A second year in high school. She was the siblings' neighbor and childhood friend. She and Isaomi mutually love one another, so they've always appeared like a young married couple. However, the reality is that they're still at the stage of platonic acquaintances. With a kind and earnest personality, she excels at her studies, sports, and housework. With her looks, she's well-known as a beauty even at other schools, but the excess growth of her breasts has planted a seed of worry in the girl herself.
