    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

    The walk from Bar Lupin to the apartment was a long one.  

    Although he only lived fifteen minutes away from there, those fifteen minutes felt like hours for Sakunosuke Oda and the (former) port mafia boss Osamu Dazai.  

    Neither of them said anything – they both knew it wasn’t needed. A few whiskey shots was enough to send dominoes cascading. They were always arranged in a perfect line. How weird was that?

    Summary

    🔞 During a mission, Chuuya Nakahara is struck by an ability that forces him into an artificial rut. Before anyone realizes how severe the effect is, a completely oblivious Osamu Dazai returns from an overseas assignment and walks straight into the situation. Overwhelmed by the ability’s influence and driven by heightened instincts, Chuuya immediately pounces on Dazai, turning what should have been a routine homecoming into a chaotic and highly personal crisis.

    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

    He doesn't know.

    The dress helps, obviously. The loose curls around her shoulders help. The absence of bandages, the makeup, the softer posture, the simple fact that nobody expects Dazai Osamu to willingly present herself as a woman. But still some irrational part of her had always believed Chuuya would recognize her instantly. Apparently not.

    The situation is, objectively, ridiculous. Dazai finds herself enjoying it far more than she should.

    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

    Her body and mind move at different speeds. One has already accepted defeat while the other stubbornly refuses to follow. One tells her that nothing matters anymore. The other reaches desperately toward the next moment, the next breath, the next heartbeat. It is Chuuya who helps her reconnect them now.

    Summary

    The guards grab Dazai, and he relaxes his body to prevent the injuries that tensing up would give him. Dazai feels his ability try to activate: it stutters and fades away almost immediately, the vampirism a symptom and not the root of the problem, and Bram Stoker several thousand miles away.

    "If you're anticipating that this will stop me–" Dazai begins, and Dostoyevsky cuts him off with an easy smile.

    "I don't need to stop you. Merely delay you further," Dostoyevsky says, voice easy and sweet. "They'll stop you in whatever way they see fit, although I don't know that violence is their preferred method. Since they can't subdue you simply by turning you…"

    Dazai's smile comes out more of a grimace, he's certain. "You're an even nastier fellow than you let on, you know."

    Dazai is afraid to look away, as though a single blink would make her loved ones disappear, as though the bliss would end.

    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

    "Who disturbs my slumber?" a voice booms out, into the water, very clearly able to be heard, which isn't how the physics of sound and water work, but that's a problem for later, because Dazai recognizes the voice instantly.

    "Why are you sleeping in the Yokohama harbor?!" Dazai says, back, wasting most of the rest of his oxygen as he swims backwards several feet. Of course, for Dazai, the words just come out as a vague series of muffled sounds and air bubbles.

    Despite Dazai moving backwards, the tentacle he'd been touching – because that's undeniably what it is – snaps out quicker than Dazai can track in the dark water, wrapping around his waist and pulling him closer.

    Lovecraft frowns. "I have seen your face before."

    Summary

    🔞 With the King of Hell away dealing with a rebellion, Dazai quickly grows bored and decides the rules are more like suggestions. Sneaking into Chuuya's forbidden vault, he steals a powerful ceremonial cane and spends his absence playing "Acting Authority," throwing Hell into chaos for his own amusement. It all works out wonderfully—right up until Chuuya comes home and discovers exactly what his troublesome angel has been doing.

    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

    Of course, out of all the people in Yokohama, it is Akutagawa who finds her. And of course he finds her in the middle of one of Chuuya's games. Do not blame her for giving the monster a name. The only thing that has cared whether she lived or died in months deserves at least that much.
