All About Lily Chou-Chou follows two childhood friends, Shusuke Hoshino and Yuichi Hasumi, from the end of their junior high school run until the beginning of high school. The film has a discontinuous storyline, starting midway through the story, just after high school begins, then flashes back to junior high and summer vacation, and then skips back to the present.In junior high, Hoshino was the best student in school, but was picked on by his classmates. He was skilled at kendo, and had an attractive young mother. Yuichi, on the other hand, was a quieter boy who fell in love with the music of the odd musician Lily Chou-Chou. During a group trip to Okinawa, Hoshino had a traumatic near-death experience and his personality changed from good-natured to dangerous and manipulative. In high school, he takes his place as class bully and shows his newfound power by ruining the lives of his classmates.
