Kojo goes to Iblisveil Aziz in search of answers on how to defeat Veres Aladar, but Iblisveil only gives Kojo a vague answer. Kojo returns to the agreed place of the duel shorthanded and begins the duel.

With the help of La Foria and Veres Aladar, Kojo broke into the council and declared Itogami Island as his territory as the 4th Primogenitor and gained the right to veto the attack. But for him to be recognized for this, he must expel Vatler from the island and become a true ruler. Can Kojo defeat Vatler, who has absorbed the power of the Cleansing, and save Itogami Island from the crisis?!
