All That Led Us Here (Part 1) Yandere!Overhaul x Fem!Reader

Part 2

Summary: Orphaned at the tender age of six, you are taken in and raised by The Head of The Shie Hassaikai along with his young son, Kai, who takes a strange and immediate interest in you, to an obsessive degree... one that only seems to grow as the years go by. A life with him and The Yakuza is all you've ever known, but is it all you really want? Kai would certainly have you believe so, and he’ll do whatever it takes to make sure you never question it.

Warnings: None for this chapter, in fact, the first few will be relatively tame as we build up to the darker chapters later on, but I will make note of them as they pop up per chapter.

Side Note’s: Just a few quick things to help give you an idea as to how this AU’s world is set up. So first off, there are no quirks in this world, so that means that the Yakuza clans are still strong, wealthy and a huge influence in the Japanese underworld, unlike in the cannon version, and the Shie Hassaikai are one of the biggest if not THE biggest. Second, Kai is The Big Bosses biological son and not just some street rat that he took in. Since we never actually learn the old guys name, I figure that it can easily be played around with to suit the needs of this story and Kai’s looks can be explained by saying that he takes after his deceased mom. And finally, Eri will NOT be making an appearance in this story as of yet.

And as always, I want to give a BIG thank you to my amazing friend @talpup for all the brainstorming and encouragement on these stories! I’m sure I would have given up on this blog a while ago if it wasn't for all of their help. I highly encourage anyone who takes the time to read this to go over to their page or their AO3 account under the same name and check out their works, especially Chaos and Erase The Shadow. They are two of my favorite BNHA fics of ALL TIME!

Kai could still remember the first day he met you, no matter how much time passed or how many years flew by, that day was always going to be crystal clear in his mind.

It was the middle of a sweltering hot summer and his father, the head of the notorious Yakuza clan, The Shie Hassaikai, had received a call from an old friend asking him to come visit him on his deathbed in a nearby town. His father had immediately left, but returned just a few days later.

Only, he wasn’t alone when he came back…

It was already early evening when Kai, who was ten at that point, heard the commotion coming from downstairs and had gone outside with all the others to greet his father when he arrived home and was just as shocked, though he hid it very well, as everyone else to see that he had a little girl no older than six with him.

A tiny little thing wearing a purple sundress and hiding behind his father’s legs while she trembled like a leaf. She was so small that, if it weren’t for the quiet little whimpers coming from her, she may have gone completely unnoticed and Kai couldn’t help but idly wonder who she was and what she was doing with his father.

“Kai?” His father had called out to him once he was spotted by the gate. “Come over here Son, there’s someone you need to meet.”

Kai, being the well behaved and dutiful son that he was, immediately went to his father. He couldn’t deny that he was curious as to who the little girl was and even a stoic child like him was still prone to childlike tendencies every now and then.

“What is it Pops?” He asked, his voice already showing signs of deepening despite his young age. And since he had recently hit a growth spurt, he was easily a good foot or so taller than the little girl currently clinging to his father’s hakama.

His father stepped aside to reveal the child to him in full as he gazed down at her with a look of of care and pity. “Kai, this is (Y/N), she’s the daughter of a dear old friend of mine who recently passed away and she’s going to be living with us from now on.” His father reached down to pat you on the head and Kai knew from experience just how comforting that hand could be in a stressful situation, though he’d likely choke on those words if he ever tried to admit them out loud. “She’s family now, so I want you to look out for her. Ya hear me boy?”

Kai had nodded in agreement without a moment's hesitation, he was always eager to please his father no matter what the task was, though, to be honest, Kai had no real experience dealing with kids his own age, let alone one so much younger than himself. He tended to avoid the idiots at his school, they were always running around, getting filthy and he wanted no part in that, and it’s not like there were any other kids that lived in the compound for him to interact with. Hell, there hadn’t even been a woman living there since his mother died nearly eight years prior.

Kai snapped himself out of his own thoughts when he heard his father speak again, seems he wasn’t done talking just yet.

Kai watched as his father gave you another pat on the head as this time, he addressed you directly, his voice much softer and kinder than Kai could ever remember it being. Perhaps it was because you were a girl, or maybe it was because he felt sorry for the situation you were in, your father had just died after all. Either way, this was a side to his old man that he only ever saw when he talked about his late wife, so this was a rather surreal experience for the young boy.

“(Y/N), this brat here is my son, Kai.” He said, motioning his head towards the golden eyed boy. “If you need anything at all and you can’t find me, I want you to go straight to him, alright? This is going to be your home from now on and that means that you can just think of him as your big brother if that makes it easier.”

