Prushka is the adoptive daughter of the White Whistle Delver Bondrewd. She was born in the Abyss and, as such, has never been to the surface.

Prushka is a young girl with short white and green curly hair and glowing red eyes. Her attire appears to be somewhat influenced by the clothing of diving suits. She wears a green coat and gloves on top of a white shirt, as well as a big hat on her head she almost never removes.

Prushka is a cheerful and amiable girl who loves her adoptive father very much. She is incredibly devoted to him, and would do anything to help him, holding him in a higher regard than anyone else
