Episode 56

At the Port in the Sky (Part 2) (空ノ港ニテ（其の二）,) is the 56th episode of Bungo Stray Dogs anime series and the sixth episode of the fifth season.

Synopsis
Fukuchi's plans and the Agency's attempts to thwart him escalate, and Aya comes face to face with Count Bram. Meanwhile, Nikolai and Sigma move to rescue Dazai and Fyodor from prison, but Nikolai has more than rescue on his mind...

Summary
Fukuchi retracts his hunt for the witness and surmises that he is merely being distracted by another ploy of the Agency. British Intelligence agents also fly to the airport to deliver One Order; Ranpo assures Atsushi that they can obstruct the delivery by using their status as terrorists to their advantage and make the military escorts retreat.

At that moment, Kunikida sets off an explosion nearby, cutting off Fukuchi's contact with Tetchō and Teruko. The British Intelligence escorts also detect the explosion and abort the delivery mission. Aya turns relieved after narrowly escaping from Fukuchi but is crossly faced by Bram, whose coffin she has hidden in. With their plan in play, Ranpo remains assertive of their success but is also apprehensive should Fyodor likewise make his move to disrupt their strategy.

Amidst this unease, the British Intelligence agents suddenly bleed out and eventually got killed, compelling Tetchō to take down the plane and let Fukuchi retrieve One Order from the wreckage. Though Ranpo naturally feels bested by Fyodor's doing, Fukuchi is also unable to open One Order's containment, courtesy of Ango's interference per Dazai's plan, which is to allow the United Nations to unlock One Order only when the vampire armies strike.

Meanwhile, an intruder enters Meursault and trounces the prison's forces. Dazai and Fyodor decide to escalate their game in exchange for one of them dying. Nikolai, accompanied by Sigma, arrives and breaks them out of their cells. After Aya and Bram acquaint with one another, Aya takes Bram away from his coffin. Once Fukuchi discovers Bram's disappearance, he orders vampire officials to shut down the airport, find Bram, and kill the thief.

Nikolai enjoins Dazai and Fyodor in his prison break duel, requiring them to take a lethal injection, escape Meursault before they get killed, and acquire the antidote upon winning. Sigma is visibly fazed at their oddity, especially with Dazai's and Fyodor's enthusiasm towards the game with their lives at stake.

As Aya and Bram get stuck hiding from vampire officials, Aya attempts to take out the Holy Sword on Bram, but to no avail. Though he initially notes her foolishness, Bram questions her motives for fighting for justice. Aya recalls being deemed a failure of a woman by her father and answers that she only has determination, therefore needing all the help she can get. Despite her eagerness, Bram is certain that she can't provide him a radio anyway in return, but Aya alternatively lets him listen to music on her phone, much to Bram's bliss.

Manga and Anime Differences

 * The anime slightly shortens the British Intelligence agents' conversation. In the manga, the pilot initially gets unnerved at the eyepatched agent's pessimistic metaphors regarding the world's current situation.
 * In the manga, it is mentioned that Kunikida used his notebook to make a bomb and cause the airport explosion, though the anime simply mentions that he has already "blown up the fuel truck".
 * While Ango talks to the prime minister, Taneda is with him bedridden in his office in the manga. In this episode, Taneda is shown in another location, and Ango merely glances at him through his computer.
 * After Ranpo remarks how Fyodor is still dangerous, the manga depicts him claiming Dazai as the only one who can defeat him, the winner of which can be decided on who can eliminate the other first. This remark is omitted in the anime.
 * The anime does not include Dazai's and Fyodor's interaction in their cells, including eating their breakfast, trying to give each other an extra egg and salt, respectively, and commenting on the intrusion's noise upstairs and their meals.
 * When Dazai tells Fyodor that it is time for one of them to die, the manga shows him with a serious expression, while the anime depicts him saying it in a rather lightsome manner.
 * Unlike in the manga, the anime omits Dazai, wondering if Nikolai was the one who set off the racket in the intrusion upstairs outside their cells.
 * The manga includes two instances of Aya's memories of her father reprimanding her. This episode does not include the first instance of Aya being hit on her cheek arguing with her father.
 * In a minor difference, the anime does not show Aya as an infant as briefly illustrated in the manga.

Trivia

 * The voice actor for Senior Escort Officer B, Kazuki Ura, was credited incorrectly, listed as "浦和　希" instead of "浦　和希". This shall be corrected in the Blu-ray/DVD release.
