Arajin dreams of a sweet high school life at a new school, where the Minato Kai and Siguma Squad gangs fight to be on "top." Arajin meets the charming Mahoro, his childhood friend Matakara, and then a legendary djinn Senya, and his fate begins to change.

Arajin surprises everyone when he uses Senya's power to land a punch on Marito. Marito falls in love with that fist and tries to convince Arajin to join Siguma Squad, but Matakara asks Arajin to join Minato Kai to continue their Honki training together.

Siguma Squad goes to Minato Kai headquarters to avenge their injured comrades. The Minato side claims that their members were jumped by Siguma. Sensing something afoot, Matakara asks Mahoro and Arajin to persuade Marito to prevent an inevitable gang war.
