Korrin Kim is a mercenary and a former inmate of Contrition's Figure. During the incident in the prison, she was trapped with Blueberri Jin and Soft Stone, and played a sort of three-person chess game with them using one of Declan's Corrective's poems.
Later, after Blueberri saved her life, they became friends.
She has very dark black skin, with white lines marking her face and arms. She wears a necklace made of six concentric rings, each bigger than the last. Her hair is styled to go up and out, like wings.
