Prushka (Furry) is a Narehate interpretation of Prushka from Made In Abyss.
Narehate Prushka is not a canon Made in Abyss character, but she has been featured in some official illustrations by the manga's author Tsukushi Akihito. Most notably, she has been depicted in a bonus illustration in volume 5 of the manga receiving the Blessing of the Abyss and becoming a Narehate.
