Souheki

Souheki is the slash ship between Osamu Dazai and Ranpo Edogawa from the Bungou Stray Dogs fandom.

Canon
Both Ranpo and Dazai are members of the Armed Detective Agency. Hailed as the Agency's sharpest detectives (双璧, Sōheki?, lit. "Double Jade"), Dazai and Ranpo are the organization's intellectual groups. Dazai first met Ranpo as a newcomer in the Agency, during which he witnessed Ranpo's Super Deduction firsthand. Only to find out that Ranpo is a non-ability user after touching his hair while deducing and failing to nullify it. This earned Dazai's great respect towards Ranpo's genius intellectual prowess and pure deduction ability. It also shocked Kunikida after finding out about it for the first time through Dazai. As a result, Dazai and the rest of the Agency members respect Ranpo despite the way he behaves in the Agency.

Later on, Dazai's and Ranpo's collaboration are explicitly shown while planning the Moby Dick infiltration. Their conversation, through Atsushi's perspective, merely consisted of audibly vague ideas. Though the both of them seem to have a mutual thought process and understanding as to how they shall go about their scheme, which ultimately led to their success.

This unseen dynamic apparently persists in various instances. For example, after the Yokohama fog incident, specifically when Ranpo returns back to reality and ambiguously calls out to Dazai while musing on the events he predictably deduced. In one of their cases on Standard Island, Dazai made sure to contact and update Ranpo after sensing in advance that the agents would be in trouble, hence leaving the rest of the matter in Ranpo's hands and eventually saving the Agency members and many people on the island.

Quotes
"He’s like a legendary detective character in a novel - no, for the character’s book ends when the case is solved. Then I don’t think any fictional character could hold a candle to Ranpo’s powers of observation which let him find the bomb without going to the crime scene or meeting the suspect."

Fanon
Souheki isn't extremely popular. However, it isn't necessarily a rarepair neither. The ship salied due Ranpo being one of the few people that Dazai respects. Soukoku and Ranpoe commonly rival this ship. In A03, the ship has 440+ works. It is the 2nd most writted ship for Ranpo. It also has a reasonable size of fan arts.
