Nemu

Ratio's best friend. She's a girl who lives at the bottom of the World tree, in the Ice realm. Ratio and Nemu are very close. Nemu loves the food Ratio and Jamon cook for her. Nemu comes from a village built in an old spring but it is now covered in thick ice crystals so she can't go back home. Nemu has an illness that causes her body to crystallize, so she always sleeps in a bed that floats in the middle of a spring.
