Suzuran Boys High School has always gathered a lot of delinquent boys, but none of them can become the leader. Until the appearance of the transfer student Takiya Genji, he With the help of graduate Tong Quan and other bad boys, he became the boss of the new power "GPS" in Suzuran High School, known as the "King of Beasts"

The "Serizawa Legion" led by Serizawa Tamao was very unconvinced, and had a fierce battle with Takiya Genji and the others, and in the end it was Taki Gu Yuanzhi won. Takiya Genji challenged Megumi Hayashida, known as the strongest man, but failed. A few months later, Fengxian Academy's "Killing Corps" decided to violate the agreement and send the assassin Mito Ryu to Suzuran. Originally, there was a big battle between Linglan High School and Fengxian College, but this battle reduced the power of both sides, so the two sides made a truce agreement. Takiya Genji only cared about the victory and defeat with Hayashida Megumi, and didn't care about other things, which made "GPS" face the situation of disintegration. He didn't expect that Suzuran High School was facing an unprecedented crisis.
