BUCCHIGIRI?!

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.

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.

Akutaro sees potential in Arajin and asks him to join NG BOYS. Arajin finds the offer tempting but is disturbed by the bloodthirsty look in the members' eyes. Matakara confronts Akutaro about the war being a set-up and is jailed so he cannot warn anyone.

Despite Matakara's efforts, the fight between Kenichiro and Marito begins. Taking advantage of their position, the NG BOYS enter the battle between Minato Kai and Siguma Squad. How will the war end, and what will happen to Arajin and Senya's training?
