## History

### Fifteen Arc

He was a young child, living alone in an orphanage with only one companions to talk to. His younger sibling, Kyūsaku Yumeno. One night, he aimlessly paces around his room after the recent disappearance of his little sibling. Having no idea where they were, he was put under an infinite amount of stress that was too much for him to handle. Not only that, but he sustained from a few months ago, forced to have his tongue stapled. Relentlessly pacing was enough to tire him out, so he decided to sleep it off until the next dreadful morning. However, he instantly woke to the scent of smoke in his room.

Quickly getting up and looking outside, Tadao was met with screaming children and the orphanage staff trying to usher them out alive. He was left to watch in horror, until he made an important decision that would soon change the course of his life. To stay. He already struggled prior with his colder attitude and unfriendlyness compared to the other kids. So, staying in his room, he let the fire kill him, changing his fate and opposing the backstory of his counterpart from the original universe. The original Tadao from this universe had died, but..something will change. Because the very same time that Tadao would be picked up by Mori and taken into the Port Mafia, he was there, but it wasn't him.

### Dark Era Arc

A young man with silver hair was spotted walking through an empty alleyway, only filled with a mysterious, blank powder white mist. He arrived at a small bar with a glowing red-and-white sign that read 'Bar Lupin'. Upon entering, nobody was there aside from a calico cat. He ended up drinking some cherry wine, the usual drink he would order. A little while later, he got a sneaking suspicion that he was being watched. Sitting two seats away from him was a young man, close to his age, clothed in black with bandages covering one of his eyes. He didn't address himself at first, remaining an enigma until he stated his name, Osamu Dazai.

It had gotten late enough that they had been talking with one another, they decided to head home. Out of his own curiosity towards the individual he met, Dazai said that Tadao could spend the night with him, the latter reluctantly agreeing with it. They headed back, and Tadao tried to fix up his bandages without the executive knowing, which was rendered useless. Dazai ended up discovering a kitchen knife scar on his lower torso. Upon arguing with him about it, he managed to discover it was indeed self-inflicted, just like he thought it was. With a little persuading, no manipulation, Tadao told Dazai everything he could about his past and what led him to join the Port Mafia.

### Eighteen Arc

On the exact day that Tadao turned eighteen; December 10th. He had returned to the headquarters of the Port Mafia after completing a mission, and had been promoted to the role of executive on that day. After completing so many tough missions thus far, especially under so much pressure, he was deemed more useful than ever to the organization. He was also able to work more frequently with Dazai, as well as another executive before him, Chūya Nakahara. While he had become closer to Dazai as more and more time passed, his distrust grew stronger, as did the other's shadow behind his back.

## Plot

##### Chapter 0

When orphan Ryūnosuke Akutagawa kills a group of six outlaws who killed his friends, he encounters a bandaged man in black who originally planned on recruiting him. However, he sees how the boy is only bent on killing out of blind rage and revenge, a remark that angers Akutagawa. He tries to kill the man, but to no avail, much to his shock.

The man then decides to choose another person to become his right-hand man. With Akutagawa at his limits, the man invites him to a rematch in the future. Until then, he declares that he shall hold on to Akutagawa's younger sister. During this ordeal, the man in black had another man with him, a mysterious figure cloaked in a white blanket of mist. All that was visible of him was a pair of silver eyes in the darkness, and the man in black addressing him as 'fox'.

##### Chapter 1

Four and a half years later is when Akutagawa joined the Armed Detective Agency, under the guise of detective Sakunosuke Oda. Simultaneously, a squad of mercenaries face Atsushi Nakajima, feared as the Port Mafia's White Reaper, and the notorious Kyōka Izumi, leading them to complete their mission on orders of Mafia boss Osamu Dazai. When Dazai had stated his plan for phase three, his next target being the agency directly, one of the first to receive these news was the silver-haired male whom he addressed by the nickname of 'fox'. Upon receiving this information, he leaves the office to collect intel.

##### Chapter 2

Not long after the skirmish between Akutagawa and Atsushi in Café Uzumaki, the mafia's headquarters was stormed by the detective and various armed guards, including some of the subordinates of the Grey Fox on the front lines, had been killed. Watching from the shadows, the silver-haired male approached Akutagawa, revealing himself to be Tadao, one of the executives of the Port Mafia. Initially, Akutagawa questioned where his sister was, and Tadao couldn't answer, so he gave the vague response of not knowing where she was. Not believing him, Akutagawa used his ability to try and subdue him, yet a mysterious white fog prevented him from seeing his target, leading to Tadao's escape. After finding out of his disappearance, Akutagawa left to fight against Atsushi and Kyōka.

##### Chapter 3

Upon discussing urgent matters with another executive, Chūya, Tadao had heard the dangers of Dazai's plan in which the following phase would include his death. He headed for the rooftop where Atsushi had clashed with Akutagawa, having been tracking the White Reaper's location simply for his friend's safety. Dazai arrived before Tadao could, fired Atsushi, and then asked him to live in the outside world with Kyōka. Dazai then passed on information to them of a certain Book that allows whatever written in it to become reality and is home to infinite worlds, including their current world. He ultimately reveals that he had planned for them to face and understand each other. As part of his fifth and final stage, Dazai steps off the ledge and commits suicide, right as Tadao had arrived at the roof to witness his death.

##### Chapter 4

After Atsushi disappeared from the Port Mafia, Tadao was intially left alone with Chūya, and the mafia without a leader. However, Chūya had ended up going on a destructive rampage after Dazai's death, and it took multiple anti-gifted squads to stop him, he was so hurt by being abandoned once again, captured by the government. Upon looking for him, Tadao never found him and was left worried for weeks, until he finally discovered his whereabouts. Requesting to visit him was the difficult part, since he had to complete a crap ton of paperwork beforehand. Once he got to the facility, he was met with a detained Chūya, now the leader of the Port Mafia as Dazai's former right hand. Now, of course, he had to get used to seeing his former friend in a different light, now that Chūya had to lead the mafia in Dazai's place.
