THE iDOLM@STER CINDERELLA GIRLS U149) is a Japanese spin-off manga series of the The Idolmaster Cinderella Girls free-to-play simulation video game by Cygames and Bandai Namco Studios. The series is created by Kyowno, focusing on girls under 149 centimeters tall to be idols.
Announced during DAY 2 of "THE IDOLM@STER CINDERELLA GIRLS 10th ANNIVERSARY M@GICAL WONDERLAND!!!" final tour concert, a TV anime adaptation of the spin-off manga THE iDOLM@STER Cinderella Girls: U149.
Chie, Kaoru, and Risa received their solos through the manga. Takumi and Rina share this distinction in WIND WIND GIRL.
In the U149 canon, Momoka and Kaoru did not address the Producer by their special honorifics ("Producer-chama" for Momoka, "Sensei" for Kaoru); instead they call him by "Producer-san" or just "Producer".
Despite the division consisting of 12-and-under idols, Rika Jougasaki and Mary Cochran are not in the division due to their height exceeding 149cm. They are, however, involved with several story arcs later.
