Sora's friend and classmate. They are in the same art club. Natsumi has made a number of puppets which she uses as study aid (for memory), problem-solving and substitute friends at times. Totally spontaneous, Natsumi is a perfect complement to Sora, and she's also highly interested in her friend. She has a dog, Kuro, that has two speeds: "hyper" and "off."
