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.

Despite Matakara's protests, Arajin joins Siguma Squad to please Mahoro. Marito takes Arajin out and tells him that they're headed to a raunchy welcome party full of girls. When they arrive, Arajin discovers that the party is not at all what he imagined.
