All For Her (BNHA/MHA OC)

Power Trip

Akihito Shigaraki.

A name that, years from now, was to be forgotten in exchange for All For One. Right now, though? Right now, he's focused on surviving college. Really, did he have to go into quirk studies? Oh, right, Yoichi practically shoved him into it.

So, here he was, walking through the dorms at.... One in the morning? Yeah. He was already a lofty twenty years old. Surely he could get his sleep schedule on track, right?

Which, of course, is when he spots his greatest rival-

"Shigaraki." The young woman greeted.

"Raimei." He greeted back, brows furrowing at the sight of her sipping coffee.

He began making himself a cup, yawning.

"Can't sleep?" The girl asked.

He glanced over, crimson red meeting hot pink as they locked eyes. He watched as she brushed a lock of magenta hair behind her ear, feeling his mind race with possibilities.

"Nope," He finally responded. "Can't catch a wink. Probably due to stress."

"You want drugs?"

Akihito nearly choked on air as he whirled around to face her.

"I- what?"

"Drugs." She repeated. "I get some horrible insomnia sometimes, so...."

Akihito considers it for a minute. On one hand, he could probably just go and steal- er, borrow a stamina quirk, but where's the fun in that? Also, he has exams in the morning.

"Okay." He finally said.

"Alright."

Once she walked away, he began to think. He didn't really have many interactions with Raimei. The two were more so classmates than friends, truly. The two rivaled each other in nearly everything. Quirk studies, tactics, planning....

"Here."

Akihito turned, grabbing the medicine from her. He popped a few of the pills into his mouth, shuddering at the taste.

"...."

"...."

Both were quiet for a moment. Akihito then stared at her, assessing her for a moment.

"Why are you up?" He finally asked.

The young woman sighed, looking away for a second.

".... You can't tell anyone."

Oh. Why would she-

Suddenly, she clenched her fist her muscles appearing to bulge slightly, inky dark pink energy coiling around her fingers.

"You have a quirk." He murmered. He then grinned, repeating "You have a quirk!"

"N- not so loud!"

"Oh! Oh my days! Finally! I can finally talk to someone who- just look!"

He let his hand open, electricity crackling on it, switching to a few flames.

"You.... You have a quirk too?!"

.

A few days ago, Yuzuki would've been horrified at the thought of using her quirk like how she wanted. She hadn't really had any friends, and quirks were still rather.... Frowned upon.

So, she didn't expect to be laying in Akihito's dorm room, working on old homework. Gods, she hated English.

"Why the fuck is this a requirement?!" She hissed, looking annoyed.

Akihito, who was sitting at a desk in his room, glanced over at her with a smug look.

"Angry?"

"Very!"

He chuckled, saying "It's just how things are."

Yuzuki sighed, letting her pencil fall.

".... So.... What's your quirk?" She finally asked.

Akihito grinned. He practically jumped out of his seat, placing his hands on his hips, puffing out his chest.

"I call it.... All For One!" He said proudly.

.... A snort made him falter. Yuzuki burst into laughs, holding her stomach as she wheezed and giggled, the sound filtering through the room.

"Wh- stop laughing!" Akihito said, clearly embarrassed. "All For One is a perfect name!

"A- All For One? That's what you chose?" She snickered. "Sounds like then name of some cheesy movie! Really, you should pick something else...."

"Hey, I'll have you know that All For One is a name that strikes terror into the hearts of its enemies!" Akihito insisted. "Just wait! I'll gain hundreds of followers, and people will treat me with respect!"

Yuzuki rolled her eyes. Yeah, right. Like she'd pay respect to the name All For One.

"What about you?" He then questioned.

"Hm? Oh. I call my quirk...."

She paused for dramatic effect before smirking.

"Full Throttle!"

".... That's worse than mine."

"Fuck you!" She growled. "Plus, it's not the only one I have...."

"What is it?" He asked.

Yuzuki hesitated, before responding "Emergency Medic."

Akihito squinted at the name. A healing quirk, perhaps? He gestured for her to continue, greatly wanting details.

"Basically, I can help you recover from severely damaging or life-threatening injuries." She explained. "Meanwhile, Full Throttle lets me get super strong and powerful. What about All For One?"

Akihito shrugged, saying "I can take and give quirks."

She stared at him.

"Bullshit." She mumbled.

That day, the two learned much about their quirks.

*Later on....*

It's now been three weeks since the two had started to bond.

"You sure it's fine for me to come over?" Yuzuki asked.

"Of course! You and my.... Subordinates will likely get along! And I think Yoichi will like you!"

The two soon arrived at the house of All For One. Honestly, Yuzuki expected him to live somewhere more.... Glamorous. She noticed a rather skinny man standing by the front door, raising an eyebrow at him.

"Hello...?" She hesitantly said, waving at him.

"Yoichi, this is my friend, Yuzuki. Yuzuki, this is my little brother, Yoichi."

Yoichi and her locked eyes. The boy proceeded to look her up and down.

".... Is he-"

"Ah," He suddenly said. A shit eating grin popped onto his face, and he said "So, you must be the 'mistress of All For One'."

Yuzuki's face went red, her body going rigid. Akihito's eyes comically widened, the man flashing a glare as he chastised his younger sibling (who was still being a smug little shit).

What did she just involve herself into?
