Houseki No Kuni (Coloured)

In the distant future, a new life form known as Houseki, or gems, emerges. There are 28 of these beings, and they must defend themselves against invaders from the moon who seek to capture and use them as ornaments. Each gem is assigned a specific role—some become fighters, others healers. However, one gem named Phos is left without a duty until their master, Adamantine, finally gives them a task: to compile an encyclopedia.
