Izuku Midoriya

"Don't run, please!" Izuku called after the five-year-old boy. His son was a runner these days. The small boy was currently toddling through the house and climbing the stairs towards his bedroom. Life over the past few years had become routine, comfortable, and rather quiet. Dabi treaded his son kindly, still under the impression that the growing child was his own flesh and blood. The Omega knew better but didn't have many options. To the child, Dabi was his father.

"M'kay, Mama," the young boy slowed his pace and carefully climbed them this time. His small hand gripped the railing as he hiked his short legs up one at a time while ascending the carpeted stairs. 

"Karu, come back down once you get your toy," he called up the stairs as the green mop of hair disappeared behind the bedroom door.

"Kay!" Karu called back before the familiar sound of a toybox being opened muffled out any more communication they could have. For a long time after Karu was born, Dabi let Izuku stay home and raise him, but once the child was old enough to begin school, tutors were brought in during the day and the Omega was made to work.

It was almost time for another workday, and Izuku was getting Karu ready for the tutor to arrive. Dabi had departed already. The house they recently moved to was to keep up some form of normalcy for Karu. It wasn't any kind of neighborhood or street they lived on, no. The house was built in an underground location that the League of Villans owned. It was a quick walk through some tunnels and then he would arrive where the group held all their meetings. 

Izuku had no choice but to work for the League, and after a while, he stopped caring in general. This was his life now, and any form of rebellion put Karu at risk. Dabi never threatened to hurt the boy. To the Alpha, that Karu was his son. Dabi only ever threatened to take Karu away from Izuku, and that was enough motivation for him to obey. 

"Mama, I'm rwedy. Mrs. Sagi here?" Karu asked while coming down the stairs. His backpack was slung over his shoulder, most likely stuffed full of toys and his school work. Izuku smiled and took his son's hand once he reached the bottom of the stairs.

"No, Mrs. Sagi isn't here yet. She'll be here soon," he soothed his overly excited son. Karu had just turned five, and his quirk had yet to manifest. Izuku wasn't in a rush for that though. They had gotten lucky with Karu's physical appearance taking after Izuku rather than Katsuki, but he knew that if his son had a quirk that it would be genetically similar to Katsuki's since Izuku was born without one. 

Thoughts of Katsuki still haunted him from time to time, but eventually, those thoughts began to fade. Izuku had a new life now, and he had long given up his prayers. No one was going to find them or rescue them. No one was coming and this was their new reality. He squeezed Karu's hand as Mrs. Sagi knocked on the front door and entered. As far as villains went, he was glad Mrs. Sagi was someone the Omega at least felt comfortable with. She was great with Karu, and Izuku didn't have any qualms leaving his son with her. Not that he had much of a choice. 

"Mrs. Sagi! I bwought my toys! I bwought my cars and the stuffed bear Mama gave me when I was wittle!" Karu took off towards his tutor and Izuku smiled at his son's eagerness. He was bright as can be, and the Omega wondered if Karu got that from himself or Katsuki. Katsuki had always been intelligent, but so had Izuku. He had trouble remembering his younger years, and as time continued to pass him by, Izuku just let those thoughts drift away. They were too painful to try and keep alive.

"Come give me a hug before I go to work," he called after his son and watched as the young boy's feet planted in the carpet before Karu swiveled around and bolted back into Izuku's arms. The greenette had to bend down to hug him, and took a moment to breathe in his soft scent. It wouldn't change until he was 12 and his sub-gender revealed itself.  Izuku wasn't rushing things though and never took for granted each moment he had with Karu. He never knew what might be his last. 

"See you later, baby. I love you. Be good, learn a lot, and stay safe," he whispered before pressing a soft kiss into Karu's unruly curls. Then, he was off. It didn't take long, and soon he was taking a seat next to Dabi at the conference table. The group seemed to be already in a heated discussion about an upcoming mission. The League had been quiet for years, staying hidden and recruiting new members to do their work for them while the mains stayed hidden. Izuku had his theories about why they did this, and he knew it was because they had taken him and Karu. They needed time for people to forget and for identities to be concealed. That was why he and his son had never been outside since Karu was born. 

"How was Karu this morning?" Dabi leaned over and kissed his cheek, a soft hum leaving the Omega's throat at the action. 

"He was fine. Excited to see his tutor like always," he replied before opening up the folder in front of him. Whatever case they were about to embark on must have been important enough, because they never really involved the Omega unless it was for information.

