    Summary

    Two years after Dazai's death, Chuuya is the Boss of the Port Mafia, and things are going as well as anyone can expect. Until they're not.

    "What--?" Chuuya manages, the word thick and throaty, too wet, too obvious. He blinks: what he's seeing doesn't change.

    "Chuuya-kun, please come in," Mori says, conversationally. "If you could close the door behind him, Dazai-kun."

    Chuuya's head whips around; Mori at the desk had been enough of a shock, but Dazai, curled up lazily in an armchair with a book, looking like a petulant housecat as he stands up, still covered in bandages with one eye visible, is enough to make Chuuya feel almost nauseated.

    "Chuuya," Dazai says, the word a sing-song and nothing like the monotone way he'd said it when he was the Boss, "come on."

    Summary

    Dazai felt close to tears, he was so full. “‘S too much. I’m gonna die,” he wailed, taking one of Chuuya’s hands in his own and guiding it to his belly. “Need a massage,” he demanded, “please. It hurts.”

    Of course, Chuuya obliged, letting out a little catcall as he began to give Dazai some of the deepest belly rubs he’d ever received. That seemed to really get the younger, who accidentally let the tiniest, cutest hiccup slip. His face flushed an adorable shade of pink, and he mumbled an apology out of shame.

    He wasn’t really used to this whole concept to begin with, so even the smallest of unintentional noises had Dazai blushing like crazy. Chuuya found it hot as fuck, though. “Oh, baby…” he murmured, a wave of the most violent cuteness aggression washing over him. “Must be so stuffed. ‘M sorry, sweetheart… gonna make you feel all better, yeah?”

    Summary

    Chuuya never believed in yokai, demons and other paranormal stuff. It went against every scientific fact he had learned throughout his entire life and every one of his beliefs as a passionate of physics.

     

    Everything that has to do with supernatural forces is devoid of logic, you can't explain it with science and therefore — is impossible. Nonexistent.

     

    Demons do not exist. End of story.

    OR,

    Chuuya's stuck with demonzai. What could possibly go wrong?

    Summary

    Ever since a few weeks ago when Dazai admitted, after a hearty amount of whiskey, that he'd slept with one of his coworkers during the very early days of their getting-back-together process, this has become a part of their daily routine. An uncomfortable part for Dazai, but a part all the same.

    Bent over the end of the bed, ass up and legs spread to the empty room, he waits with his head resting on his arms.

    Or, Chuuya is more possessive than even Dazai knew.

    Summary

    🔞 When Beast Chuuya's world burns in the aftermath of Dazai's death, he tears through reality itself to find a universe where his partner still breathes—but the Dazai he discovers belongs to another Chuuya, one who has already claimed him with chains of loyalty and possession. Trapped between two gravitational fields of desperate obsession, Dazai surrenders to the only thing that might finally drown out his death wish: being claimed completely, filled by both monsters at once, and owned so thoroughly he forgets how to want anything else.

    Summary

    🔞 In the Port Mafia, owning a hybrid is as common as carrying a gun—pretty little creatures bought at auctions or traded between the rich, kept for comfort, obedience, and stress relief. Chuuya never cared for it, never understood why everyone else had one, until a failed mission leaves him unraveling at the seams. At Kouyou’s insistence, he attends an underground auction just to “look.” He plans to leave empty-handed—until he sees the final lot: a bandaged black cat hybrid adorned in jewels, sharp-eyed and devastatingly beautiful. Chuuya bids without hesitation, paying more than anyone dares challenge, and walks away with the strangest thing he’s ever wanted.

    Summary

    🔞 When an ability gone wrong throws Chuuya into a parallel universe, the last person he expects to find is Dazai—wearing the Boss’s coat and acting like he owns the Port Mafia. One argument, one broken elevator, and too many unanswered questions later, Chuuya’s temper snaps and suppressed instincts take over. Trapped between floors with a version of Dazai he doesn’t trust but can’t stop wanting, the line between hatred and hunger blurs fast.

    Summary

    Dazai is horny, or maybe he just needs to cling to Chuuya until he feels something—until he feels everything.

    “Want me to stop?” Chuuya pressed a kiss on the inner thigh before trailing lower, dragging the bridge of his nose along the place Dazai needed him most. “I could spend all night like this.”

