Hatta sensei is a timid and quiet teacher at Shirokin.Though he says very little, he does care about the school and its students. Like Yamaguchi, he wants to have faith in the students for the future
Hatta is often seen in the background among the many other faculty members. He really took his voice when he showed concerned for Tsuruta to avoid him getting expelled. Tsuruta had just returned to Shirokin from his suspension and advised the boy to stop engaging in fights.
When the school came under threat of closing down, Hatta offered to help and mentioned he once took karate. He and Tsuruta voluteered to be in karate competition. Though Tsuruta lost at the eighth round.
