IDOLM@STER: Xenoglossia Collection 1 contains episodes 1-13. 107 years ago, the Moon was destroyed in a massive cataclysm that shattered Earth's former satellite into 81 quintillion tons of orbital debris. However, thanks to super-science, the Earth itself was saved and today no one really thinks much about that century-past disaster. Which is why when teenage Haruka Amami auditions for something called the Idolmaster Project, she thinks she's trying out to be a singing idol. Instead, Haruka finds herself at a secret school run by the Mondenkind Agency, living with a group of other girls who have also been selected as candidates to pilot an IDOL - an advanced robot specifically designed to intercept falling chunks of moon rock. Unfortunately, there aren't enough Idols for all the potential pilots, and there are some who will do anything to earn the coveted seats, even if the consequences are lethal. And then there's the question of whether the Idols are really just robots, because from almost the first moment, Haruka starts to feel emotions resonating from within the Idol called Imber. The mysteries are mounting, the competition is furious and the mission to save Earth is on! IDOLM@STER: Xenoglossia Collection 2 contains episodes 14-26. Things are getting a lot more complex at Modenkind and some of the things that Haruka is learning about the IDOLs are more than a little worrying. For example, while the mechs aren't free to do what they want, they're not exactly obedient machines either; and the relationship the IDOLs form with their pilots is much more complicated than master and servant. Haruka is beginning to realize that her own feelings toward Imber aren't exactly what she'd expected them to evolve into. But there's no time to analyze what's going on inside her heart, because suddenly all of Modenkind is under siege, hit from both within and without as hidden spies combine with outside attacks and ruthless kidnappings. Who is trying to destroy Modenkind and why? And how is it connected with the real secrets behind the IDOLS?
