Tadao Yumeno/Relationships

* Port Mafia
* Armed Detective Agency
* Special Division for Unusual Powers

## Port Mafia

### Paul Verlaine

*'' You took them away from me..how does it feel that I'm the only one left? If you want to kill me, do it. "* —Tadao argues with Verlaine

Verlaine and Tadao have a rather tense relationship with one another. With Tadao being the last remaining member of the Flags, and Verlaine having killed the rest of them because of Chūya, he hates Verlaine with a seething passion. If it was up to him, he would let Verlaine kill him so he could join his friends, but he knows that if he does that, the mafia will down an executive. He always puts the mafia first, regardless of how guilty he feels for letting the Flags die without him.

During the event of their murder, Tadao was roaming the city, having not met up with them at their usual gathering spot. To this day, Tadao knows Verlaine is still alive and kept in one of the mafia's underground strongholds, training assassins. He still carries his grudge and disdain for his 'fellow executive', yet deep down, he's terrified of him. His lingering fear is that one day, Verlaine will try to finish what he started with the Flags so long ago, if he ever found out Tadao was still alive and in the mafia now.

### Ōgai Mori

*'' Anyone who dares cross us will feel their blood run cold. You can trust that I won't hesitate to kill anyone who tries to harm the Port Mafia. "* —Tadao joins the mafia at nearly age fifteen

Tadao has a very limited circle of who he can trust. Mori hangs in the balance in that regard. He was the reason that he joined the mafia at such a young age. When the orphanage burned down and he ran away, leaving nowhere else to run to, the mafia leader showed up by chance and took him under his wing. He remained as such until Ace was assigned as his caretaker.

He doesn't care how much his ability hurts him, so long as he can get the job done, that's what Ace taught him. In a similar fashion to Chūya, Tadao always holds his mission or assignment as his first priority. He doesn't solely trust Mori, yet that is purely because of how he was raised and the life he lived. After all, he has severe trust issues. He holds him in high respect, either way. Mori gifted Tadao with a black trench coat, similar to the one he gave Dazai, although it was a completely different one. He rarely wears it, but when he does, he has it over his shoulders in a fashion that the other mafiosi wear them.

### Kyūsaku Yumeno

*'' I haven't seen them in years. I don't even know if they're alright, or where they are. "* —Tadao reminisces about their past together

Q and Tadao were very close as siblings when they were younger, too young for Tadao to remember. They would scarcely argue, and most of the time were closely linked, having similar ideas and opinions about things. A few things they used to do would be to craft flower crowns, sew homemade dolls, play games, and more. They had a close bond with one another that wasn't broken until one day. Q had been taken away to a mental hospital. Not ever knowing what happened to them, Tadao had grown up alone in the orphanage with only scattered memories of Q and their presence and the impact the child left on his life. He can't remember much about that part of his past, although he can never forget Q.

A few months later is when the orphanage caught fire, and he was forced to run away and join the Port Mafia. By then, Q had been imprisoned because of their disastrous ability, after joining the mafia's ranks at the young age of six. To this day, Tadao has no idea where his younger sibling's whereabouts are, whether or not they're alright, or if they still remember their time together. He keeps a small doll that looks similar to the one connected to Q's power, keeping it hidden away in his flat so nobody knows about it. He never tells anyone in the Port Mafia that Q is his sibling, for fear of backlash due to the chaos that Q caused. He doesn't want to be seen as his sibling, and he refrains from his secret getting spilled. A notable trait that he has that has a resemblance to Q is a powder white undertone of hair below his silver locks, that is only visible if he moves it. It's a hidden undertone that is vaguely similar to Q's two-toned shades.

### Kōyō Ozaki

*" A dark flower. I never knew what that meant, but the longer I spent with her I realized it. If I'm meant to be in the darkness forever, I'm willing to do so. "* —Tadao reflects on his inner nature

Kōyō and Tadao have a pretty good relationship in the Port Mafia, and the red-haired woman might just be one of the people he trusts the most. When he was first brought into the mafia's headquarters, the night he ran away, Kōyō was introduced to him along with Ace. She noticed how as small as Tadao seemed, he wasn't to be underestimated. As his training continued on with Ace, he would occasionally receive lessons from Kōyō as well. He learned how to enhance his knife skills with her aid. He already had a subtle ability to use knives, from when he would sneak into the orphanage kitchen at night and practice throwing and spinning knives; it was just a pastime of his that eventually became useful in the mafia's world. She was able to help Tadao become more efficient with that skill, to the point where it helps him greatly during fights.

