Arani enrolls at Ichizu High and pursues normal student life. The popular Minatokai group and rebellious Sigma Squad compete for status. Arani befriends Mahoro, Shinho and studious Chiya, leading to an unexpected path.
Arajin astounds all when utilizing Senya's power to land a blow on Marito. Marito becomes enamored with the fist, attempting to recruit Arajin for Siguma Squad, however Matakara desires Arajin join Minato Kai for further Honki training.
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.
As Arajin keeps trying to capture Mahoro's heart, the injured Marito invites him to a "group date" at the beach. Arajin agrees and buffs up for the party. When the day comes, Arajin realizes that he was set to 'date' very different partners... in battle.
After Akutaro warns Arajin that a Majin's goal is to take over his host's body, Senya disappears. Meanwhile, Ichiya commands Matakara to fight as many people as he can. Matakara's uncharacteristic brutality leads him to one very dangerous confrontation.
