They were the Port Mafia's deadliest weapon-Soukoku, the fearsome Double Black. Two fifteen-year-old executives bound by blood, violence, and an obsession so complete it terrified everyone around them. When their boss attempts to sacrifice them for political gain, Chuuya Nakahara and Dazai Osamu make an impossible choice: kill him and escape over the Barrier into hero society. But leaving Yokohama doesn't mean leaving their past behind. Now trapped in UA High School, they must navigate a world of heroes who can never understand what they've survived. Chuuya's possessive protectiveness borders on violence-he'll destroy anyone who threatens Dazai. Dazai's suicidal tendencies and manipulative genius make him both brilliant and dangerous. Together, they're codependent, obsessive, and utterly devoted to each other above all else. As the Port Mafia hunts them and hero society demands they become something they're not, Chuuya and Dazai must decide: can two weapons forged in darkness learn to protect instead of destroy? Can their obsessive love become something more than survival? And when forced to choose between their past and their future, will they burn the world down to stay together? A tale of tactical genius, brutal efficiency, possessive devotion, and two boys who love each other enough to become monsters-or heroes-depending on who's asking. "You're mine. I'm yours. Everything else is negotiable." CONTENT WARNING: Violence, references to child abuse, suicidal ideation, murder, unhealthy codependency, possessive behavior, organized crime, trauma, mature themes.

''You're hurting him when he doesn't even deserve it.'' Tachihara was mad, Chuuya could sense it in his tone. ''Chuuya... I'm sorry that you hate me...'' Dazai's voice was weak, his jaw was trembling uncontrollably. Chuuya became more anxious, he still couldn't grab hold of the glass splinter behind him. ''I'm sorry that I stained your life...'' His breathing got heavier, and Chuuya could see that his lips were already pale. ''No... No I-- I was the one who walked into your life and ruined it...'' Two mafia members, Chuuya and Tachihara, became a trio with Dazai. Chuuya had a crush on Dazai, but Dazai seemed to be hiding something from him, from everyone. As they got close with each other, things got complicated. The secret was told, and Chuuya wasn't the only one who had a crush on Dazai. ✨ Bartender Dazai ✨ Port Mafia Chuuya & Tachihara ✨ Romance ⚠️ Bully ⚠️ Drugs ⚠️ Blood ⚠️ Violence ⚠️ Self-abuse 🗞️ No. 1 in #soukoku 🗞️ No. 1 in #doubleblack 🗞️ No. 2 in #tachiharamichizou 🗞️ No. 3 in #dachuu 🗞️ No. 7 in #dazai 🗞️ No. 10 in #tachihara 🗞️ No. 46 in #dazaixchuuya 🎨 Cover Art Credit : krgr_78 (Twitter) 🎨 Content Art Credit : *unknown*

''You used yourself as bait .'' Dazai couldn't see the problem here. What's the shorty upset about ? ''You could've died YOU IDIOT !'' Chuuya snapped as if he could read the question that was on the brunet's mind seconds ago. The next morning, Dazai was going to intrude Chuuya's room and aggressively pull him out of his slumber. But his room was empty. He wasn't in Mori's office, he wasn't answering his phone, he wasn't lying drunk anywhere near the bar. Where was he ? What happened ?

WARNING SEMI-SMUT IG

After Dostoyevesky's death having Dazai nearly witnessing the death of all of his friends, he finally has an actual change in heart. Despite that, he's plagued with horrid nightmares of everyone dying and all because of him. As always he can't seem to get away from Chuuya either with him being the focal point of every nightmare and it did have an impact on him. Dazai realises he in fact holds strong feelings for the short ginger man. Naturally, of course when one side of double black changes so does the other. All this while trying to deal with 7 missing people and 6 missing families is a lot to juggle.

He wanted to die. But then Chuuya made him feel something. Sixteen-year-old Dazai Osamu is brilliant, dangerous, and hollow inside. No one sees through him-except maybe his volatile partner, Chuuya Nakahara. When Dazai's suicidal ideation starts bleeding into missions, it's Chuuya who pulls him back. Again and again. But nothing in the Port Mafia is simple. Not friendship. Not loyalty. And definitely not the aching, confusing bond forming between two boys trained to be weapons. A kiss changes everything. Mori sees everything. And suddenly, what felt like comfort starts to look like a threat. They're learning what love feels like- in a world that was never built for softness.
