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?

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

Smut between Chuuya and Dazai, soukoku
Dazai looks down at the small red head, bound in ropes. His dick spilling with precum as he squirmed around on the bed. Osamu chuckles to himself as he slowly undressed himself infront of Chuuya.
“Maybe don’t be naughty next time chuuya~ or I wouldn’t have to do this~”
Chuuya whines.
“T-touch me dammit~!”
Chuuya yelps out as 2 fingers are pressed inside of him. Eyes rolling back, bucking his hips onto the taller males fingers, god it felt too good.

“Oooh~ hmgh~ f-fuck I want your dick more~”
“Beg” Dazai smirks at the ginger, and he sighs, “fine. P-please daddy~ please fuck me please~! I need your big fucking dick in me, I need it~! I’ll be your cumslut!~”
Osamu takes out both of his fingers and slowly presses his dick inside of Chuuya.

Chuuya gasps and lets out a little scream as dazais big cock enters his tight hole.

“Too b..big~!”

“You’ll be alright~“
Osamu begins pounding relentlessly into the small male, making the bed shake. Chuuya, moaning and screaming out, threw his head back and let dazai take over his mind and body.
Dazai holds onto his neck and began to push deeper into him, hitting his pr*state over and over again. It was too much for Chuuya to handle.
“Cumming~!!! O-oh fuck daddy t-t-there~!!! Please A-ahhh~!!!”
With that, the ginger spews his seed all over both of their stomachs, gasping for air. Dazai cums right after him, making sure his cock was deep inside. Dazai slowly pulls out, enjoying what’s left of Chuuya. Soukoku smut