She also acted like a parental figure towards him, somewhat. Kōyō reminded Tadao of what he imagined an elder sister to be like. It was important for him to have that kind of relationship since he had little people to talk to as he was growing up, didn't have anyone to call family in particular other than Atsushi and Q. To him, the mafia felt more like his family than anybody ever had. He was on her side when she tried to bring Kyōka back into the mafia, because he was able to realize how Kōyō viewed her as a flower of darkness, just like he heard her say about him in turn.

### Ace

*" He honestly terrified me when I first saw him. But I grew to respect him...regardless if he died because of his own will. " —*Tadao speculates on Ace's death

Originally, Tadao was afraid of Ace when the latter was first introduced to him along with Kōyō almost immediately as he was brought into the mafia's headquarters when he was barely fifteen. The executive intimidated him not only from looks alone, but the way he carried himself and his supernatural ability. However, the more he trained under Ace, he gradually grew to somewhat respect him. However, there was hardly any trust in their relationship at all. Tadao was subtly aware of Ace's lack of loyalty towards the Port Mafia, he just never pointed it out before. He was never that good at reading other's emotions unless he knew them well, and with every training session and fight, he was able to pick up signs of Ace's true personality.

The executive would occasionally address Tadao as a 'sharp diamond', since he had a silverish hair color. Not only that, but he was not to be underestimated with his training. His ability to stealthily move through darkness and his calm, emotionless demeanor made him seem somewhat inhuman, without feelings. While Tadao saw Ace as an elder brother in the littlest ways, he still didn't trust him as much as he trusted Kōyō. When Ace died due to Fyodor Dostoevsky's trickery after the destruction of the Moby Dick, he didn't know that Ace was fooled and he naturally thought that he committed suicide because of his disloyalty towards the mafia. In Tadao's eyes, his former mentor was too cowardly to continue working for the mafia any longer, and he felt a shred of remorse for his passing, nothing more.

### Ryūnosuke Akutagawa

*" So what do we have planned now? I'm sure that with your power, you'll slaughter, I'll cover it up. "* —Tadao meeting up with Akutagawa for a mission

Tadao and Akutagawa are somewhat close friends. They get paired on missions a lot, usually when commanding the Black Lizard. They were both able to come to an understanding; they share the fact that they are orphans, even if their backstories are completely different. Regardless if Akutagawa knows that Tadao once had history with Atsushi, that doesn't stop him from working with the executive on a regular basis, whether or not he's forced or encouraged to do so. While he and Higuchi work together, sometimes Tadao works with them to deliver commands or go on separate missions. On their days off, sometimes he joins Akutagawa and his younger sister to go out into the city, whether it be shopping or visiting parks, just regular things that they end up doing outside of work.

Nobody should underestimate them as a pair. If they are in battle, they can be fairly deadly. With Akutagawa's ability and Tadao's complementing one another well, they can brutally assassinate anyone who stands in their path. A strategy they commonly use is where Tadao uses his fog ability to create a smokescreen, so Akutagawa can relentlessly attack from a vantage point where nobody can see his ability coming towards them. Closely linked in missions and outside of the mafia's work, they sometimes have a friendly banter here and there.

### Gin Akutagawa

*" I don't call you my partner in crime for nothing. "* —Tadao and Gin team up for a mission they were assigned

Tadao's friendship with Gin is just as closely linked as her brother's. Having similar assassination skills and a shared history with Verlaine, they have a very closely knit bond between them. The executive was introduced to Akutagawa four years ago, having learned about his skills and powerful ability widely spread through the Port Mafia at such a young age. Soon after they became able to trust one another, Akutagawa had Gin meet Tadao as well. She would often try to go on assassination missions with him whenever she could, since he somewhat looked up to her and would receive her guidance occasionally.

Gin being able to move around silently and Tadao's power to conceal his appearance meshed fairly well with one another, even if Gin did not possess a supernatural ability. Gin also taught Tadao some of her tricks that she knew, as well as how to better handle a weapon. Whenever they have days off, Gin and Tadao can be seen in jewelry stores picking out items for one another. Tadao also had a pretty good laugh when Higuchi first found out that Gin was, in fact, a girl.

