And in a world of violence, the only person you can trust is the one you want to kill the most. · · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · · {DISCLAIMER} The characters Dazai Osamu & Chuuya Nakahara (along with others) belong to the anime/Manga series "Bungo Stray Dogs" THIS IS MERELY A SHIP BOOK · · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · ·· · ─ ·✶· ─ · · #1 in dazai 11/24/2025

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.

"Since how many days you haven't slept , chuuya ?" "That's none of your concerns, dazai!!"

Double Black is put into a villain reformation program at UA as its first unwilling participants. (Though they have more control than UA thinks.) _+-*-+_ Reputations lead to rumours, and rumours have a tendency to run free. So when rumours of the infamous Double Black reach the Pro Heroes, the organization of the shadows is in the eyes of the light. So now the Pros Focus is on the big bad mafia. But if they were to focus on reforming Double Black, then the situation would be put in Double Black's control. And it would be disgusting to not save these orphans? Who had no guide in the world, who were forced and manipulated by evil men to be heartless killers by a brutal, unforgiving world? I mean- have I mentioned they don't have parents?

Dazai Osamu was the youngest Port Mafia executive in history; an alpha referred to as a demon even by his colleagues. Except that he isn't an alpha, and he's certainly not in the Port Mafia anymore. Now, he's not really sure what he is, but he hopes he can add "good mother" onto his resume someday. And he needs to figure out how to fit Chuuya there with him. [omegaverse au of canon]

After years of silent endurance under Mori's thumb, Dazai Osamu finally breaks. Wounded, overstimulated, and unable to speak, he shows up at Chuuya's door in the dead of night - not as a Mafia executive, but as a shattered boy who doesn't know how to ask for help. Chuuya, still tethered to him by something deeper than he'll admit, takes him in without question. What begins as a night of tending wounds slowly unravels into something far more fragile: trust. As Dazai recovers in secret, hidden from Mori's reach, the two rediscover each other in the quiet. Trauma leaves its mark - in broken speech, haunted silence, and the missing eye Dazai refuses to explain - but Chuuya refuses to let him fall back into darkness. Even when Dazai proposes marriage in the middle of a breakdown, even when grief and guilt threaten to drown them both, Chuuya stays. Together, they plan their escape - from the Mafia, from their past, from a city that never let them breathe. With Ango's help, they fake their deaths and disappear into a life neither of them believed they could ever deserve. A life with a home. A shared bed. A bath filled with lavender oil. A prosthetic eye that lets Dazai be seen without being dissected. And for the first time in years, they begin to learn what safety feels like. But healing is never easy. And love, no matter how deep, doesn't erase the scars overnight. This is a story of survival. Of choosing each other. Of saying stay and meaning it. And of two broken souls building something whole in the quiet. So what would happen if both joined the ada? And what would happen if Mori demands Dazai back after the prison arc?

A few months after Chuuya Nakahara had joined the Port Mafia, Dazai Osamu decides to strike a deal with him, one to soothe his lingering desires... were they really just partners anymore?

CSR: THE DEVIL'S TEMPTATION "You've been very disobedient, kitten." Dazai mutters dangerously, "I must teach you a lesson you'll never forget." Chuuya was an orphan, and when the orphanage that he loved got burned when he was 7 years old, he got adopted by a kind and mysterious man that he calls "Master," except that "Master" is a seven-year-old demon prodigy named Dazai Osamu... and Dazai is not as kind as people think he is.
