The Many Married Lives of Izuku Midoriya

Kai Chisaki (Overhaul)

A/N: Izumi is the daughter of All For One in this and quirkless. Kai and Izumi are also Eri's biological parents and he is a good father. I'm not touching canon with a ten-foot pole in this chapter and you can't make me.

-Most people would get upset at the knowledge that they were going to be apart of an arranged marriage, that their destiny was to be but a pawn upon the board of their families plans to grow in status and power, most people were not Kai Chisaki and Izumi Midoriya, the heir of the Shie Hassaikai and the spare of the Underground having known each other since childhood, with The Boss and All For One often bringing the two of them together in hopes of a bond being formed so that they could permanently secure their alliance, however, no one had expected for the desired bond to have been made the second that the two children had seen each other, or that said children would spend the next several years hiding their relationship from their families, with Kai and Izumi having made plans to elope before they had found out that they were to be sworn to one another, and so, instead of spending a year hiding away in Europe waiting for their families to calm down, the pair were married in a traditional ceremony at the Shie Hassaikai estate; where Izumi was able to walk down the aisle beside her father dressed in a white kimono embroidered with gold flowers the same shade as Kai's eyes.

-Bitch, Pet, Slut, those were just a handful of the names that Izumi had received over the years whenever certain groups of people though that Kai was out of earshot, many of his clients and associates seeing Izumi as nothing but a mistake and stain on the Shie Hassaikai name, Kai had so many better options that he could have chosen for his marriage partner after all, with sons and daughters from practically every other organisation inside of Japan having been paraded in front of Kai ever since he had turned 16, when The Boss had officially announced that his adopted son was his chosen heir, yet despite all the more appropriate partners that had Kai had been introduced to he had still chosen to marry the second born of some unknown group, in their eyes Izumi was just a quirkless useless freak and voiced their opinion to anybody who would listen, not caring if said freak overheard then, after all, what could she, a wife so unloved by her husband that he wouldn't even touch her with gloved hands never mind get revenge on someone who had upset her, hope to ever do to them, if only society didn't base the entirety of a person's worth on whether or not they had a quirk, then those certain groups of individuals might have been able to see Izumi for what she truly was, a trained assassin who could play into the role of a meak quirkless girl so well that no one would ever think that she was the culprit of a poisoning even if she had been the one to pass the victim the poisoned glass of wine or that she could ever have the strength to slash someone's neck even though there was blood still stuck under her nails.

-Kai had enjoyed spoiling Izumi ever since their first meeting, with the young heir always making sure to give his future bride the largest piece of whatever treat they were sharing or letting her choose the games that the would play, as they got older and became teenagers with access to money Kai began to give Izumi material gifts, silk dresses, designer shoes, antique daggers and custom guns among the favourites that he would send to the large penthouse that Izumi and her mother shared, and when they finally became adults, no longer under the watchful eyes of their parents and escorts to make sure that they didn't do anything inappropriate before they wore each other's rings, Kai would spoil Izumi with affection, while Kai was unable to express to Izumi how much he cared while they were out in the city or attending a meeting in fear that his enemies would see her as an attractive target for revenge if they knew he loved her, that all changed when they returned home, with all of Kai's love being saved for when the wedded pair were behind closed doors of the estate and surrounded by allies, unable to keep his hand or his lips off his beloved for very long, often kissing her again and again until Kai lost count of how many times he had felt his lips on her, completely lost in his wonderful pure wife and content with the knowledge that he would get to share the rest of his days with her by his side.

-Kai and Tomura had despised each other fiercely ever since they had been children, with All For One's heir originally being chosen to be the Shie Hassaikai heir's playmate before their disastrous first meeting had taken place, when in the span of 5 minutes while the children had been left alone without any supervision Kai had broken out into hives due to the dust and dirt that Tomura had shoved down his shirt after Kai had used his quirk on the blue-haired boy's Gameboy, or maybe the events had happened the other way around, no one really knew, and so to resolve the issue and improve their alliance Izumi, sweet quirkless Izumi who's smile could rival sunshine, had been sent to replace her brother and the rest was history, as the two heirs grew older their hatred for each other never disappeared, in Kai's eyes Tomura was just an immature man child with few manners and half a mind who didn't deserve the legacy that All For One would eventually leave behind, Tomura, on the other hand, thought Kai was nothing but an emotionless NPC who would never be able to show any true emotions towards his precious sister and force her to languish in a loveless marriage for the rest of her life, the only time that the pair ever appeared to get along was when they were around Izumi, having sworn to cease all arguments and pretend to be civil with each other whenever she was in the same room after seeing how heartbroken she had been as a child when she had found out that her two favourite people in the entire universe didn't get along, the image of her crying face still engraved in their minds to this day and acting as a motivator to not slip up their act; no matter how much they both wanted to use their quirks to kill each other.

-Kai doesn't touch Eri once during the first few months of her life, Izumi had hoped that her husband would see their daughter the same way he saw her, pure and untainted by the sickness of the world, yet no matter how many times she tried to persuade him to stroke Eri's hair or let her hold one of his gloved fingers, Kai still refused to touch her, despite his lack of physical contact with his daughter it was clear to everyone in Kai's inner circle just how much he loved his little girl, Kurono often walking into the main office only to find Overhaul reading out reports and acting as though Eri's giggles and gargles were replies to his comments, Mimic being forced by Overhaul to return to his body multiple times a day whenever Eri wanted to play with his bodysuit and the Eight Bullets left to stare in disbelief every time Overhaul would willing take his mask off whenever she was around so that she wouldn't get scared and cry, it wasn't until the day that Eri said her first word that the physical distance between father and daughter finally changed, when Eri had called out to him, to her dada with her hands stretched high to show that she wanted him to pick her up from her highchair, on that day something changed in Kai as he found himself unable to deny his daughter's request, with little Eri repeating the word several more times as her father got comfortable holding her, from that day on it became common for those in the inner circle to see their boss walking around the estate with his daughter held tightly against his chest, Kai even having Eri sit upon his knee more often than not whenever he conducted business; his excuse when asked by his clients about her presences being that she would have to start her training early if she was going to be the Shie Hassaikai's leader someday, when in reality he just wanted to spend more time with his adorable baby girl.