### Sakunosuke Oda

*" Why is this curry so damn hot.? " —*Tadao tries some of Oda's regularly ordered spicy curry

The two of them met naturally because of Dazai introducing Tadao to Oda four years ago, considering the latter's somewhat antisocial and distrusting nature, even though he was only seventeen years old at that time. After hearing so much about someone named 'Odasaku' from the young executive, he figured it wouldn't hurt to try. When Tadao first met Oda, he initially got a parental vibe from him without seeming to know that he took care of the five orphans. He would meet the two of them at Bar Lupin whenever possible, and Ango would be there too, on occasion. It was thanks to Dazai that Tadao even knew the other two to begin with.

Having already told Dazai that he was an orphan, it was only natural that Oda knew about it as well. Tadao looked up to him, regardless if he didn't quite understand his methods of refusing to kill, even in the mafia's world filled with darkness and bloodshed and war. He managed to see the other as a father figure, the very first person who managed to make him feel that way especially. He saw Ango in a similar fashion. When Oda was killed in the battle against Mimic's leader, Tadao never discovered it until he allegedly found out from Chūya that Dazai had left the Port Mafia. The first thing Tadao did was visit Oda's grave, having felt guilty that he didn't even get to say goodbye before he went to face the soldiers by himself. Even today, he is still pained by Oda's death, although his subtle amnesia from that time period made him forget exactly why.

### Chūya Nakahara

*" I wasn't trying to freeze anyone today, thanks. " —*Tadao's response to Chūya after the latter asked to spar him

While Chūya and Tadao tend to have a tense relationship at times, their history goes back far enough that they have somewhat shared trauma. Back with the Flags is when the two first met. In the beginning, Chūya saw Tadao as an anxious person who most likely didn't have much ability when it would come to fighting. However after knowing more about his past and what he went through, along with his status on missions, he grew to respect him. Tadao also has a high respect for Chūya in turn, having spent roughly six years around him in the mafia alone. Chūya became an executive before he did, yet he was promoted at eighteen himself, so he never got used to receiving orders from Chūya at all. As equal ranks, they both work together frequently. One wouldn't exactly call them best friends, but they do know one another very well. The other's dislikes, personality, mannerisms, and backstory. They also share an equal disdain for Verlaine since he assassinated the Flags six years back. While Tadao felt and still feels guilty to the present day for leaving the Flags alone to die, Chūya never blamed him and never will.

Often they get into arguments or small banters that don't affect their relationship whatsoever. They occasionally tease each other with nicknames. It can normally happen during a mission or a fight, where one of them tosses out insults to the other, simultaneously rushing into battle. They have fought back-to-back before, and Tadao can trust Chūya to a great extent compared to others. When he trusts someone, he doesn't take it lightly at all, after having a hard time putting up such a cold and emotionless front. He rarely lets others see through that, however, Chūya is one of them. Tadao lets Chūya understand his true emotions and feelings, but Chūya can predict what Tadao would end up doing in a situation. Not only that, but he can see through his lies and deceits whenever he has something to hide. The only thing Chūya doesn't know about Tadao is his relation to Q, which he keeps hidden more than anything else. Tadao vaguely knows of Chūya's hatred for the child, and he knows that if he let out that secret, bad things would happen. The event that Chūya discovered it; when he found a small replica of Q's doll that Tadao made himself.

### Albatross

" *No...no, this isn't real. I'm seeing things again, you wouldn't go down this easy. " —*Tadao's reaction to finding the Flags' corpses and seeing Albatross among them

### Piano Man

*" Alright, so I twist it like this, right? " —*Tadao getting taught to handle a knife by Piano Man

### Lippmann

*" You were an actor.? Think you can teach me something? " —*Tadao learns about Lippmann's profession

### Iceman

*" I kind of wonder how many people you've assassinated..just curious, really. " —*Tadao asks Iceman about his kill count

### Doc

*" No, I didn't get hurt. I'm fine. The target is the only one who came out scathed. " —*Tadao reassures Doc after he completes a dangerous mission

## Armed Detective Agency

### Atsushi Nakajima

*" Little tiger...I'll miss you. " —*The last words Tadao ever said in regards to his friendship with Atsushi

Only back in the orphanage was when Tadao still considered Atsushi a close friend. They met in one of the dark halls when Atsushi was barely twelve years old, Tadao in turn being fourteen. It was a little while after Q's disappearance. Tadao was fairly lonely until he met the other boy, and they became close friends. Atsushi was originally distrusting and scared of Tadao since the other kids didn't treat him well at all, yet he learned soon enough that he didn't wish to hurt him at all, and even found his ability to be fascinating. They would both compare abilities quite often; sometimes they would lock themselves in a large room and Tadao would use his mist ability to create a wonderland for them to run around in.

