Izuku looked up from his burnt and bloody hands to see his fath- no, All for one looking down at him with the flames and smoke surrounding his silhouette making him look like a true incarnation of evil. "Izuk-" All for one started only to be interrupted, "You don't get to call me that. You're not my dad." All for one sighs, "I know it's hard, and you're sad about your mother bu-", Izuku interrupts again, "It's your fault Mom is dead. Just kill me already, that's all you do anyways and the only reason why you came back is because you want to make me an evil villain like you, and I would rather die than be a villain. So just kill me already." Izuku finishes and looks back down.
"Izuku. I would never kill you. I love you and your mother more than anything in the entire world.", All for one states. "Then why did you leave?" Izuku asks, And there is deafening silence for a moment before there is a response.
"It had to do with work." "So you left to kill more people?" Izuku rebutts, and All for one does not answer and instead looks away. All for one sighs again. "Izuku, listen. Inko, your mother, is dead, and no matter how amazing quirks may be, she isn't coming back. I'm the only one who is able to take care of you. Don't make me force you to come with me." All for one says. "I don't want to live anymore. Mom is gone and I can't go on and force myself to be a villain and kill just to survive." Izuku states. All for one clenches his fist and suddenly slaps Izuku's cheek, forcing him to look to the side, "Don't ever say you don't want to live! Do you think that Inko would want you to die just because she wasn't alive anymore?!" "You can be whatever you want! I won't force you to be anything you don't to be! So stop trying to die, I'm already going through Inko's death, I can't lose you too!
Tears run down Izuku's as he takes in what All for one said. "I don't believe you." Izuku says. "What?" All for one asks, "I s-said that I don't believe that you love me or Mom! If you did, then M-mom wouldn't be dead! A-and D-dad would have never left a-and made Mom c-cry!" Izuku feels the room suddenly drop several degrees until All for one sees Izuku's tears coming at full force.
All for one suddenly picks up Izuku despite his protests and hugging him to his chest tightly while apologizing, "I'm sorry I ever made you think that I didn't love you and for making your mother cry, Izuku." All for one pulled Izuku closer to him and put out all the fires in the home with a wind quirk and said, " Quirks are like pieces of souls, Izuku. That's why when I take someone's quirk they pass out and adjust to what they lost."All for one wipes Izuku's cheek of tears with his finger before he continues,"I was able to take your mother's quirk before she died. I want you to always have a part of her with you, so here,", Izuku feels something warm, loving and familiar enter his body as well as his eyes starting to tear up again,"Kurogiri is going to take care of you from now on, because I'm dying from my fight with Allmight. I love you Izuku, so I'm going to let you be whatever you want whenever you want. I'm leaving you with my quirk as well as a sentient quirk to be there for you when you get lonely. If you ever get tired of limitless existence, you will be able to pass on your power to someone you deem worthy and you will finally pass on. I love you Izuku and I will always love you, as your father." Izuku looked up and saw his father's smile, then he felt a limitless amount of power and potential enter his body, as well as his mind making room for another. And with it all came a tiny sting as he watched his father blow to the wind in a cloud of ancient dust in front of him as he fell from his father's hands into a purple mist-like portal as his father said his last words, "I am now forever with you as is your mother. I love you, Izuku." "Daddy! Don't leave me again!" Izuku's words were unheard by all as his loving father's quickly fading from disappeared from his vision to be replaced by purple mist.
