Deep within the lab of Kyudai Garaki, rested a large testing chamber each filled high-end Nomu.

"Doctor Garaki, you've called?" Deku asked in a bored tone.

"I thought Master Tomura would be coming," The doctor sighed.

"He didn't feel like coming so he sent me instead, is there a problem," Deku smiled.

"No, but I finished a small side passion project," The doctor chuckled, while Deku simply rolled his eyes.

With a press of a button, a test chamber rose from the floor, and inside was a human figure floating in some chemical fluid. Sadly the frost covered the glass blocking the view of the thing inside.

"What is that, another Nomu?" Deku asked curiously.

"Not just any Nomu, but my first perfected synthetic human," Garaki announced.

As hot steam melted away the frost revealing a beautiful human woman suspended in the chamber. Izuku's cheeks brightened slightly as he stepped closer to the chamber. This human has beautiful flowing H/c hair and smooth S/c skin.

"Beautiful isn't she," the doctor chuckled.

Deku simply nodded as he stared at the creature, the doctor explained that his creation's name and was going to be given to the league for a test run. But his words went into deaf ears as Deku held the sleeping girl.

________________

(3 months later)

The league and Midoriya tested Y/n and her vector quirk. Her vectors could slice through the Nomu with ease, without even moving an inch. Deku wrote frantically in his notebook as his love and obsession for this grower. There was just one flaw with her, her curiosity. The doctor said he wired her to be like the Nomu, subservient. Yet she would ask him things, anything. That's what he loved and hated about her. She thought highly of him and would ask him questions of anything that came to her, but Deku worried her curiosity would lead her away from him. So he busied her with training and random activities, like cooking and cleaning. Dabi would always laugh that Deku was turning the synthetic human into a housewife.

Till one day the League captured a young hero from his mission. A hero Named Lemillion. He was strapped down to a chair with a quirk canceling collar. And little did they know Deku's fears slowly came true. Y/n would talk to the hero, ask him things. From why he became a hero to what are people like. At first, Mirio was suspicious of her, but somehow she wiggled past his defenses.

"So what lead you to villainy?" Mirio asked.

"I was ordered to. I wasn't born like you, I was created. And my master said I was created to serve Tomura," Y/n explained.

"What do you mean?" Mirio asked.

"I think Master and Deku called me a synthetic human. I wasn't born from the womb," Y/n answered.

"Do you enjoy what you do?" Mirio asked.

"I don't know, I haven't been in the field yet, and I have nothing else to compare to my life up till this very moment. Though I do enjoy talking to you and cooking is fun," y/n chuckled quietly.

"Then why don't you just go and wander outside?"

"Then I would be disobeying. Which is going against my purpose," Y/n gasped.

Mirio's heart broke for this person as he watched her hands tremble slightly. Before Mirio could speak a grouchy voice cut through the air.

"Y/n what are you doing? I thought I told you to train!" Tomura growled.

"Don't worry, I'll fix things," Deku smiled, as he grabbed Y/n's hands.

Mirio watch with worried and sad eyes as Y/n was dragged away. Y/n covered her ears as Mirio's tortured screams.

"Your lucky it was him getting the front of it. I told you didn't I. Your curiosity will get you killed, and remember It wouldn't be hard to replace you. Garaki could easily make another synthetic human, so your lucky I'm sticking out for you," Deku said in a dead tone.

"Of course," Y/n said quietly.

"You know why we do what we do, to get rid of those false hero's. Lemillion is probably just being kind to you to escape. He's tricking you, but as long as you stick close to me none can hurt you, lie to you, o-or drag you down a-and crush you," Deku ranted.

"Why did you become a hero uumm?" Y/n asked curiously.

"Because I wanted to save One million people, and my name is Lemillion," Mirio explained with a tired smile.

"That's so nice of you, Deku told me that all the heroes are just helping people to gain fame and wealth," Y/n said.

"Maybe some, but many people have very entirely different reasons for becoming a hero. Were all different,"

"of course Deku-"

"I told you to call me Izuku," Deku stated.

"Yes, Izuku,"

"*sigh* Your so perfect you know that," He sighed as he pulled her close, a blush on his freckled cheeks.

--------

Mirio sat in the darkness when he opened his eyes to see a rectangular slit of light entering his prison.

"Oh it's you y/n," Mirio smiled weakly.

"I um... Made you some dumplings. I found some berries and leftover flour," Y/n said nervesly as she sat down in front of him.

"They smell great," Mirio smiled.

"I um.. I forgot you were strapped to your chair, so I can just feed these to you," Y/n said with a slight blush.

She took a generous scoop and nervesly feed it to Mirio. He smiled as he happily at the food Y/n offered, it was certainly better than the questionable food the villains gave him.

"That was amazing Y/n," Mirio praised.

"I should have asked what you liked. With some chicken and eggs I could make a mean souffle," Y/n smiled weakly.

"You have a cute smile you know that," Mirio admired, with a light blush.

Y/n smiled more as she feeds him the last bite of the dumplings.

"I hope the Hero's save you soon, so you can go save those Millions of people," Y/n sighed as her smile faltered slightly.

Mirio's smile faltered too as he stared at the bruises that spotted up her arms and neck. Yes, he wanted to get out of here, but he didn't want to leave Y/n in this place. But before he could say anything the wall was obliterated.

"SMASH!!" said a powerful voice.

"All Might!" Mirio Gasped.

Things were happening to fast when All Might delivered a strong punch to the stomach as it sent her flying into a wall. Y/n vision quickly turned black.

------------

"Y/n," A kind voice called.

Y/n slowly opened her eyes to see Mirio smiling at her as he slowly sat her up. As she took in her surroundings, she quickly put together that she wasn't at the hideout. But an office with a lot of windows.

"Mirio... Where am I?" Y/n asked slowly.

"Ah, miss Y/n. It's good to see your awake," said a bear mouse.

"Who are you... um .. Sir," Y/n said as she stared.

"Mirio tells us about your situation and deserve a chance to prove yourself. To show you can either be a hero or a model citizen," The bear mouse explained.

"Umm, Okay," Was all she could say.

"Don't worry I'll help you all the way," Mirio smiled, as he helped her too her feet.

"I'll.. I'll do my best. Thank you Mirio," Y/n smiled as she hugged him.