He called Atsushi 'little tiger', and in turn, he gave him the nickname 'Tao Tao', purely for the way his name was spelled. They would hang out whenever they had the chance to, and they were closely bonded with one another until the day the orphanage caught fire. Atsushi was worried that Tadao didn't make it out alive, when in reality, he ran away from the burning cinders and ended up joining the Port Mafia. In the present time, Tadao never took part in the missions to capture Atsushi when he still had the bounty on his head. He knew of his past with the weretiger, and wanted nothing to do with anything that may harm him. He feels an underlying guilt for leaving him behind, even now when they're part of rival organizations.

### Kyōka Izumi

*" If Kōyō wishes for her to come back..I'll help. If she's a flower of darkness like me, then it makes sense for her to belong here..right.? " —*Tadao's inner monologue when Kōyō tried to bring Kyōka back into the Port Mafia

Tadao didn't know Kyōka that well within the mafia, since he didn't work with her that often and rarely ever spoke with her due to her emotionless persona and doll-like attitude. The only reason he knew her was because of Kōyō's likeness to her, and he respected her abilities as an assassin even though she was only fourteen years old. He understood that killing thirty-five people in only a few months was not an easy task at all. When Kōyō made it her goal to bring Kyōka back to the Port Mafia, Tadao was willing to help her. He even used his ability to conjure a smokescreen when he was attacked by Demon Snow out of retaliation.

In the present day, Tadao is the least bit relieved that Kyōka is at least happy at the Armed Detective Agency instead of how she was within the mafia. He was also a little thankful that he wouldn't have Demon Snow behind his back anymore. On rare occasions where he saw her again, he was always surprised that she displayed so much more emotion than she used to, and in a way, he was envious that she could do it, yet he remained proud of her nonetheless.

### Ranpo Edogawa

*" Getting trapped in that book was a damn nightmare. Whoever the hell his accomplice is..they did this. " —*Tadao's observation of Ranpo's collaboration with Edgar Allan Poe when the latter was trapped in a book with Chūya

During the events of the Cannibalism, Tadao was one of the envoys on the front lines to protect Mori from the agency's assault plans. He had a portion of the Black Lizard assisting him, all armed with sub-machine guns as well. His battalion was in close range to Chūya's group, since they were protecting the headquarters from the entrance on both sides. Ranpo showed up after Chūya received a tip that the agency members charged right through the front door, about to protect the Port Mafia leader himself when he saw the detective approaching instead. After receiving brief insults from Ranpo regarding his defeat against his old partner, Chūya activated his gravity manipulation, charging towards the detective from the air. Having heard his screaming, Tadao rushed over to the scene, only to see Chūya's fist trapped in Poe's novel. He quickly ran over to try and help him, getting trapped in the novel himself after not being fast enough to run away. He assisted Chūya to help the two of them escape, while Ranpo naturally solved the mysteries on his own.

### Osamu Dazai

*" The Demon Prodigy. We were friends, I remember that..but..who even was the Demon Prodigy in the first place.? " —*Tadao's amnesia recollection after he hears a familiar name from his past

The relationship that Dazai and Tadao have is far more complex than most, nearly as much as his in-depth bond with Chūya. The two of them met during the Dark Era, specifically one night in Bar Lupin. Tadao was in the bar alone with a glass of cherry red wine, seemingly bored and uninterested in anything, his trench coat covering up his body and his grey eyes closed. Dazai was secretly watching him for a while, until he opened his eyes and found the executive staring at him. The two ended up talking, surprisingly through Tadao's antisocial nature. Eventually they both went home after it had gotten late, and Dazai discovered that Tadao's torso was bandaged.

