The deuteragonist of Doraemon.
A lazy boy who will put anything he's not interested on hold until it's too late, which resulted into his family's doomed life in the future. Thus, his great grandson sent Doraemon back to the past to help him to become a responsible man. He usually wears thick rounded glasses, a yellow polo shirt, and blue shorts.
Despite his seemingly terrible responsibility and intelligence (as seen by a running gag about him almost always getting a score of 0 on his monthly exams), he can turn into a very dependable person when someone needs help. He's also notable for his amazing sharpshooting skill.
