Fujimura-kun Mates

Synopsis

Fujimura is a loner delinquent at his school. Feared by his classmates since the first day of high school, he's had no friends and usually ditches class. But even his standoffish nature can't hold up when a class president with a few screws loose comes after him! And two more class presidents. They're a few cards short of a full deck too. (Actually, he's more like the tsukkomi in a world of boke.)
