Sakuragi Kenji is a destitute lawyer and one-time member of a motorcycle gang trying to guide failing high school students with an average score of 36 into Japan's most prestigious educational institution, Tokyo University (Toudai). For no other reason than Sakuragi's personal ambition, he has advertised his intention to produce 5 successful Toudai applicants from the students of a nearly bankrupt failure of school.

A few years ago, a group of struggling students at a low-ranked high school made it into Japan’s top college, Tokyo University, thanks to Kenji Sakuragi, a down-on-his-luck lawyer-turned-teacher. But since he left, the school has been on a downward spiral. Now they’ve wooed him back, and he’s determined to turn things around again – this time with the motto: “Times are tough! So get a move on!” Students are overwhelmed with choices and desperate for something to hold onto. With his profound belief in their ability, Kenji offers a ray of hope.
