Based on a manga by Taiyo Matsumoto, Toshiaki Toyoda's 'Blue Spring' is a story about high school anarchy in the long, bruised-and-battered tradition of Be-Bop Highschool and Fudoh: The New Generation. In a school surrounded by misleadingly picturesque cherry trees in full bloom, it's the students who set the rules while uncooperative teachers are dangled from windows.
