Soukoku 

Meaning Double black the name was given to Chūya Nakahara and Dazai Osamu when they were paired together in the port Mafia, before Dazai left. In English the name meaning is Twin Dark.

Soukoku is also the ship name between Chūya and Dazai, it’s practically cannon within the anime. The anime it’s from is titled Bungo Stray Dogs

There’s a lot of evidence for Soukoku

They’re are called Soukoku because they were able to destroy an entire organization overnight, isn’t that cool?

soukoku 

The most popular ship in the Bungou Stray Dogs fandom. Kind of a love-hate relationship between Dazai Osamu and Nakahara Chuuya

I ship soukoku so much!! They are, like, the ultimate OTP.
