Idolmaster: Xenoglossia (Japanese: アイドルマスター XENOGLOSSIA Aidorumasutaa XENOGLOSSIA) is a spin-off anime television series by Sunrise, loosely based on Bandai Namco's game series THE iDOLM@STER. It was first broadcast in Japan on April 2, 2007 on TV Hokkaido and various other UHF television stations, three months after the release of THE iDOLM@STER (Xbox 360). The series was also broadcast over the internet on the Japanese website @nifty. The series has been licensed by Sentai Filmworks in North America and was released on DVD in late 2012 with English subtitles.[1] Starting from March 2018, Xenoglossia has been available for streaming on Hulu JP.


107 years before the beginning of Xenoglossia, the Moon was destroyed in an event known as "Lost Artemis." Remnants of the Moon formed quintillions of debris that floats through Earth's orbit. After over a century, humanity is able to live mostly normally.

Haruka Amami wants to become an idol, and decides to take part in the "Idolmaster Project." She believes this is an audition to become an idol, and is excited to be accepted and goes to Tokyo to start work at the Mondenkind Agency. She is surprised to find that this was not an idol audition, but instead a secret audition to find "Idolmasters," the girls who pilot robots known as iDOLs to destroy the debris threatening Earth.

Haruka is hesitant to become an Idolmaster, but after being rescued by the iDOL known as Imber, she decides to join Mondenkind, working alongside the other girls to protect Earth and find the remaining iDOLs.

A rival to Mondenkind, Turiavita, seek to take the remaining iDOLs from Mondenkind, as well as find the missing iDOLs so that they can destroy humanity. Much of the series focuses on the battle between Mondenkind and Turiavita for control of the iDOLs as well as the shifting bonds and rivalries between the Idolmasters themselves.

  • Since Idolmaster: Xenoglossia was initially made without Namco's supervision, it features an entirely new line-up of voice actresses.
  • Earlier upon the broadcast, the anime was not well-received, due to its different nature compared to the games. It is also said that the anime, along with various other reasons, caused such an unrest within the fandom, which peaked on Tokyo Game Show 2010.
  • The voice actresses were also not involved further in the franchise, most likely as a result of the negative reception from the fandom.
    • However, this all has since changed, with several fans nowadays starting to appreciate it as well as some of the voice actresses participating in BANDAI NAMCO Entertainment Festival in 2019.
  • Xenoglossia also marks iDOLM@STER's first involvement with the label Lantis.
  • Penguins are heavily featured in the anime. Yayoi likes to wear a giant penguin costume during times.
  • Idolmaster: Xenoglossia was featured in Super Robot Taisen: X-Omega for a limited time Christmas themed event where Haruka and the Imber could be obtained as exclusive event units.
    • The Producers of the game wanted to introduce mecha series that were unconventional and not suited for mainline Super Robot Taisen games due to logistical or licensing reasons, and Xenoglossia was easily a top choice for adoption.
