Chapter 58.5

Sunday Tragedy, Part 2.5 (後編,) is the second part of 58th chapter of the Bungo Stray Dogs manga.

Summary
The rest of the Agency arrive at the location with only five minutes left. Kunikida notices the military police arrive and asks Kenji to stop them as one of Gogol's conditions not to have anyone else interfere. Gogol reappears to his hostages and frees only Tonan from his captivity. Gogol also hands him a phone to call for rescue. Meanwhile, Ranpo notices surveillance cameras in the room together with Taneda, suspiciously recalling how they were none when he entered the building. He then realizes his frame-up as a criminal caught on camera, later being asked by the police outside to surrender.

Kenji overturns the military's tanks and stops the arriving troops. Military authorities deduce that an organization is conspiring with the Decay of the Angel, since said organization had advanced knowledge of the supposedly secret meeting of the government hostages. Tanizaki, Kunikida, Kyōka, and Yosano prepare their plan to infiltrate the room and save the hostages.

Despite having a few minutes to spare before the appointed time, Gogol instructs his cohorts to activate the chainsaws and take their hoods off, to which military snipers ready themselves to identify the criminals' faces. As the hostages' bodies are halved, the criminals reveal themselves to be the four Agency members themselves. Much to their confusion despite not breaking down the door yet, they find themselves inside the hostages' room, with Gogol tied up on a chainsaw chair. Stating his desire to be freed, Gogol then screams as his body is halved, with Tonan contacting his troops that he knows the criminals' identities. Ranpo also calls Kunikida to warn them to get out of the room, but he is too late, as Tonan names the Decay of the Angel to be the Armed Detective Agency.
