Izuku Aizawa is the son of the Pro Hero Eraserhead, Shota Aizawa. The Aizawa family live in a house a on UA campus, due to the nature of his father being a teacher there.

Growing up, he idolized heroes especially All Might, and wanted to help people just like he did, but when he was four, he noticed something… different. He could feel people, that's the best way Izuku could describe it. He told his parents, who decided to check if it really was a quirk and Shota stared at Izuku, erasing it. Everything seemed normal again to young Aizawa, and then Shota blinked and suddenly Izuku felt the presence of his parents once more.

"So, did that do anything?" Shota asked.

"Yeah, but then it came back as soon as you blinked," I responded.

"Interesting, after school, I'll take you to Recovery Girl to see what it is, okay?"

"Oh, my son's finally getting his quirk how exciting," Inko said, "We should celebrate, tonight I'll make your favorite and you can tell me all about it when you get back okay?"

"Okay mom," Izuku said before finishing his breakfast and getting ready for KG-1.

"Don't tell anyone that you have a quirk yet Izuku!" Shota shouted to the disappointment of Izuku. Izuku had quite a few secrets to keep. His father being Eraserhead, his living on UA campus, and now the fact he had a quirk. On all official records he is recorded as Izuku Aizawa, but to everyone else, at least until he gets into UA, he goes by Izuku Midoriya, it being his mother's maiden name.

Despite how much he wanted to share the news Izuku obeyed his father and said nothing about his quirk. Though it was difficult, as Izuku walked he could feel almost everyone around him, except for a few people here and there. A problem Izuku shortly realized that, since his quirk never shut off, he kept using it, and constantly using a quirk makes people tired. Fighting through the tiredness of the day, he was overjoyed when it was time to go home. He went over to get picked up by his mom.

"Oh my, Izuku are you okay?" Inko asked.

"Yeah," he replied, "I'm just very tired." He began walking with her towards UA

"Didn't you get enough sleep last night? When did you go to bed?"

"Right after we watched that All Might video," he yawned.

"You know your father's jealous that you watch that video so much."

"Why? I'd watch a video of him instead if it existed," Inko laughed a bit at that, while Shota had been shown by the media a few times they never caught him in the middle of his job, only ever at the end.

When the two of them made it to their house Izuku decided to sleep some with they waited for Shota to finish. It was around 3:30pm when the front door opened and Shota was there with Hizashi Yamada, and Nemuri Kayama behind him.

"Where's my favorite nephew?" Hizashi asked.

"He's in his room, he was very tired after school," Inko replied. Shota went to go wake up his son and get him ready to visit Recovery Girl. When he came out with him Nemuri and Hizashi giggled.

"What's so funny?" Izuku asked. Inko levitated a small mirror to herself and handed it to her son. When he looked in, he saw the tired eyes of his father staring back at him. Izuku took after his mother mostly except for his eyes, at least that's what they said, but Izuku never really noticed until now.

"He's a tiny you!" Nemuri busted out laughing before being joined by Hizashi.

"How do you feel?" Shota asked.

"Still a little tired, but it's better, I think…" Izuku responded.

"Maybe Recovery Girl will be able to tell us why you're so tired," Shota supplied.

"What are you two doing here?" Izuku finally asked.

"You didn't think I was going to miss my favorite nephew getting his quirk, did you?" Hizashi replied, to which Nemuri agreed. So, they headed towards Recovery Girl's office, when they got there, they found a dog-mouse-bear thing speaking to her.

"Ah, good to see you all, I'm assuming your son's quirk has finally manifested Eraserhead?" it asked.

"Principal Nezu sir, how did you know?" Shota asked.

"Seriously, what kind of principal do you take me for? I've kept track of your son ever since he was born. I knew he should be getting his quirk any day now, then I noticed a look in your eye when I checked your class. Something good had happened. Then when I checked on Mic and Midnight, I noticed they had a slight change in them as well. So now, I knew it had to do with Izuku getting his quirk. Then of course since both you and Inko are first time parents you'd go to a doctor to figure out what the quirk is or what it does or how to deal with it, and the only way you could do that without letting slip who was the boy's father was to come to Recovery Girl," replied Principal Nezu as he sipped his tea. "Now that that's out of the way, why did you tell them and not me?" he asked with a hurt expression.

"Oh, sorry sir, I guess I forgot," Shota replied.

"Well, the good news is I'm here anyway," Nezu replied.

Recovery Girl motioned for Izuku to sit down on the bed, "You look like your father have you been getting enough sleep?"

"Yeah, but today I'm just very tired," Izuku responded"

"How did you know you had a quirk?"

"When I woke up, I could feel my parents in the house. Like seeing without seeing them if that makes sense."

"Has this happened with other people?"

"Yes, everywhere I go I feel most of the people around me."

"Not all?"

"No."

"Now, I'm going to take a little bit of your blood to test, okay?" Izuku nodded. "I'll also need a sample of blood from you Shota," she said receiving a small nod from the man. She took two syringes and took the blood. "Now young man, you can rest a bit while I run some tests on these okay?"