You had been looking at the ground for the majority of the time, but when you briefly glanced up to meet his gaze, Kai couldn’t help but feel drawn to the big (e/c) eyes that seemed to take up the majority of your chubby little face. They were wide and full of fear, but also a great deal of curiosity as you took in your new surroundings.

You gave him a small, barely there nod of your head as you mumble out a quick response, your voice just as tiny as you were in stature. “N-Nice to m-meet you Kai-san. I’ll try n-not to be a b-bother for you.” And then your eyes are back on the ground and Kai is left with a strange feeling in the pit of his stomach as he uncharacteristically thinks that he wants you to look at him again, and for longer this time.

The old boss tries to muster up a weak smile in the hopes that it will put you at ease. “I’m sure the two of you will get along just fine once you get used to each other. Now, why don’t we go have some dinner and then get you off to bed? It’s been a long few days and I’m sure you’ll feel a bit better in the morning.”

With affirmative nods from both children, nothing more is said as everyone is urged to get back to their usual duties despite talk over who the unexpected new addition to the household is and where she came from.

—————

Later on that night, after a quiet dinner was shared amongst the three, Kai went off back to his room and quietly continued to work on his summer homework. Pops was insistent that he keep up his grades, inciting that just because he was set to inherit the role as head of a mob family, that didn’t mean that he was allowed to be an ignorant fool with no brains to back himself up, and Kai was inclined to agree, there was only one thing he hated more than filth and that was stupidity and a general lack of common sense.

Tonight however, this usually easy task was proving to be just a tad bit harder to stay focused on.

The main reason?

He can hear your soft cries from down the hall in your new room and it’s proving to be rather distracting. Not that you were being overly loud, but thin walls and shoji screen doors don’t provide much in the way of soundproofing or insulation. And with the two of you bring the only ones living on this floor, his old man's room being situated one floor above and everyone else further down, it was even more quiet than a normal house.

Without really stopping to think about what he was doing, Kai got up from his desk and left his room to wander down the hall until he found himself quietly standing outside your door. He debated with himself for about thirty seconds before he made the abrupt decision to just open the door uninvited.

There you were, curled up on an unfamiliar bed that was definitely way too big for someone so tiny, your shoulders shaking even as your head shot up at the sudden sound of sliding wood and big fat crocodile tears continued to roll silently down your cheeks.

“U-Um… w-what are-”

“You’ve been crying.” Kai interrupted you.

You looked down, he really wished you’d stop doing that, almost as if you were ashamed to have it pointed out so bluntly.

“I’m so-sorry, I w-won’t do it a-again, I pro-promise.” You managed to get out between more sniffles.

Kai normally hated the sound of crying, it was like nails on a chalkboard to him and he attributed it to weakness, yet another thing that he so deeply detested. But, he supposed that given the events you had likely been subjected to over the course of the last few days, your blatant display of emotion was understandable, if not outright expected of you.

And besides, he thought, he knew what it was like to lose a parent, but he still had his old man at least, that was more than could be said for you, you didn’t have anyone.

No one but him and Pops…

Kai wouldn’t be able to properly articulate to himself what it really was, not until he was older and understood himself a bit better, but he felt an odd sensation swell up in his chest at the thought of you relying on him, of you needing him, he liked the idea of you staring up at him with those big watery eyes and asking him for help, begging him to make the hurt go away.

But more than that, he wanted to be the reason you smiled. He had yet to see a smile grace your face, but he knew that he wanted to be it’s cause when it did finally happen, or at the very least, he wanted to be the first one to see it.

It was a strange feeling, and not one he was at all used to, but Kai was a pragmatic child and rarely ever second guessed himself once his mind had settled on an idea. His father often told him that if he continued to cultivate that trait, it would make him an even better boss than him someday.

And to that end, he did what his father would expect of him…

“Do you… want me to stay with you, until you fall asleep?”

The two of you stared at each other for roughly a minute before you mutely nodded your head and Kai silently made his way over to your bed, easily climbing onto the tall mattress and sitting upright against the headboard while you laid your head back down on the pillow.

Kai never took his eyes off your face.

“Thank you Kai.” You mumbled sleepily, your swollen, puffy eyes already drooping as sleep threatened to finally claim you.

He wasn’t really great at comforting others, not that he had ever tried, so he acted on pure instinct, reaching out and taking your tiny hand in his own and closing his fist around it, an act that both shocked and astounded him, though he never let go of your hand regardless of that.