"This is the outline of what we're planning. You've been out of the media's eye for five years now, and it's time we begin our mission once again. We've given you a new profile, and though it would have been much easier to just give you a new look, cut your hair, and change your eye color with some contacts, I love the way you look and don't want to ruin it. Instead, we've had a suit made. I know you haven't been on any missions with us yet, but you have been training still with us and so I know you will handle this well. Tomorrow, we are going to U.A. The school is still standing, spreading its filth among those students like a disease. The new class of students need to know who the Leave of Villans really is." Izuku looked through the folder where images of his new suit were mapped out. It was black with purple bolts around his ankles and wrists. Somehow, the Omega knew Dabi designed his suit to match with his own. The Alpha was possessive of what belonged to him.

"What are we going to be doing?" he asked while flipping past the suit design and onto the notes. Tomura chuckled and leaned his elbows on the table while scanning the notes himself. Dabi shifted slightly to give him room and Izuku waited for their leader to give more instructions. 

"We are going to take down Erasure Head while he is on a field trip with his new class. Your job will be to hold off the kiddos while we capture and take down the teacher. You've been so good with children, Bunny," he cooed against his ear before Dabi shoved him away with a low growl. The possessive Alpha tugged Izuku closer and snaked an arm around his waist. 

"What that jackass is trying to say, is that we don't want to kill the kids, just hold them back. We want them to see their dear professor get taken down so they know who really is in control. I know you can handle this simple task, babe. I know you could never harm a child, and these brutes just don't care. We wouldn't want anything bad to happen to innocent children now, would we? Think about Karu —" the Alpha said lowly, and Izuku realized the all-too-familiar threat in his tone. Dabi wasn't above harming kids. Anyone other than Karu would easily feel the Alpha's wrath, but the Omega knew first-hand that he wouldn't hesitate when it came to putting Izuku in his place. The greenette had a powerful quirk, but was still bound by two things that would always put Dabi at an advantage — is sub-gender and Karu. 

"I'll do it. I never said I wouldn't do it." Izuku looked at the image of Aizawa. It must have been recent because the professor had changed. His usual black hair had a faint dusting of grey on the roots. Five years didn't seem like a lot of time, but for a hero it was. He looked strong as ever, tired too. The bags under his eyes hadn't gotten better with time, and Izuku swallowed the lump suddenly forming in his throat."I always wanted to get back at him for giving so much homework anyway."

"That's the spirit, Bunny. I will bring your suit home tonight with me. You should read over the notes and get your training done for the day. Then go home and rest. I'll be home with dinner later," Dabi turned Izuku's face until their lips connected, and he closed his eyes. There were a few things he got used to over the years. The Alpha's physical affection soon became tolerable and even welcomed at some points. At first, he fought it off. Each touch made him scream, every kiss made him want to bite back and scratch, but soon he realized it only caused him more pain and Izuku didn't want Karu witnessing the violence that always bred between him and Dabi. 

Izuku learned quickly to obey and do as he was told. It was for Karu, and the Omega didn't regret a single thing. He would do it all over again if it meant his son was safe and happy. The kisses they shared were soft and almost loving. If Izuku didn't know the man's true colors, he would have believed the Alpha actually loved him. Sex was still something he hated, but mainly because he couldn't relax. Every time the Alpha engaged sexually with him, he thought of the nights he cried in pain as Dabi took advantage of his body. Still, he didn't fight it off anymore, and on the rare occasions when his body craved release, he actually was the first to seek Dabi out for satisfaction. 

The only good thing about the situation was that Izuku couldn't get pregnant anymore. Karu's birth had been damaging and stressful. The doctors told him he would have to stay on birth control and that getting pregnant could kill him this time around. Izuku didn't bother explaining that the pregnancy was so rough because he was being raped and held prisoner the entire time. He didn't want to get pregnant again and gladly took the shots every three months. Karu was enough for him, and as long as his baby was healthy then Izuku would be happy. 

His training didn't last long, and Izuku was eager to get home with his son. It was the only time he smiled anymore. Karu was his only piece of happiness, and the only thing keeping him going. As soon as he walked through the front door, he heard the pittering of little feet on the floor and the shrill sound of his son's voice rushing his way.

Little arms wrapped around his legs and Izuku's blank expression pulled into a smile as Karu began babbling about all the things he was learning from his tutor. The sound of his happy voice was enough to make the Omega temporarily forget  Dabi, the mission, and all the swarming memories of his time at U.A. before he was taken. That part of his life was over, and Izuku knew it would never resurface. Leaving work at the door, Izuku kicked off his shoes and scooped his son into his arm, relishing in the bubbly laugh that escaped Karu's lips. For now, this was his happiness. Tomorrow when they would raid U.A, and when he would force those children to watch the slaughter of their professor, Izuku would remember that this was his happiness. Karu was his happiness. It was for Karu. Everything he did was all for Karu.
