THE iDOLM@STER Character resumé

To all staff and members reading this resumé: To be a successful idol, what do you think it takes? Looks? Your skill in singing? Yes, those traits are indeed very important to be an idol, but I believe Knowledge is important as well. Yes, Knowledge. Working together, I'd like to see what kind of Knowledge you have.


Producer and part-time Idol!
"Ahhh, what am I doing here... w-well, I can't do anything about it now... Alright! When I'm on stage, you're my producer, so support me well. ... Umm, I really mean that. OK?"

THE iDOLM@STER Starlit Season Profile

"My name is Ritsuko Akizuki. Project LUMINOUS, looks like it was a stimulating experience for me. Whatever the activities are they, I'll always looking for the skills. Please take care of me, Producer-dono♪"


"I'm Ritsuko Akizuki. If we're going to do this right, then I'm going to aim for the top as planned."


Cool and smart, Ritsuko Akizuki worked at the 765 Production office as an intern after having graduating from high school, but after hearing that the agency is low on budget and has too few idols, she decided to debut herself.

Loving to work and managing things, she is the perfect type of business woman. Always keeping herself busy, even on her days off she finds something to do at the 765 offices, such as paperwork. On rare occasions, she will even act as a producer herself. Not really looking anything like idol material, and even admitting this herself, she still works very hard as an idol. Her future dream is to become a manager of a business corporation one day.

Ritsuko also has a serious side to her, and if she feels that anyone is slowing her down in her work, she will scold them or brush them aside, occasionally correcting even the producer if he isn't doing his job right.

Ritsuko's family consists of herself, her mother, and her father. Her parents share the same trait as Ritsuko: being business-like and hardworking. They own a shop in the city.

Physical description

Ritsuko has shoulder-length brown hair, which she always keeps in one of these hair styles depending on the appearance: one or two braids, or a spiky high-bun.

In THE iDOLM@STER and THE iDOLM@STER Dearly Stars, she wears a white shirt with blue stripes and a dark green skirt with a light brown belt. In SP, the outfit is a plaid dark green jumper with a blue shirt under it and black trousers. At the bottom is a pair of blue shoes. This serves as her variant of the costume Nexus Casual in THE iDOLM@STER Live for You!.

In THE iDOLM@STER Stella Stage and THE iDOLM@STER Starlit Season, her casual outfit consists of a white dress-shirt with a yellow-orange cardigan layered on top of it, both of which have short sleeves. The front of the cardigan has a pattern that features creme, beige, and green-colored rhombus shapes. She also wears a red skirt with a brown belt around it, as well as a pair of green socks, and brown shoes.

Game Appearances

THE iDOLM@STER (Xbox 360)


THE iDOLM@STER Dearly Stars

In THE iDOLM@STER Dearly Stars, Ritsuko is Ryo Akizuki's cousin, and the one who helps him enter the idols' world. She also introduces Ryo to Makoto Kikuchi, who would become help him reach his goals. She can also train the 876 PRO idols the choreography panels for "Mahou o Kakete!".


Before the events of THE iDOLM@STER 2, Ritsuko was an idol and the personnel shortage in the agency forced her to be a clerk as well. She quit being an idol because she was aiming to be a producer in the first place, and saw her job as an idol as a stepping stone. At this point, she became the official producer of the 765 Production unit, Ryuuguu Komachi. While having this job, she denies ever wanting to be an idol and constantly says that she wasn't suited for the job. However, she often slips up and admits that she misses being an idol, particularly when she goes onstage with other idols or dances when egged on.[1]

In the PlayStation 3 release, Ritsuko has a playable route where the Producer helps her manage Ryuuguu Komachi and makes a stage appearance with the help of Mami Futami. Ritsuko now wears her hair in a spiky high-bun and her outfit is a business suit with a green shirt, more fitting with her new position as a Producer.


Ritsuko is one of the four main idols in the Honey Sound version of THE iDOLM@STER SHINY FESTA, along with Haruka, Azusa, and Chihaya.

Other Media Appearances


In Melody of Serenity, Ritsuko appears as a member of the unit Proro along with Yukiho and Haruka. She becomes a line of communication for feelings with Chihaya's producer and defuses their initial dislike for each other. Ritsuko and Haruka also team up together to stop Yukiho's antics of digging holes and even manage to take her shovel from her. The trio constantly supports Chihaya through out the novel and help her make a successful idol debut.

Ritsuko then stars in Heart-throbbing Summer Days, as the novel explains how she became part of the unit Proro. After failing to become a manager, she joins 765 Prodution as an intern. She tries to produce Haruka, but winds up being forced into becoming an idol herself. Ritsuko, Haruka and Yukiho are then made to train several days at a boardinghouse as rivals. They each learn a debut song and learn about the harshness of dance lessons and cooking. When the girls finally debut, they realize their debut songs all are simply different harmonies of the same song. The girls debut as Proro and are amazed that all three of them became great idols.

