A brawling youth film about love, friendship and fisticuffs, set in the 1980’s. Ko-chan was once a decent and regular third year junior high student, concentrating solely on his studies, until one day a single event changed his life. From that point onwards Ko-chan gets involved in a lot of problems, he fights all through class and acts like a punk, while he still has a puppy love for his beautiful but uptight classmate Yamada. ~~ Adapted from the novel "Waruboro" (ワルボロ) by Gettsu Itaya (ゲッツ板谷).
