A slow-burn horror-comedy loosely inspired by "Hell Screen" by Ryunosuke Akutagawa and a suspiciously specific cruise ship route. After a mysterious but undoubtedly disastrous outing, the members of the Armed Detective Agency find themselves on a luxury cruise. They think they're here on a mission, but Atsushi Nakajima knows the truth. This is all actually an elaborate scheme to get the stressed detectives to go on vacation. Sure, he has no idea what actually happened on said outing, but it's his job to make sure things go smoothly. Plans to relax and unwind however are ultimately ruined when a certain Port Mafia is discovered to also be onboard. Secret guests, shared rooms, and impromptu weddings are already more than enough for poor Atsushi to handle. But it's not until when people start disappearing to things really start to go wrong. Beneath its sunny facade and cheery smokescreen, could it be that something a lot more nefarious is happening aboard this ship? And more importantly, is Akutagawa really the only person able to help him out?! -- Meanwhile, Chuuya, a man who cannot dream, finds himself suddenly afflicted by nightmares. Dazai tries to help. Bungou Stray Dogs and all its characters belong to Kafka Asagiri and Sango Harukawa Bolded quotes are excerpted from "Hell Screen" by Ryunosuke Akutagawa (the real one).

On a dark and frosty Christmas Eve, cursed mistletoe began appearing all over Yokohama. Despite being under strict orders to remain inside, the members of the Armed Detective Agency one by one find themselves on the streets of the city. And more than one, underneath these malicious leaves with someone they really had no intention of kissing...ever.

Chuuya Nakahara returns from an overseas venture to find that everyone has become obsessed with him. With the help of a perplexed Dazai (whose nullifying ability may be the reason why he's the only one not overcome with Chuuya-mania) can Nakahara get to the bottom of this mystery? Or will everyone love Chuuya....forever?
