A Land of the Lustrous parody. Your race... human or gem, it's up to you.
About
White bodies, round heads. But their bodies are made of gemstones. 【The Origin of This World】 This planet was visited by meteors six times, chipping away at it until six moons were born. As the world withered and the land was reduced to a single shore, all living things fled to the sea. On the barren shore, organisms adapted to the sterile environment appeared. Back when there was only one moon, among the prosperous life forms, those who were too slow to escape sank into the ocean. They were consumed by microscopic organisms living on the seabed and reborn as inorganic matter. Over vast stretches of time, they arranged themselves into regular patterns, became crystals, and were washed up on the shore once again. That is what we are. This is the story of an endless battle between the Gems, who possess immortal bodies that can be reconstructed even if shattered into pieces, and the Lunarians, who attack from the moon to turn them into decorations. 【The Gems】 Round heads and white bodies. Their skin appears white, but their insides are gemstones. Microscopic organisms are trapped within them as inclusions, serving as their life force. Therefore, even if they are smashed to bits, turned to powder, or sink into the sea, they can be brought back to life as long as their fragments are reconnected; shattering is merely a state of suspended animation. This is a trait unique to them. They do not bleed, and they feel no pain. Each has a weapon and a specific role. They primarily perform patrols and combat in pairs. They wear uniforms. Gems with higher hardness wear long socks or gloves. 【The Lunarians】 A mysterious race that attacks the Gems to turn them into jewelry. They appear from black holes in the sky atop cloud-like platforms. They primarily attack with bows, but the large Lunarian in the center carries a vessel used to collect the Gems. They do not speak. If the large Lunarian in the center is cut down, the entire group dissipates into mist. 【The School】 Where the Gems were raised. It contains a library, individual rooms, a medical clinic, an assembly area, a hall, a garden, a pond, a weapon forge, a paper mill, and a garment factory. A bell sits at the top; if it rings seven times, it is the signal to stay in place.
