Kumigami Hiyo

Daughter of a famous family of doctors, she is extremely polite and always speaks in the very polite desu/masu form. She always calls Sasamaru “dannasama”, and is always thinking about supporting and serving him, essentially being almost like the perfect wife. Occasionally she’ll show her more stern side, primarily to Harutsuge as punishment for jokes going too far.

Spoiler

Her name from previous life is Kikuyo (菊世)
