She is the mother of Chibi.
She is an adult Asian black bear, which has typical features of the species. She has a white crescent-shaped patch of fur on her chest.
She and her cub were hiding from Monsoon. When Monsoon spotted them, they tried to escape, but he followed them, telling them that this was his territory, and that trespassing was not appreciated. When they try to run away, her cub trips, and she tells him to run and not to look back. She tries to defend her cub from Monsoon, but it is a futile attempt, since she was moments later decapitated by his claws. She's later buried by Shion, Sirius and her newly dubbed cub, Chibi.
