Kenji Sakuragi is a poor lawyer and ex-motorcycle gang member looking for an opportunity to boost his career. His chance finally comes with the nearly bankrupt and notorious Ryuuzan High School, referred to as "baka gakkou" (stupid school) by some. There, he sets up a special class that aims to prepare students to take and pass the entrance exam of Toudai.

Zaizen Takashi passes his entrance exams at the top of the heap, and starts his first year in junior high school at Dojuku Gakuen, a 130-year old, highly advanced institute of higher education. The day after the entrance ceremony, "the secret" of the school is revealed to him, which concerns the existence of an "investment club," consisting only of the top student from each of the 6 grades.Its club members have a mission. They must invest from a capital of 300-billion yen and yield a profit of 8%, which is their annual goal. This is why Dojuku Gakuen, boasting the highest standards of education in all of Japan, is tuition free.
