Tsutomu Rokutanda
About
In the New Year's episode, he meets the girl of his dreams, Yayoi-chan but he forgets to get her name, address or the name of her school. He is devastated. He is sitting in a park, feeling rejected in the Valentine's episode when he overhears a guy turn Yayoi down. She sees him, recognizes him and they share the chocolate that she was going to give the other guy. We see them again in episode 58 on a double date with Ginta and Arimi. It looks like he is going to be a good guy after all!
When Ginta and Arimi break up in a later episode, he teams up with Miki to get them back together. By this time, it really looks like he is maturing.
