About

Tens of thousands of years in the future, in a world where the moon has split into six and humanity has perished, the Gems awaken. Gems (Beings that inhabit the Earth in place of humans. They speak Japanese, but have no knowledge of things from the past like 'humans' or 'Earth'. They do not know what happened in the past.) Lunarians (Beings that live on the moon and come to Earth to abduct Gems. They do not speak on Earth. They are the closest existence to humans and even consume food. They are led by a figure known as Aechmea.)