Underneath the bandages was a self-harm scar from a kitchen knife that he inflicted upon himself three years ago in the orphanage. Dazai was a little annoyed that Tadao hadn't told him about the injury beforehand, but then again, he didn't fully trust him yet. That night is when Dazai found out more about his past and the life he used to live before joining the Port Mafia, and in tandem, accidentally removing the bandages covering his eye. Tadao was the very first person to see him with both eyes completely uncovered.

Soon after that encounter, Dazai introduced Tadao to Oda and Ango. The four of them would frequent Bar Lupin together, whenever they had the opportunity to do so. Thanks to Dazai, Tadao grew close with the three of them all at once, finding a few friends to place his trust in. Although that didn't last long, at all. What followed was Ango's betrayal, the orphans' deaths, and soon after, Oda's. Tadao lived through Ango supposedly siding with Mimic, and also dealt with the crushing pain of Oda's death. However, what he didn't know was that soon after, Dazai disappeared from the mafia completely.

He was left not knowing what happened to Dazai whatsoever, and the Port Mafia was down an executive. He never tried to find Dazai, call him, or trace his location since he went underground to get a clean slate. In fact, the next few months after that is when Tadao turned eighteen. On that exact day, he was promoted to executive himself after some speculation from Kōyō and Ace, as well as Mori. He was suspicious that the only reason he became an executive was to replace Dazai, yet with Mori still keeping an open place for him, that wasn't true. After all, he had developed a name for himself in the mafia as the infamous 'grey fox'. His talents were fairly well known, along with his emotionless and cold facade that would leave anyone terrified of him. As the time passed on, Tadao became emotionally detached from the former mafia executive, resulting in his amnesia to soon follow. He slowly forgot, little by little, different details about Dazai until he was practically a stranger to him. All that was left of their friendship was Dazai's nickname, the 'Demon Prodigy'. That was all that Tadao remembered in the end, he just never knew who it really was.

In the present, Tadao still struggles with his amnesia in remembering who Dazai was initially. His dissociation resulted in his memories being scattered, so he largely forgot a portion of his life from the Dark Era on its own. Those several weeks from when he was seventeen are completely lost to memory, and Dazai is no more than a stranger in his eyes. Sure, he's heard of his name and that he's a detective, but he doesn't remember that he used to be in the mafia at all. Although, one day something might trigger his amnesia to fade away so he can reconnect with him again.

## Special Division for Unusual Powers

### Ango Sakaguchi

*" If I wanted to kill you, you would be dead already. " —*Tadao's chilling words to Ango during the events of the Yokohama fog incident

The silver-haired executive's relationship with Ango Sakaguchi goes back to the Dark Era, when they initially first met one another. Dazai had introduced Tadao to not only Ango, but Oda as well, and the four of them frequented Bar Lupin quite often. While Ango's exceedingly calm nature and level-headed demeanor often made him envious, he also looked up to him quite a lot seeing as he remained as relaxed as he was even when he was an informant for the mafia, which could've been a majorly stressful job. Tadao even saw him as a father figure in a few ways, even if they weren't that far apart in age, just like Oda. When Ango disappeared and he heard from Dazai that he had betrayed the Port Mafia, he went into a catatonic state and partial denial. He didn't believe that Ango could've possibly betrayed them, although once he knew the details, he was pretty angry about it.

He would have never imagined Ango of all people to betray them, so he quickly burned all the feelings he felt towards Ango being a father figure towards him, resenting his actions instead. Similarly to Dazai, Tadao dislikes Ango, but doesn't hate him and refuse to speak with him. During the Yokohama fog incident after Chūya made a deal with him, Tadao traveled to the facility for the Special Division for Unusual Powers. He had been in Kyoto for some time after an assignment had taken him there, but he returned to Yokohama despite hearing about the deadly fog that spread throughout the city. He was almost instantly separated from his own ability and was forced to fight a mirror of himself, only receiving a tip from Akutagawa that destroying the red crystal was the key to gaining his powers back. Once he did that, he used his own fog to protect himself. He showed up at the government facility, having known that Chūya accepted a job from Ango. Initially, he asked what it was about, to which Ango told him the honest truth. Tadao was slightly irritated that his fellow executive was put into harm's way, yet he quickly pushed his feelings aside since he knew better than anyone that Chūya would be able to handle the conflict on his own. However, Tadao had promised himself that if he had the chance to kill Ango, he wouldn't do it, since he still remembered the time they were friends back in the Port Mafia.
