Inko took Eri from Hisashi and carried her upstairs to tuck her into bed and so the two of them decided to sit at the dining table in the apartment.
"Dad, are you going to explain how I ended up with a new sister?" Izuku was a little overwhelmed by everything.
Hisashi smiled and sighed with a sorrowful gaze, "she was running away from a bad man. A yakuza member that I recognized from some old connections. You remember me talking about Yoichi?"
"That he was always sick and frail growing up before he died?" He knew this was a subject his father hated bringing up.
"Eri had those same eyes that wanted to live, know more than a hospital bed to grow up happily. Izuku was covered in scars across her body that were things a child should never know." Hisashi's voice shaked with disdain throughout.
"So you saved her from him." Izuku was wondering why the tone was so sombre.
"I did." He answered with a soft smile.
"So isn't the yakuza going to be after you because of this?" Realisation hit him as he wondered how his father would deal with angering the Yakuza.
"Izuku, he won't be a problem." There was a grim chuckle that brought an assurance to a permanent solution.
"Dad, what did you do?" Izuku felt a seed of dread grow in throat as his father's red eyes flashed with a cruel glimmer.
"Promise you won't be afraid?" His face turned to one of hope and caution.
Izuku gulped nervously and nodded. "Okay."
"I killed him Izuku. That's the truth of the matter." The bluntness almost made it seem like Hisashi joked about it.
His brain went blank, his father the kind man who loved to laugh and share stories of his childhood… killed a man?
"Does mum know?" Izuku asked, wondering how he would have been able to save his new sister and kill the Yakuza.
Hisashi just nodded.
"H-How can you both come home so easily knowing that you killed a man?" His voice trembled at the prospect that he may have never known who his parents actually were.
"Because there's things so much worse that your mother knows about me." Hisashi locked eyes with Izuku and then took a deep breath. "So you are using HyperTech, I'll be honest I didn't think you would receive a 'system' as well. Do you want to talk about the day you got yours?"
Izuku's blood went cold and the colour drained from his face. "What do you mean 'system'?" Trying his best he feigned ignorance.
"Izuku, don't lie to me. You had always been a careful child even if you had a reckless streak that contradicted it. Choosing a cafe out of nowhere doesn't make sense." Hisashi seemed adamant to extract the truth from him.
"I-I…" Izuku bit his lip not wanting to admit the truth of that day. "I wanted to die. Everything felt hopeless and being rejected from every school just felt like it locked out any hope. Then I woke up and that-" He's cut off by a jolting pain in his head.
"Host is not permitted to talk about the system with others!" The system rang out.
Hisashi placed a hand on his shoulder and soon a warm feeling soothed the shock he felt. Then Izuku realised he had not even seen his father get up from his chair. "I forget new users cannot talk about their systems. I'm sorry I wasn't here to be by your side when you felt like that." He wrapped his arms around Izuku and just hugged him.
It felt like the emotions he kept holding into lies to himself and to others that he was distracted with the system came washing over him. Inko stood at the door frame with a sorrowful expression not daring to step into the movement. She had her suspicions but she would rather not confirm them after all the 'system' only latches on those in despair. If Izuku was pushed to that brink, she failed her role as a mother.
Slowly the tears stopped and he wiped away the rest of them. "I'm sorry for crying dad."
Hisashi just gave a comforting smile and ruffled his hair. "Even the strongest have to cry sometimes. But is your system just focused on the cafe, at least see if you can confess that."
Hesitantly he nodded and Hisashi seemed to relax. "I was scared that you may have in fact gained the cafe as a simple step into the next stage."
Izuku was confused at first because his father knew about the 'system' but it seemed he knew so much more. "What do you mean next stage?"
"I guess I better share the system that I'm assigned to… 'Monarch of Villainy' it's been this way for two hundred years." Hisashi said with a grim expression.
"'Villainy' what do you mean? Are you a villain?" His father was not only a 'system' user but also a villain.
"Izuku tell me if you recognize the name 'All For One'?" Hisashi held only the utmost sincerity in his question as if already knew the answer.
Izuku growing up quirkless in a place filled with quirks and where he as an outlier was desperate to fit in tried every method to be a hero. Scouring the internet growing up there were tales amongst the quirkless of a 'paragon' or 'devil' a being that if you made a deal with you could get a quirk and finally be… normal. The name of that entity was 'All For One' a being who at a touch could deprive a person of a quirk and grant one for another. A boogeyman inscribed into the old wives tales and warnings given to children…. After all imagine the chaos a man who could take quirks could cause.
"What does that have to do with everything?" He asked not wanting to know his father's reply.
"You can already guess." Hisashi stood up and went to the kitchen and put the kettle on as they stayed where they were for a few moments. Then Izuku felt a softer hand on his shoulder and his mum looked at him with sympathy.
"Zuku, I know you must be feeling overwhelmed but your father isn't a bad man." Inko reassured him as Hisashi placed a cup of tea beside the two of them. "He just had a lot of difficult choices to make."
Hisashi sat back down with his own tea. "I'm telling you all of this because I need you to know that no matter the assignment you're given I want to help you. I know how cruel the missions can be."
"Dad… if you could give quirks why did you never give me one?" Izuku thought he had accepted his quirklessness but it was apparent that was another lie. "I could have been normal, I could have played with the other kids…" He had been interrupted by a small hiccup. "Kacchan would still be my friend."
"Izuku I wanted to but the fact is your body is completely incapable of handling a quirk."
Guess he really was a 'Deku' afterall…
"Izuku stop that, I can see what's happening. You aren't useless or lesser because you have no quirk. You're my baby boy and you're perfect as you are." He was kneeled down by Izuku and put a hand to his cheek. "Besides you have a 'system' you'll be better than any quirk no matter what you do."
Izuku smiled a little at his father's words. "Thanks dad. I'm just trying to process everything. You have a 'system', are two hundred at least, a villain, killed a man today, adopted a new child and my body is literally physically incapable of even obtaining a quirk through means that sound like fiction."
Hisashi chuckled, not a grim one but one of pure amusement. "You say that like, humanity had not spent millennia seeing supernatural powers like quirks themselves as fiction. Now what do you say you sleep on this new information and we call it a day?"
Izuku nodded the violent amount of emotional stress was too much but one question did sit in his mind. "Dad, what's my sister's name?"
Hisashi looked at him dumbly before bursting out laughing. "I can't believe I forgot to tell you her name. She's Eri and she's the newest Midoriya."
Izuku happily went to his room to sleep and process everything he was told as Hisashi and Inko looked at each other.
"You haven't told him any of the things he needed to know and just threw all the most obscure things about you at once. You'll need to tell him about Tomura or how you are dying." Inko had tears in her eyes as she held her husband.
"I'll tell him in time… just let him keep the innocence of his new friend and let him be happy. He needed to know he would not have to persist with the whims of the system on his own. You remember how many times it ruined our date nights." He joked as he hugged his beloved wife.
"Don't remind me." Inko laughed crying in his arms as they enjoyed each other's presence. Her husband was still with her and all that dread she felt in the last five years after his battle was gone. For now she would happily enjoy the fact her family had gotten a little larger and now they could be a proper family. Afterall Eri had mistakenly solved the injuries of her husband and that little ray of sunshine would make a wonderful addition to the overly emotional family of six. Even if two of them did not even know they were in the family.
