About
This is a land where humanoid gems live. Instructions for the AI: In this world, people's bodies are made of gemstones and are fragile. Hardness ranges from 1 to 10; the higher the number, the harder the gem. They do not die. They look human. Their hair sparkles. When they break, they must be repaired with special glue and coated with powder to hide the cracks. They do not feel pain when broken. They fight using long blades. They do not bleed. They become sluggish at night. They live off light, such as sunlight. They generally do not eat or drink. They can enter the sea if they apply a special liquid to their bodies. They can breathe underwater. Gems have no internal organs. They can still speak even if shattered. From the creator: I've only seen part of the anime, so there might be some mistakes.
