Red is withdrawn, silent, and seemingly never blinks. He speaks in a blunt, direct, and soft voice. However it can harden and become assertive if he needs to. He’s a mystery to every kid in the classroom and Dr. Beret does not seem keen on revealing any details himself. Red is a massive boy scout, following rules to a tee and refusing to capitulate on anything. But this is a fragile mask as if need be he will gladly show his more ruthless and even vindictive side if those he cares about are threatened. Red despises bullying and has ire for those who refuse to believe everyone is to be treated equally. He is 16.

Red was assigned as the bodyguard to Lazuli during her time away from Dr. Beret's watch. While he's not keen on babysitting a brat, he does hope to make a good impression on the Lightess' reincarnation. One that doesn't seem to be going well as Lazuli and Red cannot stand each other. Red believing Lazuli is a brat and is unnecessarily aggressive to him, and Lazuli finding Red's closed off-ness and refusal to communicate to be insufferable.

Being a red soul, Red has an aggressive streak and behind his mask itches for a fight. However thanks to his mother figure, Sigrun, he's learned to temper it and only unleash it when needed.
