Also known as: 越谷小鞠
Character from Non Non Biyori.
She has Green Eyes, and very long Brown Hair with Asymmetrical Bangs, Antenna Hair, and occasionally, Two Side Up. She also wears the Asahigaoka School Uniform when attending school. Short and physically underdeveloped for her age, her height is said to be significantly less than 140cm (4'7"), which makes her the second shortest main character despite being the eldest girl.
Miyauchi Renge often calls her by her nickname Koma-chan, which she dislikes being called. In spite of her easily upset nature, she's well behaved and a studious student, which contrasts with her lazy younger sister Koshigaya Natsumi.
Voiced by Asumi Kana.
