This, my dear community, is proof I was damaged in the confined solitude of the quarantine.
Unlike in AO3 however, I'm keeping this a one shot so your brains don't melt from sheer stupidity. And as long as nobody asks me to post the rest, we should be fine!
Anyway... Let's go into the madness.
Izuka Midoriya wasn't sure what to make of what was happening right now.
She understood most of what had just happened: her childhood friend-turned asshole-turned bully, Natsuki Bakugou, demeaned her for being Quirkless, useless, calling her "Deku" to make it clear, then dropping her lunch box when she refused to share.
She honestly couldn't think of a genuine reason why she needed to share it with her of all people: her parents were rich, surely they could give her money to buy her own lunch, but she digressed.
The part she had trouble processing was that she was currently moving her hands in a pulling manner, and the lunch box was heading back to her with what little food had been saved.
"What's going on?" was all she could muster by the time the lunch box sat on her lap.
And then Bakugou grabbed her and lifted her by the neck of her dress.
"What the hell did you do, Deku!?" she hissed. "Didn't you say you were Quirkless!?"
"T-The doctor said I presented the n-normal bone structure for a person with a Quirk," Midoriya explained. "E-Everybody just assumed I was Quirkless-"
"Don't fuck with me, Deku!" Bakugou snapped, slamming the girl against the wall. "You knew you had a Quirk all this time, didn't you!?"
"N-N-No! I'm just as surprised as you are!"
Just as Bakugou gritted her teeth and got ready to get violent, a purple ball hit the back of her head, and the explosive blonde dropped Midoriya and scanned for the source of the ball, with little success.
Midoriya, meanwhile, ran for her life and hid at her classroom, sitting on her desk as she caught her breath. She clutched her chest and rubbed her forehead, utterly perplexed at what just happened.
She was pretty certain she had just used her mother's Quirk: if not the original Quirk, then a variation of it.
But there had been several times when she made the same gestures, and nothing had happened. What was different about today?
"Are you okay?"
Midoriya turned around, and saw a miniature male student entering the classroom, with a row of purple balls for hair?
"Yeah, I'm fine," Midoriya tilted her head. "Are you the one who helped me just now?"
"Yeah, I threw my balls at your friend while she wasn't looking," the boy casually answered. "My hair balls, I mean. I don't know if you're one of those people who put their head in the gutter, but I didn't mean anything weird-"
"I know, I get it, don't worry," Midoriya smiled. "Thanks for helping me... um..."
"Minoru Mineta."
"Oh hey, I've heard about you! You're the pervert from Class 3-D, right?"
"3-C, actually: I got some friends from 3-D, though, maybe that's where the misconception came from."
"Well, okay, you helped me, so I'll give you a chance," Midoriya scratched her chin. "I got more important things to focus on, anyway, like what I just did."
"Your Quirk, right?" Mineta asked.
"Yeah, but I've done the same gestures other times Natsuki dropped my lunch, and nothing happened," Midoriya hummed. "I know I have a Quirk, but to have it be unleashed just now..."
"Maybe it needed some kind of trigger?"
"Well it can't be fear, 'cause I feel it every day," Midoriya tilted her head. "Maybe shock?"
Suddenly, the bell rang.
"Well, I'll have to think about it later," Midoriya sighed. "Thanks again for the help, Mine-"
But when she turned around, Mineta wasn't at the door, but getting ready to jump down a window.
"If they see you with me, you'll never hear the end of it," was all Mineta said before jumping down.
And, judging by the sounds, he fell on top of a bush. But regardless, she got up and walked to her classroom.
Once classes were done and she was back home, Midoriya hit the couch and took a deep breath as her mother approached her.
"Good evening, Izuka. How was school?"
"The usual, except for one thing," Midoriya got up. "So, Natsuki was bothering me again when something happened and I dropped my lunch."
Mrs. Midoriya's unamused expression quickly got through Midoriya's lies.
"Okay, she bullied me and dropped my lunch box. But, just as it fell, I did the gestures I usually do... and the lunch box stopped in place and levitated towards me."
"Like my Quirk?" her mother asked.
"Yeah, but this is the first time this has happened," Midoriya sighed. "Do you have any idea why?"
"Well, I'm gonna need to see you use the Quirk before I can say anything, but why don't you take a bath first, sweetie?" Mrs. Midoriya replied. "You just had a long day at school, I believe."
"Yeah, maybe that'll help me clear my mind. I'm gonna do that."
One bath later, Midoriya quickly put on some casual clothes and returned to the living room, where Mrs. Midoriya had set up a couple of things for Quirk practice.
"Oh, Izuka, before we begin, I gotta ask," Mrs. Midoriya took a deep breath. "Why did I find my panties in your clothes?"
"I was in a hurry and didn't notice what panties I was grabbing, I guess," Midoriya answered as she walked to the table. "Anyway, this is what I did."
She made the gestures... and nothing happened.
"Wait, let me try again."
She tried again... same result.
"What's going on?!"
"Wait," Mrs. Midoriya remarked. "Let me go get something."
The miniature woman went to her room, and quickly returned... with a pair of panties on her hands.
"Try these on."
"... Mom, care to explain?"
"Well, I just got the idea that maybe your Quirk requires something specific to work, like for example, underwear," Mrs. Midoriya handed the panties to her daughter. "You wore my panties when you used your Quirk, maybe you can only use them while wearing them?"
Midoriya eyed her mother like she was insane, but decided to humor her: she took off her current pair of underwear, put her mother's underwear, and executed the gestures again.
This time, the objects reacted and levitated towards Midoriya. And as the girl's eyes widened in disbelief, her mother folded her arms and proudly said:
"I believe that proves my hypothesis."
Quirk: Panty Powerhouse! By wearing the panties of a person with a Quirk, the user can replicate that same Quirk, as long as it's not a Mutant or Transformation type Quirk.