    His hand spread across Dazai’s lower back.

    “A cigarette. A glass of wine. My fingers buried inside your pretty ass.”

    Another lick.

    “Or a toy.”

    His voice dipped lower.

    “Would you like that? Want me to fuck you with a toy?”

    Dazai forgot how to breathe.

    “Or I could pour wine right here and lick it up. I bet that combination would taste incredible.”

    “I want—”

    “I know.” The interruption was almost cruel. “Or you could ride me but I doubt your stamina would last.”

    Summary

    🔞 For a year, Chuuya has been catching Dazai before he can walk into walls, trip over furniture, or send himself crashing face-first into the floor. Dating a stubborn man who refuses to admit he needs help comes with certain occupational hazards.

    Lately, though, something has changed.

    Dazai's accidents are becoming suspiciously predictable. Every stumble seems to happen when Chuuya is behind him. Every fall ends with Dazai sprawled across a desk, a couch, or a kitchen counter while Chuuya desperately tries not to think about it.

    The worst part? Dazai appears completely oblivious.

    Chuuya is not.

    Summary

    BIRTHDAY FIC

    Dazai is an omega, but this is a secret he holds close to his chest. Everyone in his life has just assumed he is a beta or an alpha… including Chuuya. He had no reason to doubt this until the clutches of heat grab ahold of his partner before his very eyes.

    They are both 18 and in the port mafia, this is a birthday fic so it will be relatively Dazai-centric.

    OR

    Chuuya finds Dazai nesting in his bed and learns some things he’s been denying for a long time.
    Happy birthday Dazai.

    Summary

    "I think," Chuuya says softly, and his eyes are dark and fathomless like the depths Dazai has always been warned away from, "that you should come back in the water."

    -----

    After years away, Dazai finally returns to the waters of his childhood.

    Chuuya finds him.

    Summary

    "Chuuya, I can't-"

    "One more, baby, don't you want to be good for me?"

    Dazai whines at the taunt, but he nods his head against the pillows anyway, unaware of the tears that slip down his cheeks when he squeezes his eyes closed.

    Summary

    “Such a needy little thing, aren’t’cha?” The words are soft, almost like he’s talking to himself. He comes closer, though, padding from behind the couch so he can settle himself on top of Dazai.

    Yours, though,” Dazai whispers smugly as Chuuya clambers on top of him, his smile stretching so wide that his jaw aches. Chuuya’s hand finds it’s way to his hair once again, his fingers softly caressing his drooping ears.

    “Mhm, you are. My needy little kitty.” His voice drops into a sultry octave, his bright eyes piercing through Dazai’s skull. He arches his back, pushing up against the man on top of him in an effort to get him tangled closer.

    (if you get through Chuuya's lil' mental breakdown at the beginning then you'll get to the shmexy stuff, I promise. And also, I tried to make it all rough and tough but idk, it always goes soft in my head).

    Summary

    A (heated) reunion.

    "Surprised you're drinking that, you hate wine."

    "You don't have whiskey."

    "Well, I fucking hate whiskey," Chuuya hummed, drinking the rest of the wine within his glass, Dazai noticing those cogs within his mind as the other man looked back and forth between the bottle and the cup. Eventually, he picked up the bottle and took a swig.

    "Taking it easy, I see," Dazai smirked, letting the glass rest on the table once more as he inspected the other man's frown. Perhaps he could tell him. Perhaps he couldn't tell him. Was it because he couldn't or that he wouldn't? He wasn't sure.

    "I thought you were dead," Chuuya muttered, taking another swig out of the bottle, hand tightly wrapped around the neck of it, clearly biting down on his tongue to avoid screaming.

    "I didn't want you to come looking for me."

    Chuuya & Dazai get to know one another again, essentially.

    Summary

    There was a person with a writhing tail inside the net, short, wavy dark brown hair disheveled around their face, reddish-brown eyes quickly scanning the surroundings, their frail body, riddled with wounds, writhed on the deck.his wet tail hitting against the floor, trying to move but the more it tried, the more entangled they became in the net, their tail, covered in bright blue scales, flapping from side to side.

    He couldn't believe his eyes.

    So the legends were true.
