Myriad forces continue to converge on the frozen Lake Kannawa. Asagi and Lydianne, riding in the pink tank, are joined by Ibliss, a high-ranking vampire from the Warlord's domain, after he rescued them from flying demons. Gajou and Shio carry the comatose Nagisa across the frozen lake, seeking a haven for her.

Shio defies Azama. From afar, Shirona incapacitates the lower level cultists. Okiyama appears on a wyvern and leading a second one to retrieve Azama and they flee. Azama joins the other confrontation and first betrays Ueyanagi, transforming him into a golem, and then attacking Yuiri, triggering a distraught Glenda to transform and fly off with Yuiri, Kojo and Yukina.

After the terrorist incident on Itogami Island, Kojo and the others are helping with the Island's recovery. On the other hand, Asagi, who gained popularity with the public for preventing hacking in the past incident, works as an ambassador for revival activities for the Island Management Corporation. However, Kojo feels like something is off when he sees Asagi on the big screen.

Kojo and the others go to rescue Asagi, who was imprisoned on the 0th floor of the Keystone Gate. Kojo is worried about Himeragi's poor condition, but Himeragi goes with Kojo nonetheless. What was waiting for Kojo and Himeragi on the 0th floor?

Itogami Island had returned to a peaceful state and Kojo's party was getting excited about the upcoming Valentine's Day. Meanwhile, Kojo sees Asagi getting into a car with one of Vatler's subordinates, and starts to get suspicious. Grenda, who was with Shio and Yuiri, is attacked by Veres Aladar, the Imperial Council Chairman of the Warlord's Empire. Grenda flees to Itogami Island, where Kojo is located.

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.