It had been so long since he had touched anyone else that he’d almost forgotten what another person’s skin could feel like and despite his steadily growing aversion to physical contact, he didn’t feel even the slightest bit of disgust when he felt your skin against his own. In fact, it was no different than if he was reaching up to touch the flesh of his own face.

Kai knew that this had to mean something, he just didn’t know what that something was just yet.

But he could figure it out, he thought, gazing down at your peaceful face as he brushed some of your hair behind your ear. This was your home now, and he had all the time in the world to learn what it was about you that seemed to set you apart from the rest of the filthy world.

—————

About an hour later, Kai was just beginning to feel his own eyes drop as sleep fought to overtake his senses when he heard a shuffling sound by the still open door and, looking up, he wasn’t all that surprised to find his father standing there in the doorway.

The Boss couldn’t sleep and so he decided to wander down and check on his new charge, he was already beating himself up for leaving you alone in a dark, unfamiliar room. He half expected to find you still awake and crying, however, what he found instead was something far more surprising than anything he could have imagined on his own.

You weren’t crying, in fact, you were sound asleep. Sound asleep and holding his sons hand, his son who hated all unnecessary physical contact. To say he was surprised was an understatement, he never would have expected to find a scene like this, not in a million years.

Kai meanwhile, couldn’t help but feel the slightest bit annoyed that his time alone with you was being interrupted. How was he supposed to think and ponder these new developments if he was being distracted by his father’s eyes boring holes into him.

But, he supposed this could have it’s own benefits, now that they were alone, he could ask his father some questions that have been plaguing his mind since he first arrived home.

“Why is she here Pops?” He asked quietly, never taking his eyes off your sleeping face.

The Boss was not the kind of man that believed in treating his son with kid gloves, he told him how things were in a very direct manner and rarely ever beat around the bush when talking to him. He was going to be taking over one of the most powerful Yakuza clans in the country and he couldn’t afford to have his only son and heir be a spineless weakling. Some might call him cruel for laying so much on a young child’s shoulders, but he knew just how fast he could be swallowed whole if he didn’t possess the necessary moral fiber to stand on his own two feet in this dangerous world he was set to rule in. It might not seem like it, but he loved his son and wanted to see him succeed and push the clan further then even he had.

“Her father was an old friend of mine from back in the day.” He began and leaned one of his large, broad shoulders against the door-frame. “He wasn’t a criminal, in fact, he was a pretty average guy. But he helped me out of more tight spots in our youth then I care to remember and despite knowing about my Yakuza heritage, he never dwelled on it or judged me for it.”

Kai watched as a look of sorrow passed across his father’s face, something that only ever happened when he thought about his mother and he realized it must have meant that he really cared about this dead man, whoever he was.

“We lost touch over the years, but when I got that call from him, asking me to come see him on his deathbed, I knew I owed it to him to go and send him off.” He took a deep breath before continuing. “When I got there, I found out what it was he wanted from me. His last wish was that his only child, his daughter, be raised by someone he knew and trusted. Neither he, nor his deceased wife had any known living family that could take her in. So it was either I take custody of the girl, or she gets put in the system. Clearly you can see what my decision was.”

Kai suspected that there was more to the story than that, but he got what he wanted so he didn’t press for anymore then that.

“So, you want to tell me what you’re doing here in the middle of the night?” His father questioned him.

Kai still had yet to look away from you and to be honest, he really didn’t want to. “She was crying.”

“So you came in here to check on her?”

“Something like that.” Kai murmured, his usual monotone still firmly in place. “She’s different than the others, she’s clean and I don’t feel sick being near her. I can even touch her.”

It was nearly pitch black in the room but there was just enough light streaming in from the hallway that allowed him to see his sons face, and what he saw there nearly had him busting out laughing, but he refrained for fear of ruining whatever it was that was happening to the boy.

Kai was blushing.

It was small and faint, but the tops of his cheeks were definitely looking a bit darker than usual.

And this seemingly innocuous turn of events sparked an idea in his mind, one that he would need to put some serious thought into, he couldn’t just rush something like this without analyzing it from all angles, but it was an option that could ultimately lead to his child’s, no, his children’s future happiness.

“So I take it you’re not going to be having a problem with her being here?”

Kai looked down at you, at the steady rise and fall of your chest and the way you curled in on yourself. He took in the way you nuzzled your face just a bit closer to him and he found comfort in your soft little breaths that he could feel against him arm.

So, did he have a problem with you?

“I’ll take care of her.”

I hope you all enjoyed this! Please let me know what you thought if you have the time!
