Eager to become the strongest in Shonan, hot-blooded delinquent Ikki Kurokami begins his third year at Tsujidou High, the alma mater of the legendary Oni-Baku duo (Eikichi Onizuka and Ryuuji Danma of Shonan Junai Gumi and GTO). Ikki aims to join the Shonan Seven, the victors of a tournament where seven representatives from each high school in Shonan compete to determine the strongest school, with seven matching beautiful motorcycles as prizes. However, to reach that goal, he must also face any and all challengers vying for the same position.
