Chapter 25 (Vertical Comic)

Chapter 25 is the twenty-fifth chapter of the Bungo Stray Dogs (Vertical Comic).

Summary
Back at the station, Sugimoto explains in an interrogation room that he didn't plan to shoot Yamagiwa. Yamagiwa had been looking into a corruption case involving some politicians, as she looked into the case it seemed that a large senator was also involved. However, this senator had a mole in the police force just in case to get rid of possible evidence found, Sugimoto being the mole. Sugimoto says that when he was training to be a police officer, he failed the entrance exam 3 times, the senator helping him pass the exam to become an officer if he would follow his orders.

The scene cuts to a flashback of Sugimoto and Yamagiwa, Sugimoto trying to convince Yamagiwa that they're serious but Yamagiwa brushes him off. Sugimoto pulls out his gun, telling her to hand over the evidence, or else the senator will hire a hitman on her and get her killed. Yamagiwa tells Sugimoto to put down the gun as she knows he won't shoot her, Sugimoto agrees, putting the gun to his head. Yamagiwa panics, running over to Sugimoto and fumbling around to grab the gun when Sugimoto accident fires, shooting her in the chest, whispering something before falling dead in front of him.

Ranpo says that if such information came out Sugimoto would've been fired, so he then called the senator and followed his instructions to disguise the crime as a mafia hit, destroy the evidence Yamagiwa had collected, delay the discovery of the body by placing it into the river. Minoura asks where the evidence Yamagiwa collected was and that they must expose the senator and avenge Yamagiwa. Ranpo steps behind Sugimoto, asking Sugimoto is he would like him to guess Yamagiwa's last words, "I'm sorry.". Sugimoto cries, saying the evidence is in the drawer of this desk.

As Dazai, Atsushi, and Ranpo are thanked by Minoura before they head back to the agency, he apologizes to Ranpo for doubting his ability. Ranpo smiles, saying that if they ever come across any more tough cases he'll let them use his ability with a discount.
