Yuzuki barely has time to duck underneath the attack going for her as she dodges. Since when did being with Akihito involve being a damn target?

"All For One!" She shouted, crouching down.

She felt the familiar pull of Summon, before dropping down in front of her boyfriend, far away from her attackers. She shuddered, still unused to how the black and grey goo felt.

"Sorry!" Akihito said, grimacing. "I'm still getting user to using that quirk.... That's actually why I'm glad you had me use Summon."

Yuzuki raised an eyebrow, glancing at him. What was he on about?

"I want to give you a quirk!" He said, grinning.

"Oh." She said. "Wait, why?"

"It's a simple anti-aging quirk." He explained. "One for me, and one for you. This way, we can keep living!"

Yuzuki stared at him.

".... I'll stop aging."

"Yes! Isn't that-"

"Exactly!" She snapped. "I'll completely outlive everyone I care about! All my friends- and what about Shoko?! Do you have any idea how crazy it's going to be to spend time around her when she's fifty while I still look half her age?!"

"W- well-"

Akihito felt the words die in his throat. He'd never seen Yuzuki's quirk often, usually only when needed. Yes, of course, he'd seen it curl around her fists when she was fighting, and of course, he'd witnessed it on her off days. Never when she was angry. Never out of rage.

This was different.

A pink so dark it was nearly black, and rage so powerful it could level his own. Yuzuki's quirk flushed across her body, encasing her in the powerful energy that was Full Throttle. It was.... Suffocating. Don't get him wrong, he'd been scared before, but this? Now, he knew what it was like to be on the other end of someone's unbridled rage.

Before he could even choke a word out, Yuzuki turned around, walking right back out.

.

"Do you know how dead to me you are?" Shoko hissed at him, letting the man into her home.

"Evening, Shoko." Akihito said nervously (and desperately). "You look wonderful! Has anyone ever told you that you're glowing?"

Smoke wisped from her palms, her quirk simmering.

"Akihito." She ground out. "I am five months pregnant. This little demon doesn't give me a moment of peace. My feet hurt. There better be a good damn reason you're here while I'm on maternity leave."

Akihito took a step back.

"I pissed off my girlfriend. If you help me, I will use a relaxation quirk on you."

Shoko's mood flipped in an instant. Akihito took that as a sign to sit down, a sigh leaving him.

"Alright, what dumb shit did you do this time?" She questioned.

"I offered her an anti-aging quirk."

Shoko's face hardened.

"Boss." She growled, smoke crackling from her palms.

"Yeah, yeah, I know. Not a very bright idea on my part." Akihito admitted. "I just.... It was always in my plans as the 'demon lord' to live for ages. I never had a reason to change them. I didn't want to change them. Now, with Yuzuki-"

"You can't decide." Shoko finished for him. "You spent so long on this one plan of yours, but you love her more."

And that was just it, wasn't it? Yuzuki wasn't just another person, she was his. She'd been looked with him since the beginning, and he....

"I love her." He choked out. "I love her more than I love anything in my life. I wouldn't ever force a quirk onto her, I just.... I'm terrified."

"Love makes you do crazy things." Shoko chuckled. "Tell me this: does she know how much you love her?"

Akihito blanked.

".... That's sad."

"Fuck off!"

*Later....*

Yuzuki angrily went through books, Full Throttle increasing the speed of each movement. Akihito eventually peeked into her personal library, grimacing at her expression.

"Hey, love." He said slowly.

"Hey, bitch." She snarled in response.

He tried not to wince.

"So,  I must admit, I didn't.... I wasn't thinking when I made my very poor suggestion-"

"Akihito," Yuzuki cut him off, turning to him. "Stop it. Stop filtering yourself."

He threw his hands up, saying "How could you say no?! I mean, people have wanted to be immortal for years! You don't have to get old, and sad, and you never again have to worry about aging! How could you refuse such an offer?"

Yuzuki crossed her arms.

"Which is.... Why I went to Shoko." Akihito breathed out. "She verbally slapped some sense into me. Look, I know I'm not the.... Most amazing partner, but I'm trying. Every relationship has its arguments, and I want us to be on the same page. So, if being the demon lord while being your boyfriend means I have to somehow live for ages without a quirk to assist, then I.... I'll do that. I would rather live one hundred years and be a frail, grumpy old man, than live them without you."

Yuzuki scanned his face for any trace of a lie. Finding none, she sighed, letting her arms drop to her sides.

"I know.... So, come on."

"Huh?"

"Gimme the quirk you big dumb idiot."

Akihito felt the air in his lungs vanish for a few moments.

"However, I have conditions." Yuzuki said. "First off, I want to wait until I'm twenty-five to take it. Number two, since my body can handle multiple quirks, I want access to whatever quirk I want. And lastly.... If we're making this official, there are some things I want to sort out."

"Name it, my love." Akihito said, taking her hand.

Yuzuki nodded slowly.

"I want to kill my parents."

The look on his face must've been something else, because she immediately started laughing at him.
