Orphanage Director Accident Case

The Orphanage Director Accident Case is a case originally forwarded to Ranpo.

Prologue
Ranpo orders Atsushi to handle the job instead.

Case
Atsushi arrives at the scene in replacement for Ranpo. Tanizaki briefs Atsushi about the victim and shows him the illegal handgun the victim has on him - and indication that he may be looking for someone but was killed instead. Atsushi notices the victim holding a magazine article, however the important part of it was torn. Unable to deduce the case themselves, Atsushi tells Tanizaki that Ranpo told him to look for the flower shop if he ever runs into trouble. Later on, Tanizaki updates Atsushi that they have an identification of the victim based on his prints. Atsushi screams in shocks as he see that it was the orphanage director.

Shocked by the news, Tanizaki reveals that the director is looking for him which made Atsushi relieved in a sense that the one behind his nightmares are gone. Atsushi still tells that that they need to figure out why the director died. Atsushi speculated that he may have been waiting for someone specifically for a Port Mafia member and he might've connections to the underground considering that the director has an illegal handgun. Tanizaki then proposes to ask Dazai if he knows something.

Soon after, Atsushi meets with the informant which turns out to be Akutagawa and reveals that the case was an accidental death. It turns out that a former mafia armorer was supposed to buy the gun from the director when he witnessed the collision. Akutagawa further tells him that the director was going to sell it and use the money for a future purchase. Soon after, Atsushi learns about the director's past.

Tanizaki arrives with obtained evidence as to why the director was in Yokohama - he came after seeing Atsushi's gossip-mag photo spread to encourage him.

Resolution
After the case, Atsushi visits the director's funeral from afar. Dazai approaches and consoles him. He further tells Atsushi that the director wanted to sell his gun and buy a bouquet of flowers for Atsushi but died in an accident before the exchange.
