Description：In the season of falling petals, lawyer Sakuragi Kenji (Hiroshi Abe) is on his way to Ryuyama High School. He happened to meet Yusuke Yajima (Tomohisa Yamashita) who was fighting with gangsters, and Naomi Mizuno (Masami Nagasawa) who tore up the failed test paper. Both of them are third-year students at Ryuyama High School. In fact, Ryuyama High School has become a shabby high school that is ridiculed and forgotten due to poor management and low admission rate. Sakuragi Kenji's visit this time is also to deal with the school's application for bankruptcy. However, Sakuragi Kenji is not willing to get things done in a hurry. He used to be a biker gang and wanted to do something that would make a sensation in Japan. A passionate idea sprouted in his mind: to lead the stupid students of Ryuyama High School to enter the number one university in Japan - the University of Tokyo. So, Sakuragi Kenji and English teacher Ino Mamako (Kyo Hasegawa) set up a school to study for a while.
