He is the eldest son of the Hinata family and the younger brother of Natsumi Hinata.

Currently a first-year junior high school student (having advanced from the sixth grade of elementary school in the original work), he serves as a secondary protagonist and the primary human protagonist of the series.

Along with Natsumi, he was one of the first humans to discover Sergeant Keroro. Although Keroro was initially wary of humans, he quickly bonded with the boy, and the two began spending so much time together that they could effectively be considered partners.
