is a character CD series[1] that started as a collaboration between Vocaloid producers and popular voice actors but expanded into a media franchise with its own animation, multiple stage plays, manga anthologies, video games, and merchandise.

The characters of Tsukiuta are split into four idol groups under the fictional Tsukino Talent Production.

[1] Voiced by: Yūki Kaji / Composition by Satsuki ga Tenkomori Month - December Birthday - December 12[4] Stage Cast: Kakeru is a fair-skinned young male with neck-length blond hair and orange eyes.

[8] A cheerful labor (part-time job) boy, Kakeru is lively, works with all his might with little complaint, is rarely discouraged, and does not like to lose.

[9][10] Kakeru carries a strong sense of pride and believes in self-reliance, as shown by how he chose to work part-time to support himself instead of relying on his parents' allowance since it was his choice to move out of his home.

Voiced by: Kōsuke Toriumi / Composition by Machigerita, Misato Murai (childhood) Month - January Birthday - January 8[13] Stage Cast: Hajime is a tall, fair-skinned, well-built young male with neck-length black hair and purple eyes.

[15] Despite his repertoire of skills and intellect, as well as his family background, Hajime keeps himself grounded and does not let himself get carried away with what he has accomplished.

[19] He and Haru first spoke with each other sometime after they'd been assigned to the same class in their second year as junior high school students.

Voiced by: Toshiki Masuda / Composition by Nijihara Peperon Month - February Birthday - February 14[20] Stage Cast: Koi is a fair-skinned young male with short bubblegum-pink hair and slightly darker pink eyes.

While initially one of the shortest among the male idols, he has experienced the most height growth in the past few years.

He is good at socializing, making him a person with lots of friends of either gender, and he always encourages those who feel down.

He's also quite the mood-maker, plays the funny man role, and can throw sharp retorts, making him a reliable member of his unit.

Voiced by: Tomoaki Maeno / Composition by Yuuyu Month - March Birthday - March 19[22] Stage Cast: Haru has collar-length, light sandy green hair, slightly parted bangs, and a natural ahoge.

Haru is described as a calm and gentle young man and is someone everyone relies on—practically a mother-type figure with a big heart on the level of a "holy mother" or the Virgin Mary.

He is also very intelligent and has earned himself the titles of "trivia king" and "Harupedia," although he has only beaten Hajime twice in academics.

[26] Arata is a laid-back, unhurried person who takes things at his own pace, often compared to a cat in a sunny area.

He tends to be someone who sits at either end of the spectrum when it comes to working; he can be quite difficult to handle once he loses his enthusiasm, but he displays an overwhelming ability to concentrate and talent when it comes to interests and goes all the way when having fun.

[27] Voiced by: Kenn / Composition by Nem Month - May Birthday - May 5[28] Stage Cast: Jonin Tatsuki[6] Aoi has fine, soft hair that is platinum-blonde with a faint tawny shade,[29] with two distinctive tufts of hair bent outward on the top of his head, reminiscent of wings, and sky-blue eyes.

[28] He is a naturally diligent, serious person, which makes it hard for him to laze around and take things easy.

He was scouted together with his childhood friend, Arata, when they tried to return Kuroda based on the contact address on his collar.

[30] Voiced by: Masahiro Yamanaka Kanade has light grayish-brown hair and brown eyes.

Thanks to Hajime's careful guidance and leadership, the members of Six Gravity do not cause much trouble for Kanade, making his job as their manager rather easy.

[39][40] Voiced by: Yasuhiro Mamiya Dai is a well-built man with dark hair and brown eyes.

[53] On April 3, 2022, it was announced that the series would be receiving an anime film titled Rabbits Kingdom the Movie.

The ending themes are sung by each character in the order of their representative months, starting with December.

Suteeji Dai-ni-maku ~Tsukiuta Kitan "Yumemigusa"~) is the second installment of the stage play series Tsukiuta.

Two versions of the show were performed once per day: the Sakura Chapter (桜の章, sakura-no-shou), with more focus on Six Gravity members Arata and Aoi, and the Moon Chapter (月の章, tsuki-no-shou), centralizing Procellarum's You and Yoru.

Suteeji Dai-4-maku "Lunatic Party") is the upcoming 4th installment of the Tsukiuta stage play series.
