Phos from Land of the Lustrous
Phosphophyllite, or Phos for short, is the main protagonist of the anime Land of the Lustrous. She is part of an immortal, humanoid species called the Gems that inhabit the only landmass left in the world. Her sole duty was to make a natural history encyclopedia, but there’s been very little progress. Phos is the youngest Gem, who is clumsy, yet desires to be useful. For instance, she promised to help another Gem named Cinnabar find a suitable job. She wears a standard uniform and can be recognized by her teal green features.
