Mirga ... a girl with tall figure, long black hair and the same class as the protagonist. Glasses with metal frames are interested in playing the piano and doing math, and a pair of slender fingers suitable for playing the piano are above the average person in any field.
Teddy has short hair and big eyes that turn flexibly. The little protagonist is a one-year-old school girl, nicknamed Teddy. I feel like a lively little animal, like a squirrel or a kitten, with a lively, cheerful and confused personality. I want to learn math well, but I don't know what to do, so I find the protagonist and hope to teach her.
