Editor-in-chief Koizumi requests help from Yamaoka. Koizumi's son Norio, a last-year student in jr. high, is not studying for his exams, and instead stays out late, drinking alcohol and getting into trouble. Koizumi believes that, since Yamaoka is a former delinquent, Norio might listen to him. Yamaoka takes Norio to a bar where Yamaoka is greeted by two intimidating men who Norio believes are Yakuza.
