Summary
It was supposed to be a simple raid. It wasn’t supposed to end with a new being in Dazai’s arms. It wasn’t supposed to end with the bits of humanity he chased away from his heart reviving. Dazai was supposed to be the Demon Prodigy, the most ruthless and hell-bent man of all of Yokohama and Port Mafia history, and A-157 was supposed to be just another experiment that would bend under Dazai’s command like every other before.
But the human, a soul broken much like Dazai, reached his hand out to him, and Dazai couldn’t help but reach back. -

Summary
Chuuya Nakahara reluctantly takes on the lead role of the Nutcracker in a ballet, dismissing it at first as childish and unimportant. However, as he delves into the story—a broken wooden man transformed into a prince because someone believed in him—he begins to resonate deeply with the character. The Nutcracker’s journey mirrors Chuuya’s own: discarded, powerful, yet yearning to be seen as more than a vessel or weapon. Despite trying to remain detached, Chuuya crosses his fingers before stepping on stage, silently hoping to be understood. Through his performance, he expresses his unspoken desire to be believed in and accepted, not as a tool, but as a person. Kouyou, watching from the shadows, sees the truth: for the first time, Chuuya let himself hope.

Summary
After Mori Ougai passed down the Mafia to his executive - Dazai Osamu, many want to try their hand at intimidating or striking the Port Mafia.

Summary
Seven-year-old Chuuya Nakahara, a subject of a cruel experiment, rebels against Professor N, the scientist obsessed with him. After overhearing disturbing truths about his existence, Chuuya lashes out and flees into the forest, only to be hunted down. As the professor’s voice echoes through the trees, an unbearable pressure builds inside Chuuya, overwhelming him with fear and causing his powers to stir uncontrollably.
When Professor N catches him, his voice is unexpectedly gentle, lulling Chuuya into submission as he leads him back to the lab. But the moment they return, punishment awaits. With cold precision, the professor breaks Chuuya’s legs, shattering him both physically and mentally. Yet, in a twisted display of affection, he cradles the sobbing child, whispering words of reassurance. His voice is soft, almost fatherly, as he declares:
“You should practically call me father.”
Through his pain, Chuuya realises the chilling truth—he is trapped, bound not just by the facility, but by the professor’s twisted love. And no one is coming to save him.

Summary
Chuuya’s life is turned upside down when his mother introduces a mysterious man named Nakahara as his new babysitter. Although Chuuya feels something is off, he soon finds himself kidnapped and taken to a secret lab where Nakahara, now revealed to be a scientist, conducts horrific experiments on him. Chuuya is subjected to repeated torture, including near-drowning in a tank and electric shocks. Isolated and desperate, he longs for his family, unaware that they are searching for him but have found no trace. Over time, Chuuya witnesses the horrors of the facility, including clones of himself and failed experiments, leading him to discover he has been used as a test subject for activating a dangerous power known as Corruption. Stripped of his identity and humanity, Chuuya becomes the first successful experiment in Nakahara’s twisted project, left as a living weapon rather than a child.

Summary
I’m not sure what to put here for this, but basically Chuuya and Dazai escaped the lab together and met Oda on the streets. Now, Oda takes care of them.
I’m debating making this another series, but this is essentially just a little drabble piece of how they would meet Fukuzawa and Rampo after being with assassin Oda on the streets for a year or two.

Summary
Everyone is able to write on their skin to their soulmate once they turn fourteen, but Chuuya Nakahara never believed he had one. Ever since he was seven, he was trapped in a lab to be tested on. It was all he could remember, he had no life outside of it. He believes himself to not even be human, just a monster harboring something dark inside of him.
So he’s shocked when a few months after his birthday, he gets a message written on his palm.
Inspired by some lines in the song ‘IDK you yet’, which you’ll see then.
