Summary
After leaving the Port Mafia and joining the Armed Detective Agency, Dazai Osamu unknowingly begins dressing in a way that mirrors Oda Sakunosuke, the man whose death pushed him to abandon his old life. At first, the Agency only notices that Dazai looks unusually put-together—his coat neater, his vest pressed, his posture calmer—but gradually they realise it isn’t just a change in fashion. His habits, stance, and quiet attentiveness resemble someone who once lived with purpose and responsibility.
The truth surfaces when Ango recognises the resemblance and names Oda, revealing that Dazai’s new appearance echoes a dead man who shaped his moral compass. Dazai himself doesn’t consciously choose this transformation; his body clings to Oda’s presence as a way to survive, to remember, and to honour the standard Oda left behind. In the Agency, Dazai is no longer dressed like someone courting death, but like someone learning how to live—wearing the silhouette of the man who taught him how.

Summary
Chuuya wanted to kill himself.
After his boss died, corruption activated. He never knew how far corruption could bring a person. How else?
He always had a companion on his side to bring him down to earth. A partner. A friend.
But now that he's gone, Chuuya's gone rogue. Nobody knew what corruption was like once it swallowed you inside and out. But apparently, death is not the only destination.That's what he realises when he wakes up in the Armed Detective Agency. To a familiar face with a bolo-tie and a beige coat.
In a completely different world.
While Chuuya was making amends with his first love's death, welcoming this new version of him. This new way of life.
His former boss' plan was still under operation.
He didn't lie when he told Chuuya that he'd never leave his side. Because a certain somebody is invading the detective's very own body. And he's got him on a kill switch.
Or
simply put, Beast Chuuya is in the canon universe and Beast Dazai is trying to invade Ada Dazai's body cuz he possessive af.

Summary
“Who are they?”
He already knew who I meant. His eyes flicked over to them, and so did Albatross’s—though it was the youngest-looking one, the bandaged boy, who looked up first. He locked eyes with Lippmann for half a second, then turned that gaze on me.
It was…flat. Cold. Not curious. Not hostile. Just bored.
I stared back, tilting my head slightly, mismatched eyes locked on his black ones. I didn’t look away. But then Lippmann turned back to me, and I broke the gaze.

or, i had nothing better to do than put Dazai Osamu and Chuuya Nakahara into Twilight.

Summary
Dazai’s obsession with Odasaku runs far deeper than friendship or romance—it is a desperate, all-consuming fixation born from years of loneliness and pain. After Odasaku showed him unexpected kindness and shelter following a failed suicide attempt, Dazai clung to him as a lifeline in a harsh, uncaring world. Though Odasaku remains distant and indifferent, Dazai’s need to protect and preserve him drives him to unimaginable lengths—exploring countless alternate realities in search of a way to save Odasaku from death. His fixation transcends logic or mutual affection; it is a raw, unbalanced hunger for the one person who ever made him feel valued, even if that person never truly reciprocates. Ultimately, Dazai’s obsession becomes both his salvation and his undoing, defining his existence in a world that offers him nothing else.

Summary
Dazai, still haunted by the death of his friend Odasaku, discovers solace in the unfinished stories Odasaku left behind when he departed the Port Mafia. Each night, he reads these stories—some complete, others not—finding comfort in the familiar words that reflect his own struggles with loss and regret. Through Odasaku’s writing, Dazai is reminded of their bond and the unspoken emotions between them. These stories become his refuge, a way to hold onto his friend’s memory and to process the loneliness that persists in the absence of Odasaku's presence.

Summary
On the occasion of Odasaku's birthday, Dazai, Odasaku, and Ango gather at Lupin’s bar for a night filled with laughter and camaraderie. Dazai, ever the instigator, captures the moments with his camera, pulling his friends into playful antics that bring joy to the air. Amidst the fun, Odasaku and Ango share a shy glance, their hands entwined, prompting Dazai to tease them mercilessly.
As the evening unfolds, Dazai entertains them with exaggerated tales of their past escapades, filling the bar with lightheartedness. However, the atmosphere shifts when a distant voice begins to echo Dazai’s name, growing louder until everything around him fades away. He suddenly finds himself standing alone at Odasaku’s gravestone in the rain, haunted by memories of that joyful night.
Chuuya arrives, pulling Dazai back to reality and expressing concern for his friend. Their conversation leads to unspoken feelings about the past, with Chuuya encouraging Dazai to reach out to Ango, who still carries a connection to Odasaku. But Dazai, grappling with guilt and resentment, rebuffs the idea, leaving a heavy silence between them as they stand in the rain, reflecting on memories of joy and loss, and the unbreakable bonds of friendship.

Summary
“Hello Chuuya,” the young man spoke, ruby red staring into ocean blue. “My name is Arahabaki.”
------------
Or basically Dazai leaving the mafia and Chuuya accidently making a deal with Arahabaki to take a human form and act as his new partner. 4 years later, Dazai is out of hiding and absolutely seething at who the fuck this beautiful crimson haired man is and why the hell he stole HIS dog.
Additional upcoming lore
- Yes Arahabaki is canonically beautiful
- Verlaine is the only person Chuuya tells because he has no one else to go to. Commence brotherly bonding, forgiveness and utter confusion because Arahabaki is a walking energy bomb.
- Chuuya and his god bonding cause why not <3 (attempted ice cream runs are made and Arahabaki gets fascinated with human food lmao)
