Umihisa (Rio) had become the leader of the Ibaraki delinquent world, but because her father had been cheated out of all his assets, she decided to leave the delinquent world and transfer to the same prestigious school where her cousin, Hitoe (Minami Aiyama), attends, aiming to marry a rich man. However, instead of changing her attitude, Umihisa goes to school in a delinquent girl uniform from the 80s, spits on her teacher, and behaves badly... Then, Hitoe goes missing!

After the internal split, Kazuma Morisuka (Show Aikawa) charges alone into the Kinshishi-kai and dies in a blaze of glory. A year after his brother’s death, Misao (Kazuki Namioka) no longer appears at the Tenkichi-gumi headquarters. Meanwhile, the now-dominant Kinshishi-kai faces a string of attacks targeting only their executives. The power balance in Yokohama begins to shift— and just then, their sworn enemy Baba is released from prison. Baba rallies the Kinshishi-kai to crush the Towada Family once and for all. But at that moment, the long-hidden Misao finally makes his move.
