Jun Kitagawa
Jun is a friend of Yuichi's who sits behind him in high school. Before long they even start making odd jokes, such as the fact that they always wear the same clothes to school due to the dress code. Viewers do not see a lot of him in the first anime adaptation. Jun has a crush on Kaori Misaka and will often follow her around despite Kaori's dismissal of his romantic affections. He is seemingly there for little more than character development, as well as being one of the male characters with a name.
Jun's main involvement in the story is in Mai Kawasumi's arc after the event at the ballroom dance. The student council president, Kuze, wanted to expel Mai from the school for what happened at the dance despite her not being the direct cause of the damages. Jun, who was on the council that organized the dance, makes it seem that he knew all along that Mai would put on her "show" for the other students, though had no idea that it would get out of hand. This puts most of the blame on him, and thus Mai gets off the hook. While Kuze does not really believe this, he concedes to this single defeat, though does not want to easily back down from the situation. Another small direct involvement related to Jun is at the beginning of Kanon's story when he is the one that first spots Shiori Misaka standing outside in the snow during school.
