Phosphophyllite (フォスフォフィライト, Fosufofiraito)
Known as “Phos” for short. One of the weaker jewel people, with a hardness of 3.5. Declared as too weak for battle, Phos is tasked with creating an encyclopedia logging new information. Despite this, as well as their immaturity and clumsiness, Phosphophyllite desires to enter the battlefield in order to be acknowledged by their peers and prove their worth. As Phos keeps experiencing hardships in battle, their limbs, along with their memories, are gradually lost and replaced with other elements. At the same time, their personality begins to change gradually with each replacement, as well as their perspective changing.
Cinnabar (シンシャ, Shinsha)
An aloof jewel person who is even weaker than Phos, with a hardness of 2, but carries a powerful poison in their body. Because this poison taints the environment and erases memories stored inside affected jewel shards, Cinnabar is kept on night watch, but yearns to escape the night.
