Shinsha

The only gem who goes on night patrol. Due to their body producing Mercury (which is harmful to gems and living things), they are isolated and insecure. They hate fighting and hate to be seen. According to Rutile, Cinnabar has an extraordinary amount of talent and combat ability, but is too much to handle due to their uncontrollable poison. Cinnabar's silver poison gathers faint light at night, which keeps them awake and aware while night patrolling. According to Kongou, the night patrol is something Cinnabar came up with themselves. They used to spend their time during the day in Hollow Cape, waiting for the Lunarians to take them since they thought they may at least be of use to them. They are knowledgeable about things other gems don't know about. Phosphophyllite was recommended by the gems to see Cinnabar for the encyclopedia. After accidentally hearing their secret and wish, Phos promises to help Cinnabar find a job more suited to them than night patrol, saying, "a fun job only you can do." When encountering Phos each time, Cinnabar seems doubtful of their words, but they are the only gem they regularly speak to. Although they try not to show it, they have a tiny sliver of hope that Phos will be able to fulfill their promise. Cinnabar is able to pull out an abundant amount of mercury. They're able to manipulate it in the air, from a distance, and around them. They seem to not be in full control over it and sometimes release it without wanting to.
