A boy who lives and attends school in Sotoba. He hates living in the village and prefers to be in the city. Originally a city dweller, Natsuno reluctantly moves to Sotoba with his parents when they wanted a change of environment. He often exhibits a cold exterior, especially disliking Megumi Shimizu's presence, who has a crush on him and is obsessed (to the point where she stalks him). He is kind and friendly toward those whom he considers his friends (Tohru, Kaori, Akira and Tohru's younger siblings).

Natsuno is one of the two main protagonists in the series.
