Nemuru has purple hair and her eye colour is purple. She is seen wearing a red ribbon that is tied into her hair with a yellow-red pinwheel-like bow on top.
On her school days, she wears her school uniform which consist of a white shirt with a red tie and a white skirt. When she is hunting, she wears a ceremonial outfit with a wolf mask and wields a scythe.
Nemuru is close friends with Mana. The first time they met was when Mana saw the village council and almost fell out off her wheelchair. Nemuru helps her and gives her the Usaeru doll after seeing Mana adoring the doll.
