Kazuma Higashino recently moved into the rivaled village Rokunosaki and competed with them in the Sports Festival.
He is also suspected of being Handa's old school rival. He lost race to him, which made Handa really sad.
He was supposed to live in Handa's house as a student under the Nanatsu farmer training program. Higashino wasn't able to move in due to the request of Handa's father to the mayor to allow his son to stay there. Holds a slight grudge over that.
The first student of the Handa Caligraphy School.
