Quirk Boosting Drug

Fixing her hairband, Y/N looked forward at the streets as she took in the crowd that she has to walk into. Her eyes specifically scanned all the good street food vendors and restaurants that cover the area - a smile on her face. Maybe she could check this place out with Kyoka next time she is free. Or...maybe with Oikawa. Her ears turned red as she went back to thinking of their conversation the day before.

"There you go again."

Y/N looked beside her at the red-haired boy, who stared at her with curious eyes. "What?" she asked.

"Your ears are red again. You're thinking about Bakugou, aren't you?" Kirishima asked, grinning.

Although the little jab on her heart was unintended, it still made her feel a bit irritated. "No Kirishima, I don't think about him all the damn time."

"Oh yeah...you guys are having some kind of fight. Well, I'm not worried. Both of you used to fight a lot earlier too. It always turned out fine," Kirishima said but received nothing but silence in return. "So...is it the right time to ask if it's a different guy?"

"No," Y/N said, huffing and walking faster to match steps with Tamaki, who pulled down his hood towards his face. She chuckled and muttered to herself, "You are so cute."

Tamaki seemed to be a good listener as he whimpered and started walking slowly to get behind them.

"We've got idiots fighting non-stop on the streets these days," Fat Gum said biting onto his food, "Can't eat enough to keep up. Anyway, my agency was looking for a close combat type. You both are what just the doctor ordered."

"I promise I'll do my best. I really appreciate you taking me on," Kirishima said.

"If only Mirio had been around," Tamaki muttered looking down, "Man, your persistence was terrifying."

When Kirishima and Y/N went to talk to the third years, Kirishima did most of the talking. Well, he was the only one talking. Tamaki was too..reserved to answer him and decided to take in both of them. As of this moment, they were walking down the streets of Esuha City to get a sight of any fight that has been informed as been going around for a while.

"Wow, does that mean you didn't want us around?" Y/N asked in a teasing manner.

"Y/N quit teasing him, he already feels overwhelmed," Fat Gum said, "We're gonna work on those delicate nerves of yours Tamaki, then you'll be worth your way to gold."

Tamaki held his heart as if in pain and said, "Oh, your expectations only drag me down deeper. It's always like this. I swear this man scouted someone like me just so he can have someone to torment. I just wanna go home."

"Maybe he's just trying to encourage you. That's what mentors are supposed to do, right?" Kirishima said trying to reassure him.

Y/N looked to her right at the street food vendor who called Fat Gum to have some food at their place...which he respectfully declined. She already had her dinner, but...you can't just block out the delicious smell of the food right? Her mouth started watering slightly.

"I'm not like you and Mirio. Positivity is not my strong suit," Tamaki said.

"Well, that makes the two of us," Y/N said jumping ahead to walk beside Tamaki.

"Hey man, I know how it is. Sometimes when things get crazy I feel useless too. There's a gap between me and my classmates that's only getting wider. But I'm doing my best to close that gap so that I can fight beside them!" Kirishima said.

"That right there is called positivity, first year," Tamaki said and looked at Y/N, "And you are nothing like me."

"What? Just because I don't mope around all the time?" Y/N chuckled, "I know it sounds harsh but there's not exactly a detector around to detect people who are struggling. I also have a lot going on, but...hero course is my distraction from my real problems."

Tamaki whimpered, "I am so..sorry-"

"Oh my god, stop apologizing to me or I'm gonna kiss you," Y/N said.

"W-What?!" Tamaki's face turned into a deep shade of red as he started walking faster to ignore any further of her teasing. Kirishima slapped her arm lightly as she started laughing. "What? He's probably the only third year I can tease!" she said.

"They're fighting!"

They turned around in the direction from where the scream came from. A group of thieves runs from the scene of a crime but Fat Gum quickly captured four of them at once but one slipped away using his quirk. Y/N was ready to hold him using her quirk but didn't need to. He was quickly subdued by Tamaki's Quirk: Manifest, which allowed him to manifest the characteristics of any food he eats. Using octopus tentacles and a clam husk, he effortlessly knocked out the crook.

"Was that okay? It felt terrible," Tamaki immediately bent down anxiously.

"That was amazing! You've gained a fangirl in, first year~" Y/N said. Soon the crowd started cheering.

BANG!

"He's got a gun! Down!" Fat Gum said.

But it was too late.

When Y/N turned back to look in the direction where it came from, Tamaki was already hit and fell down. Gasping, she rushed forward to pick him up when she felt Kirishima pulling her arm harshly and moving her behind him.

That's when another shot was heard. Y/N held Tamaki with one arm while she held Kirishima's arm to pull him away, but stopped.

Kirishima used his quirk to harden his skin, so the bullet didn't hit him.

"That guy's mine!" Kirishima shouted looking at the guy who was currently running away from the scene.

"I'd figured that would hurt," Tamaki said.

"Wait, you're okay?! W-well are you hurt somewhere?" Y/N asked trying to help him up.

"I'm going after him!" Kirishima said and ran away to chase the villain.

