As Kyouka fights her past demons, the threat of a three-way war between the Armed Detective Agency, the Guild, and the Port Mafia looms. With each side fortifying their defenses, who will seize the initiative and land the first crushing blow? After an attack by the Guild's fellowcrafts, the Agency's chances for survival might just be gone with the wind...

The Armed Detective Agency's genius sleuth Ranpo hits a wall after a skill user with the frightening ability to eliminate criminal evidence sets the stage for the most mind-boggling murder case yet. What's more, as the Agency members continue to solve the riddle that is Dostoyevsky, they discover the evil conjurer is just the tip of the iceberg...

The Armed Detective Agency receives an anonymous request-and it's asking for Kyouka's help by name. But during her investigation with Atsushi, ex-Guild member Montgomery keeps mysteriously getting in their way! And as another old for defies death while seeking a triumphant return, a newer enemy-the sinister Dostoyevsky-bares his fangs against both the Armed Detective Agency and the Port Mafia. As he threatens to slowly but surely swallow the dark underbelly of Yokohama, how will this devil of a man alter the playing field...?!--EndFragment--

With only minutes to stop the Moby-Dick from crashing down on Yokohama, Atsushi encounters his nemesis, Akutagawa! However, the face-off turns into a three-man battle when Fitzgerald enters the fray. Can Atsushi and Akutagawa counter the Guild leader's extravagant ability in time to stop the white whale's descent...?!!--EndFragment--

Still on the run from the law, the Armed Detective Agency is forced to strike deals with the unlikeliest of allies. As Atsushi negotiates with Fitzgerald to use the "Eyes of God" and Dazai is locked in a battle of wits against Dostoyevsky, the Port Mafia offers to shelter the others-but only if Yosano comes over to their side. With nowhere else to turn and the military's Hunting Dogs closing in, Yosano must come to grips with her dark past...

Atsushi and Akutagawa butt heads! Dazai and Chuuya also butt heads! Whether it’s the Port Mafia getting in on the virtual reality boom or the kids at Bungo Day Care figuring out how to deal with a ghost, the cast of Bungo Stray Dogs have their mature moments...and some childish ones, too. But through it all, one thing’s for sure—no one in Yokohama is getting any work done today!

With the heads of the Agency and the Port Mafia on the brink of death due to a “cannibal” virus, the vicious rivalry between the groups rears its head once more! As the fearsome Akutagawa and former assassin Kyouka face off in a fatal battle, a rare confrontation between the cocky Chuuya and genius detective Ranpo threatens to disrupt the city’s peace. Meanwhile, Kunikida and Atsushi are off to search for a cure, but will they make it in time or will they be doomed to fall before their old nemeses?
