Before disappearing, Ranpo attempts to inform Atsushi about Kamui's ability but isn't able to properly deliver the message as he had been already transported into the novel.

Battle with Kamui
Atsushi stands before Fukuchi with no allies around him. Just then, Akutagawa arrives on Atsushi's aids as per Dazai's orders. Atsushi and Akutagawa soon face Fukuchi together in a battle. However, even though Akutagawa and Atsushi combines their power and skills, they are still overpowered by Fukuchi's ability and equipped weapon. Towards the end of the battle, Fukuchi invites Akutagawa to train under him as a member of the Hunting Dogs and orders to kill Atsushi. During the event, Akutagawa also reveals that he won't able to live much longer due to his lung disease indicating that with the time left, he cannot disappoint Dazai. Agreeing to Fukuchi's invitation and order to kill Atsushi, Akutagawa uses the opportunity to charge towards Atsushi in order to trick Fukuchi and uses the opening to activate Beast Beneath the Moonlight–Rashōmon: Black Tiger's Supreme Claw, which allows Atsushi to sever both of Fukuchi's arms.

However, Fukuchi changes the outcome of events allowing him to sever Atsushi's arm and slashing Akutagawa instead, which he reveals is the power of his sword that can cut through time and space. Fukuchi fully uses the sword's power to once again anticipate Akutagawa's misdirection attack prior to their escape which eventually results to Atsushi and Akutagawa's defeat, which also left Akutagawa dead.

Atsushi is able to escape from the scene using a submersible and is rescued by Ango shortly after. After the battle, several guards came rushing to the area as Fukuchi orders them to track the terrorist who escaped in a submersible.

With Fukuchi's threat to sear the Holy Sword attached to Bram into his brain, Bram obeys Fukuchi and bites into Akutagawa, eventually turning him into a vampire.

After Akutagawa turns into a vampire, a vampire outbreak begins to spread, turning some mafiosi to vampires. As a witness of the said event, Tachihara reports to his fellow Hunting Dogs members giving them the idea that the Armed Detective Agency is behind it.
