Yusa’s stepmother is a supporting character in Yuki-iro no Karute. She is Kashima Yusa’s stepmother and the very person responsible for destroying her family. She seems to love flashy styles, dyeing her hair blonde and going out in what is known as “bodycon” fashion. She is a character who evokes the feel of 1990s Japan.

She has absolutely no interest in Yusa and, resenting her, sends her to live at the protagonist’s hospital, which is far from home. She is quite the nymphomaniac, with a penchant for bondage and scat play, which she secretly enjoys.

She is not a romanceable character in the game; players can only occasionally catch a glimpse of her perverted activities.
