Chapter 99

At the Portway to the Sky,Part 8 (空ノ港二テ其の捌,) is the 99th chapter of the Bungo Stray Dogs manga.

Summary
Kenji rescues Aya and Bram and effortlessly overwhelms the airport vampires. Just as Ranpo deduced, the airport has turned into Fukuchi's unassuming battlefield, hence having sent Kenji to bring Aya and Bram to a safe space. Bram also nonchalantly beckons Kenji to work for him amidst Aya's protests, though Kenji respectfully declines. Noticing a Hunting Dog arrive, Kenji analogizes that he must protect them, the sheep, from the approaching wolf, Tetchō.

After figuring out Fukuchi's strategy, Ranpo has also sent Atsushi, one of their quickest members, to chase after Aya and Bram before Fukuchi and his allies get to them first. He then spots a crying girl in a corner, thinking it to be Aya. As he comes up to her, she assures him that she has finally found her lost companion. "Aya" turns out to be a disguised Teruko, who chokes Atsushi.

Remembering Tetchō as the one who stabbed him from their previous escape, Kenji urges Aya and Bram to retreat somewhere safe, unsure whether he can defeat the Hunting Dog. Aya and a reluctant Bram then retreat. Tetchō clarifies that his business is with the Agency and questions what they have done with the missing Jōno. Kenji also does not know himself and suggests they look for him together. Tetchō gladly accepts his assistance, until he recalls that Jōno was last seen with Fukuchi when he was kidnapped by a vampire, reverting back to his claim that the Agency is behind Jōno's disappearance. Not planning to waste anymore time, Tetchō strikes Kenji with his sword.

Atsushi struggles against Teruko's grip in spite of his tiger strength, managing to get a device from his pocket. Teruko slams him to the ground and swipes Atsushi's device to prevent him from contacting others, only to find a video of Tachihara on it. Before his fate, he filmed his ultimatum claiming that the Agency is innocent before cutting off contact. Teruko, though still ambiguous towards the Agency, asks Atsushi their strategy, but he instead asks her to cooperate with them first. In response, Teruko instructs him to bring her to their strategist. Despite not having assurance that Teruko is one of those like Tachihara who broke the rules of the Book, Atsushi directs her to Ranpo, believing that he would be able to convince her.

Meanwhile, Kenji gets stabbed by Tetchō's quick blade but manages to grip it back and hurls Tetchō using his elongated sword, forcing him to unhand his blade. The two soon get locked in a battle of physical strength, resulting in a deadlock and impacting their immediate vicinity. Tetchō, asserting himself as a Hunting Dog, gradually gains the upper hand and overpowers Kenji, blasting him off the wall.

Trivia

 * Kenji initially tells Aya and Bram that he shall bring them to a "safe ability space". This is left ambiguous whether it refers to Poe's space or Lucy's space, considering how the two have been aiding the Agency since their regathering. However, since their most recent hideout is in Anne's Room despite having an interim office made from Poe's ability before, Kenji may be referring to Lucy's space.
