Yuna's boy friend. While he is knowledgeable and considerate, he is bullied by Koji and his friends because of his timid personality, but he is often protected by Yuna. He is also one of the students of the ''Chitama style'' karate. He had an unbalanced diet, so his body was not strong, but thanks to the rice balls Reuben made, his unbalanced diet was cured. In the second series, he once bought the wrath of a youkai named ''Mabuitokkae'' for disturbing his sleep, and had his soul swapped with Stitch.
