A/N: So here's the first part of how ever many parts in my series of manga-focused Arc V fanfics.

I have to admit, I latched weirdly onto the manga version of Arc V. I love the relationships between the Yuu's, and it resonated a lot within me. I'd like to expand a lot on that.

If he were to be perfectly honest, Yuya would've had to say that he wasn't much of a quiet guy.

Yes, he was something of a loner, but that sort of title more fit Yuto than him. He was an entertainer, after all, and actually liked being around people. Just because he'd been cut off from most socialization, it wasn't as if he was ever really alone. All things considered, Yuya was entirely extroverted.

That being said, he still wished that he could get some peace and quiet these days.

When he wasn't being confronted by those who wanted to meet and duel the Phantom, his ear was being talked off by his new manager. And when she wasn't trying to get all the information she possibly could out of him, monitoring the city and keeping himself properly hidden to look for the card he needed took enough effort to keep him more than occupied.

Of course, even that wasn't too bad. He'd been dealing with most of that for years.

What he hadn't dealt with in years had to do with two of his others making their reappearance.

Ever since Yugo and Yuri had come back, he'd been getting these sudden spikes of pain in his head. They happened when he was younger, back when he had particular trouble dealing with three other personalities all living in his brain, but he eventually got used to them.

He was starting to truly realize just how quiet Yuto was, at least in comparison to the other two. He might have talked a lot, sure, but he tended to keep his comments short and to the point, and generally avoided yelling or overreacting to situations. There were some exceptions, but Yuya was definitely the more outgoing of the two. All in all, Yuto was fairly grounded, and understood how to allow silent moments.

Yuri and Yugo...didn't. Not usually, anyway.

It wasn't much of a surprise that Yugo was the worse of the two, but when together, it was sometimes difficult to tell. While all four of them cared about each other, Yuya found that he was much closer to Yuto, and that Yuri and Yugo had formed a much stronger bond than the ones he'd had with either of them.

That didn't stop the two from arguing all the time, though.

And that was probably the issue, though he couldn't quite make out what they were saying.

Sitting on the couch of their hideout, he took a glance at Yuto's collected form, no sign of pain or discomfort, and wondered how, but knew that the dark-haired boy was probably a lot more used to this than he was. And, of course...

Yuya held a hand up to rub at his face and stared at his transparent other. "Why do we have a headache?"

Though he said we, he in reality meant to refer specifically to himself. He'd gotten so used to looking at himself in the plural form, even when it didn't totally fit. Physical pain only affected the one in control of their body at the time, and this evidently included their frequent migraines. It was one of the main reasons that the others were perfectly fine letting Yuya take the reigns for the majority of the time.

They cared about his well-being, yes, but they knew well enough that pain inflicted to the body was inevitably going to affect someone. If Yuya wanted to be the one to take the brunt of that, it wasn't as if they were going to object, for the most part.

Crossing his arms, Yuto cocked his head to the side. "Yuri and Yugo are arguing about which of us would represent which of the Four Horsemen."

"What?" the tangible boy responded, removing his palm from his cheek. That seemed a little ridiculous, even for the two of them. "Like, of the apocalypse? Why?"

Yuto only shrugged, taking a step back from his other. "I couldn't tell you. Yuri told me that he would be Death."

Shaking his head, Yuya snorted. "With the way you both dress?" he replied jokingly. The dark-haired boy looked down at himself, uncrossing his arms and looking incredulous, as Yuya continued. "You'd be Death. Yuri would be War, without a doubt."

"You think that?"

"I know that!" Yuya exclaimed as he moved to lay down on the couch. He waved a finger in the air and said in a matter-of-fact tone, "Yuri's been the one picking fights with people ever since we were kids. I mean, remember the last time we tried to attend school? He almost sent someone to the hospital, just for trying to steal one of my cards!"

The dark-haired boy shrugged and looked away, muttering to himself, "It was an important card," he raised his voice and narrowed his eyes onto Yuya. "That, and he was threatening you. You know that Yuri would never tolerate someone talking about hurting you, even if their words are empty."

Oh, did Yuya know that. He sighed and folded his hands behind his head, shifting his gaze to the ceiling.

It was probably wrong that Yuya found the borderline unhealthy possessive nature endearing and heartwarming, but that behavior was simply Yuri. All their lives, Yuri was like that, and it was always for the sake of Yuya's safety, and always worked out in their favour. Maybe it was because they'd known each other for so long, or because they shared a body and a headspace, but he couldn't think of Yuri and find his aggressive protectiveness anything but admirable.

Well, that wasn't entirely true. Yuri could be a little harsh at times. Still, it was hard for him to mind too much.

As the pointless war raged on, he knew well enough that another would spark right after. And after that, yet another. Yuya couldn't find it in his heart to blame them and, after letting out a sigh, he closed his eyes. What else were they all to do, anyway, but talk among themselves?

All the four of them ever really had was each other.
