A large-scale power outage hits the heart of Bayron City's Downtown. It was a D Hazard caused by a giant caterpillar-shaped Demonically Possessed. With detailed information on Demon Possession that he obtained from somewhere, Shu decides that this is a job that "must be done" and uses Ayano for insider info to pull strings. As Shu's company is about to win the bidding war at a discount, significant new information about the Demonically Possessed is revealed. Those who took the situation most seriously decided to suspend bidding and expelled Shu from hazard prevention measures.

Kisara keeps her distance from Shu's apartment since she saw the memories of Shu and Ayano's time in the warehouse. Reversely, happy for Kisara's absence, Ayano takes good care of Shu as she relishes feeling like they are lovers. Kisara, who checks out the situation via social media, is getting increasingly more annoyed. But behind the scenes of this love triangle is a storm of violence that blows into Bayron City. Just who is this blonde beauty who appears out of nowhere wearing a nun's habit? And what is her goal as she repeatedly commits senseless acts of brutality by invading scene after scene of Demon Hazards?
