Minato Kai and Siguma Squad, two rival gangs at Ichizu High School, are embroiled in a bitter power struggle. As a transfer student, Arajin Tomoshibi has no interest in getting involved; instead, his priority is finding a girlfriend. Fortunately for him, he is placed next to Mahoro Jin, the prettiest girl in the class who also seems to like him. However, she has an overprotective older brother, Marito—none other than the combative leader of Siguma Squad. Moreover, Arajin's reunion with his childhood friend, Matakara Asamine, spells trouble since Matakara is a member of Minato Kai. With his rotten luck, Arajin also accidentally awakens the genie Senya, known as a Honki Person from ancient legends. Senya takes a shine to him because of the young man's fervent aspiration—despite it only being the loss of his virginity. While Arajin would be the first to flee from a fight, Senya lending him his powers helps the lovesick boy to hold his own against the likes of Marito, although this only raises the interest of both gangs in recruiting him. As the turf wars heat up when a third gang joins the fray, Arajin's involvement may be unavoidable.
