Ai is the daughter of a former superstar idol in Japan, Mai Hidaka. She is very peppy and motivated by the fame of her mother, although she cries at defeat. She is a hot blooded girl, known for having a lot of energy and her determination. Ai is prone to shouting most of her speech, especially when excited. She is also good at all kinds of television shows.

Game Discography

THE iDOLM@STER Dearly Stars

Ai, wishing to become an idol as famous as her mother once was, has been participating in tests at various talent agencies, but she has failed every single one of them. Her inability to even begin to follow into her mother's footsteps becomes a complex to her. As Ai bursts into tears, alone in a public park, she is approached by 765 Production idol Haruka Amami, who was a special judge at one of the tests Ai has taken. Having sensed something special about Ai's singing, Haruka comforts her and introduces her to 876 Production's president Ishikawa. The president is very quick to invite Ai into 876, as she believes that her mother's name alone should be enough to propel Ai to the top. Ai protests against it, stating that she wants to become an idol using only her own strength. She is then given one chance to prove herself, at a rookie idol audition.

Along with fellow idol Ryo Akizuki, Manami Okamoto was assigned as Ai's manager, with Eri Mizutani already having Reiko Ozaki as her producer. However, Manami was later dismissed, leaving Ai to manage herself alone.

Ai continues to rise up in ranks to become a top idol, however she will have to be independent and have to fight off the shadows of her past, including Manami, Haruka and her own mother Mai Hidaka.


Ai makes her HD debut in THE iDOLM@STER 2 on the PS3. She is downloadable from the 3rd DLC Catalog as an in-story rival and Stage For You! performer and sings "ALIVE" and "GO MY WAY!!". Her appearance has not changed in design since this update.

THE iDOLM@STER: Gravure For You!

Ai also appeared in Volume 7 of THE iDOLM@STER: Gravure For You! as a guest idol, wearing the "Exercise Wear NEO" costume. She sings the BGM music "ALIVE", "GO MY WAY!!", and "HELLO!!" in this mode. She uses the same model as her iDOLM@STER 2 appearance. She has an introduction video featured in volume 7.


Ai Hidaka appears as a rival in the STAR OF FESTA mode for Honey Sound, Groovy Tune, and Funky Note. She is an A rank rival who can give her Name Card to the player while in the HARD difficulty. Obtaining her Name Card adds 40 points to the player's score after their performance.

Initially, Ai is the Rank Up Festival boss for the D3 rank, where she displays her skill, とつげき豆タンク! (Tankette Assault!), which causes the player's Normal and Memory appeal to be worth 10 point max while she bursts. She is only available to be seen while she burst appeals, which displays her performing the song ALIVE in her 876PRO CUTE AI costume. Unfortunately, she is unable to be outside of the short time from the burst appeal.

However, she later debuted in the unit Dearly Stars alongside her fellow 876 Production idols: Eri Mizutani and Ryo Akizuki. Reprising a performance similar to her iDOLM@STER 2 appearance, her unit displays the song "HELLO!!".


Ai Hidaka and Eri Mizutani make a cameo appearance in one of Ryo Akizuki's SR+ cards.
