Chapter 1

Quirk Name: Transfer Healing; Transfers physical drawbacks onto the body of the user, healing them on their own body. The longest time for a severe open wound to heal is seven (7) minutes. For this to work, the user has to be touching the person's DNA. If the user has more than one person's DNA, the user heals them all, they cannot choose. If a person dies, the user of Transfer Healing can take their wounds, but dies, giving the dead their life.

Drawbacks: Taking wounds is extremely dangerous, especially when the person healed has low stamina. The user replenishes stamina, at the price of giving their own away. If the user dies, the healing effects are terminated, but wounds are kept on their body, not returned. Transfer Healing does not heal the user's own wounds, only foreign wounds. The user of the quirk also has higher nerve sensitivity.

Y/n smiled nervously as he stood, staring in awe at the giant building of UA High. Many students were already heading inside, chattering excitedly as they found their friends. Since this was his first year, Y/n didn't really know where to go, even if he's been to the school before. "I have to go to 1-A... but I don't know where that is..." he muttered, feeling himself shrink.
He was shy, but it didn't seem fitting for his physique. Since he originally was from C/n, he was taller than most of the Japanese, already 6"5. It was annoying to be so shy in such a noticeable body.
Y/n smiled shakily at a few passing students as he started towards the entrance. He watched as people walked down the halls, noticing a few people he'd seen in the entrance exam he did a week before. He couldn't go to school because his father wanted him to stay home. And since his dad was a teacher at UA, he couldn't really say no. He followed the other students quietly, looking out for 1-A all the while. Soon enough, he found the door, and was surprised by the size of it. But surely he wasn't the tallest person. There might be someone with a mutation quirk after all.
He opened the door and was greeted by the stares of the class.
Y/n promptly slammed the door closed, his face heating up dangerously. He slowly backed away from the door, turning and jogging back the way he came. He yelped when a familiar scarf yanked him back towards the class. He dragged his feet, forcing the scarf to drag him into the class backwards, facing away from the class.
"Aizawa, nice of you to join us. Introduce yourself." The class gasped when Y/n's adoptive father, Aizawa Shouta, called him by his last name.
"What?! Are you saying this guy is your kid?"
"Aizawa-sensei! I didn't know you had a kid!"
"Who are you married to, Aizawa-sensei?!"
Second person POV
You flinched at that question, glancing to the side and seeing your father sigh. "I'm not married to anyone, Kaminari." You flinch again, shivering in fear. You feel yourself slouching instinctively, but your father's scarf straightens your back.
The kid dad called 'Kaminari' spoke up again. "If you're not married to anyone, then how do you have a kid?" Then you hear a slap and Kaminari yells in pain. "I have a kid because I adopted him, Kaminari. And thank you, Jirou. Now, introduce yourself, Aizawa."
You take a deep breath, trying to calm down before you turn around. To stall for time, you write out your name on the board, then you quickly turn. "Hello- hello everyone. I'm- my name is Aizawa Y/n. Please just- please call me Y/n, and please um- take c-c-care of me!" You stutter out, all in one breath. You spoke super quickly, and it seemed that some of the class didn't understand what you said. Well, too late for that now. You quickly made your way to the very back, where there was a single seat in the corner.
Even when you were at the back, you somehow felt eyes on you throughout homeroom, and English as well. You couldn't focus well, but Yamada knew you well enough, and didn't bother you except to give you notes.