THE iDOLM@STER Live for You! OVA

Ritsuko appears along with the other 765 Production idols leaving the office after preparing for a fan appreciation event. She is later seen in the dressing room of the event informing Haruka, Chihaya and Miki (who were lost on the other side of Japan) about the Producer searching for them. She explains the girls can make it to the concert if they make it to the bullet train station. After Iori picks the trio up in a helicopter, Ritsuko is seen with the other 765 idols as they go to the event.

THE iDOLM@STER relations

Ritsuko becomes D-Love's producer after Miki's producer disbanded the unit Namco Angel. She also steps in as Melt 'Chu Up!'s manager. The unit Devil Angel cheats their way into forcing both of Ritsuko's units to lose to Tougouji Production. Because of trouble promoting her units caused by the agency, the Producer decides to disband all of the 765 units and put all of the idols into an ALLSTARS unit. Ritsuko is shown performing relations alongside the other 765 Production idols and with THE iDOLM@STER GRAND PRIX.


Ritsuko is not seen in the manga until the third volume when she moves into the 765 dorm, as well as Makoto, Ami, Mami and Azusa. She joins 765 Production and helps both manage and promote the idols of the agency while becoming one herself. She literally solves most the problems in the agency single-handedly and ends 961 Production's take over of Miki Hoshii. She is seen proving to be a good dancer, great at quiz show appearances, and even explaining business to her "producer", Yuutarou.

The mangaka himself wrote that Ritsuko was not in the first volumes simply because she would have easily solved all of the problems that Yuutarou Takagi was faced with.


Ritsuko appears in Puchimasu! along with the other 12 idols. Her Puchidol is Chicchan.

THE iDOLM@STER Dearly Stars manga


At the start of the anime, she has already quit being an idol and appears as an idol producer. In episode 6, there is a description of Ritsuko personally choosing the unit Ryuuguu Komachi to be formed, and it can also be confirmed that she has a car license. (However, there is even a description of her driving a medium-sized car, which according to the Road Traffic Law, only people over 20 years old are allowed to drive.)

She has many conversations with the members of Ryuuguu Komachi, and there are many scenes where she teaches Miki how to be polite.

She still has a desire to work as an idol, but she thinks that working both as a producer and an idol is half-baked, and she had no intention of going on stage. However, in episode 18, Azusa Miura was absent due to the mumps, so she appeared in the secret live in her place, much to the delight of her fans at the time.

In episode 25, she was introduced by Azusa as a "producer and idol" without any warning, and she was forced to appear as a surprise at the live, and half reluctantly stood on stage with the 765 Production idols.

Trivia and Fan Culture


Ritsuko with her hair down.
  • In the games, Ritsuko never takes her glasses off or lets her hair down, regardless of the costume or event. The only occasion she lets her hair down is when using the pajama costume in Live For You!. A "glasses" accessory will remove her original glasses in THE iDOLM@STER SP, but in THE iDOLM@STER 2 and ONE FOR ALL, the accessory will go on her head instead of her face, leaving her original glasses intact.
  • Ritsuko sometimes uses the "-Dono" (Japanese: 殿 Dono) honorific when referring to the producer, calling them "Producer-dono" (Japanese: プロデューサー殿) instead of simply "Producer". While normally used to indicate that the person referred to has the same (high) rank as the referrer, it commands respect from the speaker.
    • The honorific roughly means "lord," "master" or "milord."
  • Ritsuko is known by her schoolmates to have outstanding leadership skills. In fact in THE iDOLM@STER Drama CD Scene.05 EXTRA STAGE 1, she was appointed to be a lieutenant of a police force for a day.
  • Ritsuko has some skills in Mixed Martial Arts, which is noted in THE iDOLM@STER Drama CD Scene.01 ~Yukiho Hagiwara & Makoto Kikuchi Compilation~ when a couple of gang members try to kidnap Yukiho Hagiwara until Ritsuko comes in and beats them up.
  • Ritsuko has a running gag in many iDOLM@STER mangas. She will appear with her hair down for various reasons, but no one in the cast will be able to recognize her. It usually ends with her getting frustrated that people like her better without braids or glasses.
Ritsuko promoting for LAWSON.
  • Ritsuko has had the most hairstyle changes than any other character in the series.

Fan Culture

  • When Naomi Wakabayashi performs Ippai Ippai at iDOLM@STER events, it is common for fans to chant the lyrics of the chorus accordingly.
  • While it wasn't intended, Ritsuko's casual wear looks extremely similar to that of LAWSON employees' uniforms. This lead to Namco Bandai using her as the representative for all THE iDOLM@STER related LAWSON merchandise. Ritsuko was also honored by becoming an official honorary store manager.
