Kayoko Nagato

Kayoko is a student of the same class as Doremi in their 3rd year. She had transferred to Misora Elementary at the same time as Onpu but due to unknown circumstances she stopped coming to school ever since. This would lead to Doremi trying to figure out why after she encounters her one day on the way to school. She likes to do her work slowly but well and has an interest in things like plants and astronomy.
