Power: Mirio × Reader (Lemon)

Beginnings

We are kids at this time

[F/N] POV


“[F/N], could you heal it?”

Tamaki sniffled as he showed me a scrape on his knee. I nod with a small smile as I activated my quirk. I had two horns, hidden in my hair, they got slightly longer as the scrapes disappeared.

“Thanks, I wish I had a quirk like yours. With that, I could actually help people.”

“I’m sure you’ll be able to fight bad guys with your quirk big bro.”

“I don’t know.”

“I believe in you. You will become a great hero.”

After mom and dad found out about my quirk they became nervous. I had to go to the Hero Association a lot. Mom said that my power wasn’t easy to control. But I had used it easily enough, why were they afraid? We decided to move to be closer to the Hero’s, so it would be less of a drive. Every time they seemed to be shocked at how well I controlled my power. The Hero Eraserhead kept an eye on me when I visited. He was actually pretty nice, despite the fact that he looked like he didn’t sleep.

“Mr. Eraserhead?”

“hmm? What is it [F/N]?”

“Why is everyone afraid? When can I go home?”

“Your power is unknown to many of us. You should be able to go home tomorrow if your parents don’t extend your stay again.”

“Do you think that they will? I miss Tamaki, I don’t like being alone.”

He sighed, “I know kid, but try to understand that they are doing what they think is best for you.”

I start to cry and he hugs me, “I’m sorry Eraserhead.”

He smiles, “How about we take you to see All Might?”

My eyes light up, “Really!? The number one hero?”

He got up and took me to the infirmary. He sat me next to him as he was sleeping. He had some scrapes, cuts, and bruises. Eraserhead looked at me and nodded. My horns grew slightly as I began healing him.

“Good, be careful not to use it too much.”

I nod and once the last cut healed I stopped.

“You are doing a fine job…and I think that you might just make it in the Hero businesses.”

I smile and All Might sits up, “So this is the young Hero that I keep hearing so much about?”

“I-I don’t know. My name is [F/N]…N-Nice to meet you All Might.”

He jumps up with a pose, “The pleasure is all mine young [F/N]. I hear you have a unique quirk, be sure to always use it for good. Do you know why?”

“Because there are too many of the bad.”

His eyes widen slightly, “You are a smart little one. I’ll be sure to keep an eye on your progress.”

I nodded and Eraserhead sits next to me, “Let us try again.”

He points to his eyes and I reverse the dryness. He thanked me and All Might did the same before Eraserhead took me back. He left and I sigh in this lonely room. 9 years had passed. Why haven’t any of my family contacted me? Aizawa started teaching so I was even more lonely. I missed big brother. I waited until dark and snuck out. I made it home and went up to Tamaki's room. He was asleep so I nudged him.

“Tamaki?”

He sat up shocked, “[F/N], How?”

“I missed you.”

“No, How? Mom said that –“

He seemed sad and I looked at him and he had many bandages. I reverse it quickly and then I heard another presence in his room. I see a blonde boy with beady blue eyes.

“Who is this Tamaki?” The boy asks.

“My little sister. She…she isn’t supposed to be known about by anyone so please keep this a secret.”

The boy looks at me and I notice that he is bandaged up as well.

“Do you want me to heal you?”

He smiles wide, “Yes please.”

I reversed it and he stared in awe, “You have a rare quirk, no wonder it’s a secret. My name is Mirio and I aspire to save a million lives.”

“My name is [F/N].”

“That is a nice name. I hope to see you again soon.”

He yawns and suddenly gray fabric is wrapped around me along with a menacing aura. I look over to see red eyes.

“How the hell did you get out [F/N]. You know the rules.”

My parents came in shocked, “W-Why is she here. Eraserhead explain this!”

“It's my mistake, I apologize for the inconvenience.”

“It could of hurt our son. Do you not understand the-“

“She wouldn’t, she is well controlled on her own. [F/N] is-“

I am shocked, “Eraserhead…was I ever to come back home?”

The look on his face said it all. We left and I couldn’t help but cry. Aizawa seemed bothered as well.

“I’m sorry [F/N], your parents were afraid so they sent you to us…to protect Tamaki. I knew that you’re in control…but they didn’t. Many fear the unknown.”

He hugs me, “I’m not one for the mushy stuff but I think you need this.”

I grip onto him, continuing to cry.