That all ended when Toshinori, All Might that is, called for the class to put on their Hero Costumes. Seeing as Aizawa was your dad, you were perfectly ready. Your hero costume was a white lab coat with pastel f/c lapels that hung to your knees, and sleeves that reached your elbows. You wore a dark f/c turtleneck shirt that was thin and breathable and had long sleeves to your wrists, and gloves that were fingerless and the same colour. Your cargo pants were white, with pastel f/c pockets. Most of the pockets held bandages, antibacterial cream, and small smoke and flash grenades. You also had a thick leather belt that hung snugly around your waist. It had small compartments that dissolved dna in a water solution that went under your shirt and touched your skin. That way, whoever's DNA you put in those compartments, you could heal. It would have been awkward to ask your classmates for a peice of their hair, but it would be worse if they got hurt during the excersise and you didn't do anything. To top your costume off, you had a Captain's hat with a large f/c cross, so people immediately know that you are the doctor.
You looked around, feeling quite out of place. You still needed DNA for your quirk to work.
So, you sucked up your fear and you decided to ask a male in a bunny-suit for a peice of his hair. "Um- hi, can I- uh, I'm Y/n, what's- what's your name?"
he jumped, eyes nervous underneath his mask. "U-uh! M-my name's Midoriya! Nice to met you Y/n-kun!" He bowed stiffly, multiple times. You waved your arms about, assuring him that he didn't need to bow. he apologized, then you apologized, and you both turned away from each other, faces red with embarrasment. The rest of the class watched awkwardly, slightly amused by how similar their personalities were, while their height was completely opposite. You didn't notice, seeing as how you were berating yourself with how awkward the situation was. You took a grounding breath and you quickly turned to Midoriya. "Um. Midoriya-sama. Can I please have some of your hair?"
Midoriya seemed to process and reboot what you said. "Eh? Hair? Sure. No offence, but that's a weird ask." Midoriya pulled off two strands of his hair, handing it to you carefully. Your eyes gleamed at the two strands of shiny green hair. This would give you enough DNA to heal him with for months!
"Thank you, Midoriya-sama!"
You skip off, carefully winding the hairs together and placing it in one of the 25 compartments on your belt, next to your father's. You hear Midoriya suddenly yelling something. "Eh?! Sama?! Eh?!"
Encouraged by the interaction you had with Midoriya-sama, you approached a random guy with a cool costume that looked like he had grenades for arms.
You tapped him on the shoulder, smiling, not noticing his intimidating glare as he scowled up at you.
"Hello, uh. I'm Y/n, what's your name?"
He scoffed, a sneer forming on his handsome face. "Fuck off, nerd. Go bother someone else." Your smile dropped, quickly replaced with a panicked grimace.
"Um- sorry I- I didn't m-mean-" Toshi- All Might quickly approached when he saw you were flinching from seemingly nothing. "Hello, young Aizawa! What seems to be the problem?!"
You just looked up, slouching instinctively. "Noth- nothing, sensei- I was j-just-ju-jus-just-"
"Hey, hey, it's okay! Talk slowly, young Aizawa. Just calm down. That's it." All Might lowered his voice. Those watching were awed at how uncharacteristic it was. They also glared at Bakugo, who looked almost offended. "What?! It's not my fault Aiza- Y/n's a pussy!" You flinched again, and All Might turned to Bakugo, his smile tight. "Young Bakugo, could you please refrain from calling others rude names? Especially young Aizawa. He- Nevermind."
He turned back to you. You were hiding behind his back because he was a lot taller and wider than you were. "Now, young Aizawa, what did you want to say to young Bakugo?"
You bit your lip, looking down rubbing your tingling arm. "Uhm, Bakugo-sama. C-can I. Can I have a peice of your hair, please? It's for my- my quirk."
Bakugo scowled, about to say something mean, when he met All Might's eyes. He sighed, gritting his teeth as he pulled out a few hairs. "Here. Leave me alone, dammit."
You bowed, quickly walking away from the intimidating teen. You could still feel his glare, so you just stayed behind All Might.
You couldn't really deal with speaking to others anymore. He told the class to pick lots and he let you just stay behind him. "Young Aizawa, can you be a hostage for the villains? You can use your quirk on people, but they have to touch you first, okay?"
You nodded, fiddling with a roll of bandages. The class all drew lots, and All Might held a box with letters in it for teams to go against each other.
"Alright! Hero team: Team A! Villain team: Team D!" Midoriya and Bakugo stare at each other. You had a bad feeling about this match.
