The general premise of this anime is about these crystalline organisms called gems which inhabits the world. These organisms are actually immortal sparkling valuable jewels living on an island and are always fighting the Lunarians, another species that inhabits the world in which their only purpose is to attack the gems, break them and take them to ‘the moon’ for decoration. This series is basically about the gems fighting and surviving the attacks from the Lunarians for millennials.
It’s been a long time since I actually intended to watch this series. The main reason I want to watch this is obviously because of the gorgeous 3D animation which is pretty much non-existent anywhere else, at least in the anime industry. The scene that pretty much sold me to the anime is the scene where Diamond is running at night under the moonlight. It’s just so beautiful!
