Tadao Yumeno/Synopsis

## History

### Fifteen Arc

The life of a victim, of prey to predator. Yumeno. Such a cursed last name to behold when it belongs to another child, harboring a gift that only a harbinger of danger could possess. Mind control, of all things. It just had to leak into his own power, conjuring hallucinations into a cold mist.

As he grew up, not knowing who his parents were, having scattered memories of it all. He was only left with scattered memories of a younger sibling, who had currently been in a hospital as only a young child. And of course they just *had* to get picked up by the mafia, god knows what happened to them after that. Tadao's life didn't truly begin until one fateful night. He was fourteen and a half, pondering the loss of his sibling that occurred years in the past. Pacing around in his room alone was all he could do, reminiscing over his scars, wondering when his sibling would return, or if they ever would.

Smoke. Flames. Fire. Screaming. Leading him to a shattered window, broken from heat, he escaped the orphanage, leaving his only other friend behind. The white tiger. *The weretiger*. Soon to be sought out by a criminal organization.

Managing to make it to a train station, he ended up by the Tsurumi riverbank, collapsing, near fainting from lack of food, not to mention water. A man clad in black with a red scarf, by chance passed by. Of course, it had to be Ōgai Mori. Taking pity on the young teen who was clearly in a state of insanity, not knowing how to break away from such a past that pained him. He offered him a place within one of Yokohama's most pivital organizations; the Port Mafia.

He knew what he was getting into. He knew he'd turn to a life of crime eventually, due to his cold aptitude and sardonic, antisocial nature. It was in his blood. Besides, his survival was at stake and he was offered a home. He accepted, returning to the Port Mafia's headquarters with his newfound boss.

Tadao was essentially brought back to the headquarters of the mafia, and then, Mori's office. When he was there, he was introduced to two of the Port Mafia's executives, Ace, and Kōyō Ozaki. Having already been serving as a mentor towards Chūya Nakahara, Kōyō initially wished to not take another child on her hands, much as taking a liking to Tadao's dark nature. Mori assigned him under Ace instead, to the latter's dismay. However, as Tadao was trained to fight and utilize his ability by Ace, the two grew close quickly, developing an almost sibling-like bond with each other. Ace normally put special chokers onto his subordinates that connected to his ability, if and when he needed to kill them, however Tadao did not receive one, since Ace saw enough potential in him from the start.

### King of Assassins Incident

This occurrence was a few months before one event that'd change his life. Forever. Having been tipped anonymously, whether it was Ace or Kōyō or the other executives. Tadao had been remotely anxious, suffering to sleep at night, not knowing what to do with himself. He was just a young teenager, tossed into a criminal life. So Mori came up with a plan, to make him feel more at home. The Flags.

A prestigious group of mafiosi, aged 25 and below. He was invited into the group under the guise of the boss, to make him belong, to soothe his nerves. Almost instantly did he become friends with the five, and then another, Chūya Nakahara. Initially they had a rocky upbringing, with Chūya seeing him as too nervous, too afraid to get things done. However, they grew to respect one another through coordinated assignments and hangouts with the rest of them.

Piano Man was the one Tadao looked up to the most. Seeing him as an elder brother and caretaker, as well as a mentor. Piano Man taught him to handle knives, further improving his weapon skillset. He had a pastime at the orphanage of twirling and spinning knives, yet it was drastically helped thanks to the Flags' leader.

Having suffered lack of sleep one night, too overwhelmed to meet with the group, needing time to recharge. Chūya was with the others, only to get kidnapped by detective Adam Frankenstein, to the Flags' amusement. They were told to get a visit from Mori, it was an ambush from Verlaine laying in wait. All of them were massacred...

Except for Tadao. The sole survivor.

He returned to the bar late that night to witness the corpses of his friends. It drove him mad. He went into a state of anguish where his fog expunded, out of control. Unstoppable, his body temperature dropping to a low 50°. Enough to make tears freeze, his eyelashes white with frost.

