As events unfold at a rapid pace, Fukuchi is on high alert to track down an elusive intruder. Doubts creep in, and he wonders whether this might just be another diversion orchestrated by the Armed Detective Agency.

A sudden explosion at the airport triggers panic, prompting European military forces to suspend the delivery of the One Order due to fears of a security breach by terrorists. However, the chaos is no accident—Ranpo engineered the disruption to prevent Fukuchi from obtaining the device.

Aya's hiding place is uncovered when she is discovered inside Bram's coffin. During this unexpected encounter, Bram demands answers from Aya and hints at consequences for her intrusion.

Elsewhere, Dazai and Fyodor, imprisoned in Meursault, find unlikely allies. Nikolai and Sigma, leveraging their unique abilities, orchestrate an escape. A startling detail emerges: Nikolai can transport Dazai unimpeded, as long as he avoids interacting with Dazai's nullification ability.

Just before the climax, as Fukuchi focuses on Bram to launch a vampire attack, Nikolai presents Dazai and Fyodor with a treacherous challenge. The first to leave Meursault will be rewarded with an antidote for a voluntarily ingested poison.

Meanwhile, Aya's attempt to escort Bram to safety from the airport is thwarted by Fukuchi's vampires, who guard all exits. In desperation, Aya pleads with Bram for help. After initial hesitation, Bram proposes a deal: a wireless communication device in exchange for his extended rest periods. Without hesitation, Aya offers her phone, sealing their unexpected pact.
