Izuku sat down next to his dorm room desk and let out a long sigh. He felt like he had achieved so much today, finally getting his provisional license. As he thought about how exited Inko had been, and how proud All Might sounded, he took a look at the picture of his father, Hisashi. "I wished you could be here dad" Izuku whispered and decided to replay one of the videos on Hisashi's camera recorder.
For half an hour Izuku just relaxed as he watched through the videos. That was until one thought surfaced out of nowhere and forced Izuku to make a connection he hadn't even considered. He tried to push it aside, but the thought wouldn't go away. As Izuku continued hearing the voice of his father speak in the background, he thought back to the day when All for one and All Might had their final fight. "That voice, it can't be…" Izuku uttered in disbelief. "No, it's impossible, there is no way. He can't be…" Izuku continued as all the knowledge he had about his father was put into new light. "Not liking to be photographed, injury six years ago, leaving us, wearing suits, that voice, All Might's reaction…" Izuku started muttering in near panic. Suddenly, Izuku quickly put all that he had from his father in a box and hurriedly called All Might. "All Might! Quick, meet me outside the main entrance!" Izuku shouted with urgency, not even waiting for any response before hanging up.
When Izuku arrived at the main entrance he met a very concerned All Might. "Midoriya! What's the matter?" He asked. "I'll tell you, but we need to speak somewhere private. No one can know this if it's true. No one can know… he knows…" Izuku blurted out and started hyperventilating. "Midoriya, look at me" All Might said and firmly grabbed Izuku. "Breathe" All Might calmly said. "Remember to breathe" He repeated slowly as Izuku calmed down. "Let's go to the teachers' lounge. There you can tell me what is making you so upset" All Might said calmly as he and Izuku made their way into the UA building.
"Now, will you tell me what is so urgent you can't wait for me to respond over the phone?" All Might asked once he and Izuku sat down. "Where do I even begin?" Izuku asked himself. "You remember that you thought my dad sounded familiar?" He asked, receiving a nod from All Might. "I think I know why, and it is not good at all" Izuku said an pulled a stack of letter out of the box. "After leaving me and mom he kept sending us a check and a handwritten and signed letter once a month, every month. However, on April, six years ago, something changed" Izuku explained as he laid out a series of letter in front of All Might. "That April the letter wasn't written by him but someone else. Then, eight months later, it was him who wrote the letters again, but this time it was like his hand was injured and shaking while writing. Over the following year his handwriting improved back to normal and continued that way. That was until this month's letter, which is back to the unknown person's handwriting" Izuku explained. "When did you fight All for one the first time?" He asked.
All Might had an almost horrified expression as he realized what Izuku was suggesting. "It was late in February six year ago" All Might said. "But this can't be right. It could just be a coincidence" He proposed. "I whish that was the case, but there's more" Izuku said in a solemn tone and pulled out the camera recorder. "Listen to his voice, now with All for one in mind" He said and played a video. This time, both of them heard the uncanny resemblance of All for one's voice, but speaking in a way they never thought he would speak. "And finally…" Izuku said and pulled out the framed picture of Hisashi without showing it to All Might. "Despite him not ever wanting to be taken picture of, my mom managed to take one single picture. Is this how All for one used to look?" Izuku asked and turned the picture around so that All Might could see it.
All Might immediately tensed up as he saw the face of his nemesis that had been burned into his mind. He quickly looked between the photo of Hisashi and Izuku, unable to not see the resemblance anymore. "So it's true" Izuku uttered. "All for one is my father" He said, horrified over the fact. "I understand if you don't want anything to do with me anymore. I mean I'm…" Izuku began, but was cut off when All Might embraced him with his one uninjured arm. "Don't ever put yourself down like over something that is out of your control. You are my successor and I'll be proud of you no matter what. Nothing could ever change that. You're not your father and your father is most definitely not you. He doesn't define you. This is simply a fact we now have to find a way to deal with" All Might said.
Izuku sat quietly for a long while in All Might's embrace before returning the favour. "Thank you All Might. You're right. I'll make my own destiny" Izuku said as the two let go. "That is nice to hear young Midoriya. We can figure out what to do later. For now, go back to your friends and relax" All Might said. "Actually, I have and idea for what to do next" Izuku said. "Or, it is more of a thing I have to do, if I want to move on" He added. "And that is?" All Might asked. "I need to speak with him. I need to speak with All for one" Izuku replied.
