Gaiden Chapter 4.10

Ministry of Justice / Morning / Sunny ⑩ (司法省本館／朝／晴天 ⑩,) is the tenth part of the 4th chapter of the Bungo Stray Dogs Gaiden manga.

Summary
As Yoshino's body falls off to a crossing, much to the passing civilians' shock, Kyōgoku indulges that the agent, owing to his ability, has been possessed by itsuki, a that possesses and drives people to hang themselves to death. Ayatsuji cuts him off with a threat to kill him whatever it takes if abilities such as his own cannot affect him. Kyōgoku, however, is unfazed, while the rest of the Special Division agents also get possessed and point their own guns at themselves.

Kyōgoku once more asks for Kubo's release in exchange for the agents' lives, which Ayatsuji begrudgingly accepts. The detective then instructs Ango to release the engineer; in any case, he assures that they still have a second chance at him, with photos of him now publicized around the city, a fact which Kyōgoku acknowledges.

Tsujimura soon notices the railway track shaking, and a train arrives amidst its suspended operations. The unaffected Special Division agents then take cover and restrain their possessed subordinates from firing their weapons per Ango's directive, while Kyōgoku instructs Ayatsuji and Kubo to board the train. Ayatsuji warns Kyōgoku not to regret having him take the train, to which Kyōgoku replies that he has anticipated such response.

Trivia

 * Kyōgoku mentions the folklore of itsuki being written in Taiping Yulan and Strange Tales from a Chinese Studio. Taihei Gyoran is a Chinese  encyclopedia compiled by officers under Li Fang, which was commissioned during the Song dynasty during the reign of Emperor Taizong.