And then something unusual happened. Tamaki tried to use his tentacles to grab the villain but it didn't work. Fat Gum who was on his way to help Kirishima immediately stopped and started asking him questions. Y/N's heart started feeling heavy. If one shot from this bullet made Tamaki stop using his quirk then....how would Kirishima handle a bunch of them. There was no assurance that the villain was alone. What if he was luring Kirishima away to the place where other villains are just waiting to ambush him?

"I'll go look for them!" Y/N said, running towards the direction she last saw them leave.

[ TIME SKIP ]

Hearing loud sounds of rumbling, Y/N followed the source of vibrations and sounds and ran down an alleyway. She came to a sight unfamiliar. Except for the fact that the villain didn't turn into a monster like Nomu, his quirk felt as if it was boosted. Mostly, the villain's eyes gave it away. He didn't have the same look in his eyes like he did when he ran away. To be precise, he had a crazy look in his eyes. Blades were coming out of his body and hitting the building.

Y/N quickly went towards the victims on the scene and escorted them away from the area. When he came back, Kirishima was in a whole another form - a form she has only seen him use during his training. She carefully stepped forward towards the area to look into the situation and realized something.

There's not much she can do to help if she wanted to help save the people inside the building. The villain needed to focus solely on Kirishima and any kind of distraction will make it worse. Kirishima used his quirk and moved forward to the villain as the blades started hitting him and broke into pieces. Within a few minutes, he quickly moved forward and punched the villain hard enough to knock him out.

Y/N immediately ran forward and used her quirk to hold the villain into his place - a technique she practiced during training where she used her quirk to engulf only one part of the body instead of drowning them in her water prison technique. "Are you okay?" she asked worriedly, "I'm so sorry I didn't step in! If I did-"

"Thank you," he said, and grinned at her panting, "I needed to do this on my own."

Ah.

The look in his eyes. She knew how it felt to doubt in your own abilities. She smiled, "Well, you saved the day like All Might."

The villain meanwhile started crying again when Kirishima lost his form, "Please let me go. I wanted nothing but a taste of power."

"I can't do that, you shot Suneater. But I do get how you feel," Kirishima said walking towards him, "Not long ago I-"

"No one cares about your sob story wannabe," the villain said and in a second, he used his quirk again to boost himself forward and started rushing towards the exit to escape. He hit Y/N away using his hand and pushed her away on the way.

"Oh, no you just didn't!" Y/N shouted and pulled him to hit a nearby wall with the quirk she used to hold his leg. The villain wasn't fazed as he used his quirk to jump off the wall and started using his blades in her direction, making her lose the hold on his leg.

But, he wasn't prepared. As all the blades started melting down due to the high temperature, she slowly started walking towards him with a sneer on her face. "You don't want me to hit you with this water now do you?"

The villain visibly started sweating when he decided to use his quirk and make an attempt for an escape. Y/N quickly used her quirk as whiplash and hit his back, making him fall on the ground. "Shit, my temperature is still a bit high," she said, "It won't...leave a mark right? I won't...get in trouble...right?" She watched as the villain squirmed on the ground in pain when Fat Gum arrived.

"No, you won't. You guys did great! Always remember, the key is how fast you can make the villain lose the will to fight," Fat Gum said.

After a whole half-an-hour of Y/N and Kirishima receiving praises for their spectacular debut, both of them regrouped with Tamaki and Fat Gum near a bridge and filled in the details.

"His quirk fired up, huh?" Fat Gum said, "Power boosting drugs are banned in Japan. Didn't last long so the bullet was probably a black market version. The ones from the US work at least an hour."

"Wow, you know a lot about this stuff," Kirishima said.

"Yeah I used to work with the cops to catch drug smugglers back in the day," Fat Gum said. He turned to look at a police officer who came by to inform him about the bullets and started talking with him.

"So how are you holding up?" Y/N asked Tamaki.

"To take your quirk away like that. It's a nightmare for a hero," Kirishima said.

"That's not all. You protected me back there. You're just like Mirio. You shine so brightly, just like the sun," Tamaki said hiding his face under his hood.

"You're the same way. I wouldn't even be here if you hadn't gotten me this work-study," Kirishima tried to assure him.

"Here we go again. So much positivity," Tamaki said.

"Hey, we mean it. You're actually really good and managed to catch the one getting away alone," Y/N said as a small evil smile took over her face, "You mope any longer and I'm gonna kiss you~"

"God you're so cringy," Kirishima said as Tamaki's face turned red once again and he faced away from them.

"Well, I wasn't trying to look cool," Y/N retorted.

Finally done with his conversation, Fat Gum turned towards the trainees and said, "We'll stop by the agency and then step by the hospital so all of you can get checked out. There's a couple of things I wanna look into as well."

As they started walking towards the main road, Y/N groaned holding her chest.

"Wait I thought he just pushed you. I mean you melt the blades down right?" Kirishima asked.

"God Kirishima," Y/N blushed and looked forward at Fat Gum's back who was walking in front of them, "at least observe before you speak."

"What?"

Feeling irritated, she pinched his arm and said, "I'm holding my chest for a reason, you idiot. He hit my boob!"

"Ah..." Kirishima tried to come up with an excuse awkwardly and apologized instead, failing to come up with one.

"Whatever," she said, cheeks flushed as she rushed forward to walk beside Fat Gum.

Kirishima sighed in relief and whispered to himself, "Thank god Bakugou isn't here."