Once he awoke at home, he discovered a note from Chūya; telling him he was going to put an end to Verlaine. He decided to do nothing. Chūya was more powerful.

### Dragon's Head Conflict

Then the next few months; the Dragon's Head Conflict. A bloodbath, a tragedy. Tadao would roam the city on occasion whenever he had the chance to, thrown into the fray. Cornered by mercenaries from the GSS, enemy mafiosi lurking in back alleys, violent people hellbent on self-defense. He was ordered to take no prisoners and to kill anybody who came across him, much as it was a harsh choice for a fifteen-year old child.

A recon mission, to seek out information from Tatsuhiko Shibusawa's makeshift group of criminals. He arrived at one of their secluded warehouses, only to be clubbed over the head when his guard was down. He was captured before he could even infiltrate the organization, after a mass-scale explosion. Dazai was one of the mafiosi who was captured, yet Tadao was not held with the remaining five. He managed to kill the criminals who attacked him. After the conflict had ended, Tadao was taken to a hospital, having sustained a few wounds and lacerations from the war. Once he was almost fully recovered, Ace drove to the hospital and took him back to the mafia's headquarters. Mori allowed him to rest for as long as he needed to, and he did exactly that, yet it took him several months for the nightmares and flashbacks to fade.

### Dark Era Arc

A young man with silver hair was seen walking through an empty alleyway, only filled with a blank powder white mist. He arrived at a bar with a glowing red-and-white sign that read 'Bar Lupin'. A little while later indoors, 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. Soon after, he introduced the silver-haired male to his friends, Sakunosuke Oda and Ango Sakaguchi.

The next time he was seen was at the Freedom Restaurant, sitting alone by the window with only a burner phone he used to communicate with Mori. Upon getting attacked by Mimic soldiers, Tadao instantly retreated before he could get jumped. Oda arrived not much later when the restaurant owner was already killed, which soon led to the van explosion and the orphans' deaths. Tadao had been hiding behind the building for a majority of that time, and he got subtly injured during the explosion. After a group of mafiosi went to investigate, he returned to Dazai's apartment to have his wounds treated. While they were there, Dazai found even more burn scars from the fire and other injuries on Tadao's arms, having strictly instructed him to never let anyone hurt him again, since he was a valuable asset.

Only hints of his appearance being the mist in the alleyways, revealed to be from his ability. Once Dazai arrived at the manor following Oda's demise, he was immediately met with his last words, to leave the mafia and become a good person. Tadao received intel from Akutagawa that Dazai supposedly aborted a mission and disappeared, without saying goodbye. This left a major impact on his mental health, yet he didn't heavily resent Dazai for leaving like he resented Ango for betraying them.

Alone in his own apartment with his bandages tightly around his skin, as if never wanting to show those scars when only his 'best friend' had seen them. He gradually started to dissociate from his friendship with the former executive, developing amnesia as a result of his trauma.

They are no more than strangers. He forgot bits and splices until nothing was there. A faded mirage of that week from his teenage years.

### 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 he was alerted by Ace to go to Mori's office immediately. Once he arrived there, Mori proceeded to congratulate him on all the tough missions he completed thus far, especially under so much pressure. Tadao took the compliments with a deadpan expression, asking the mafia leader why he was summoned, since it wasn't logical to be called up just for a bunch of empty words.

Ace and Kōyō then came in, and Mori announced that Tadao was to become the Port Mafia's newest executive. After the death of the Colonel during the Dragon's Head Conflict and the absence of Osamu Dazai, the mafia only had three executives, Ace, Kōyō and then Chuuya. Subtly suspicious that his rise in rank was caused by Dazai's fallout, he was meant to be a replacement for the 'Demon Prodigy', yet a lie was called. Mori fully intended to leave an executive spot open for Dazai, in the event he should return to the Port Mafia one day.
