluent in Japanese. However, she has no problem in listening to any conversation in Japanese, seemingly able to understand it. She often asks Minami how to say certain things in Japanese or whether she said something correctly or not. She is very talented in singing initially, which lead to her being paired with Minami, who is apparently very hardworking. She is one half of the unit "Love Laika" along with Minami.

Her Cinderella Master single, released on November 13, 2013, charted on the Oricon Singles Chart for six weeks and topped at #13 on November 25.^[32]

Miria Akagi (赤城 みりあ, Akagi Miria)

Voiced by: Tomoyo Kurosawa^[33]

Miria is an innocent 11-year-old girl. She seems somewhat similar to Hibiki, being primarily energetic and cheerful. She is the youngest idol in the Cinderella Project and tends to hug and cling to older girls, especially Kirari. Although incredibly innocent, she can be a bit troublesome at times, hardly ever bothering to stop the other girls from harassing or pranking the Producer, and she even once helped Anzu flee from the other idols' sights so she could sleep all day. She is part of the unit "Dekoration" along with Kirari and Rika.

In the spin-off manga U149, she is not yet a member of Cinderella Project, but rather of the Third Entertainment Division in a not yet named talent agency. She is also one of the nine idols appearing in the anime adaptation of that same manga, making her the only main character in the original Cinderella Girls anime adaptation to appear as a main character in another anime adaptation of the subseries.

Rika Jōgasaki (城ヶ崎 莉嘉, Jōgasaki Rika)

Voiced by: Nozomi Yamamoto^[34]

Rika is the 12-year-old younger sister of fellow 346 Production idol, Mika Jōgasaki. She seems similar to Ai with her attitude on becoming well-known. Her sister wanted her to join her as part of the idol company so they could perform together in the future, but she stayed with the Cinderella Project to become a star without flaunting her sister's already-established popularity. Whenever she runs into her sister, she will exclaim "Onee-chan!" and hug her or cling to her obsessively. She is part of the unit "Dekoration" along with Kirari and Miria.

Kirari Moroboshi (諸星 きらり, Moroboshi Kirari)

Voiced by: Rei Matsuzaki^[35]

Kirari is a tall 17-year-old girl. She clings to Anzu and keeps her in check like an older sister, but gets put into a different unit than her. She is somewhat similar to Yayoi, although much larger in figure and three years older, with her hyperactive personality. Similar to Azusa, she doesn't mind the small things and being an "older sister" type, and tends to be laid-back with her approach to work and events. Although the leader of her group, her partners tend to be able to do whatever they want, because she doesn't always effectively take charge or keep them in check like she does with Anzu. She is part of the unit "Dekoration" along with Rika and Miria.

He compares other people to flowers when talking about them. He is also skilled at sewing and cooking. Since he is often seen doting on Pierre so much, he is considered the leader of his own unit. As an aficionado of idols, Minori understands what other fans want and, because of this, he habitually takes pictures with Kyōji and Pierre on his smartphone and emphasizes the importance of his unit's costumes. Before performing, he looks at flower stands sent to the agency by fans and praises his fellow teammates whenever they do a successful job; he is also protective of them.

Her image song "ALIVE" was extremely popular, and she even later allowed her daughter to adopt the song as her own when she became an idol.

Voiced by: Yurin (Innocent Blue drama CD)

When Eri was still a net idol, Ayane was supportive of Eri, wishing the best of her ability whenever she could.

In The Idolmaster 2, Cineria is the name of a news reporter. This seems to allude to the ending of The Idolmaster Innocent Blue volume 3. A unit with this name also appears on the "DO-TOP TV" ranking.

Reiko Ozaki (尾崎 玲子, Ozaki Reiko)

Voiced by: Yū Asakawa (Innocent Blue drama CD)

Ozaki temporarily makes a contract with 876 Production and debuts Eri under the company label. Ozaki herself was once an idol, part of an idol duo known as riola, paired with another girl, Satomi Kondō. During her idol career, Ozaki never got past F-Rank due to slanderous comments about the unit and their agency's president that were posted online. This caused her to hate the internet and drives her desire to protect Eri from it. The song "Precog" was going to be her last image song, but it went unfinished by the end of her career. She later allowed Eri to finish the song and use it as her own.

Sōichi Takeda (武田 蒼一, Takeda Sōichi)

Voiced by: Tatsuhisa Suzuki (Neue Green drama CD)

Takeda has a strong passion for instrumental jazz and classical music and is in fact the host of a radio show called "Old Whistle", which he created to honor classical music. However, he also has a dream of creating an idol that could help ascend music. In fact, before he took interest in Ryō, Takeda only allowed one other idol, Chihaya Kisaragi, whose talents he was quick to recognize, to appear on "Old Whistle". Chihaya had personally approached Takeda several times to have him write a song for her, only to be turned down as he felt that talent like hers would be wasted on a song written on a whim. Takeda was also the one who wrote the song "Dazzling World", which eventually became Ryō's image song. As he collaborates with Ryō, Takeda is able to learn and challenge himself to the point where Ryō can finally stand and the two can achieve their respective dreams.

Introduced as rival to Ryō Akizuki, she is thought to be an extremely talented idol, though it is revealed that she has cheated her way to the top by sabotaging rival idols by various means, including giving them a candy that clogs the vocal chords or making the stage floor slippery. After Ryō convinces her to stop, Yumeko reveals that her dream was to appear as a guest on Takeda's radio show "Old Whistle". Despite being rivals, she frequently hangs out with Ryō to talk about their upcoming auditions. After Ryō reveals himself as a boy, Yumeko starts to have a crush on him, much to her discomfort.
