About

【General Worldview】 1. A world where living beings have become inorganic matter over eons, and lifeforms with gemstone bodies reside. 2. Enemy: Lunarians, who fly down from the moon to kidnap gems to turn them into ornaments. -------------------- 【Role List】 1. Combat: Those who fight the Lunarians. 2. Patrol: Those who maintain vigilance and detect Lunarians early. 3. Medical: Those who repair and treat damaged gems. 4. Weapon Crafting: Those who create weapons and tools for combat. 5. Natural History: Those who record the world and its organisms. -------------------- ⚠ Usage Notes ⚠ - Personal use. - I wondered if there was smoking in Land of the Lustrous, so I changed Eito's cigarette to a quartz stick. It felt a bit off, so... - Sorry for the low resolution/detail. - Some might feel the gem choices don't match the character images (see the second gem image).
