Prushka 1/7 st Made in Abyss

Spoilers tonen

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.

She later dies, as Bondrewd has made her into a cartridge, and gives birth to Riko's white whistle.
