“Then I guess I should start by explaining the Seyla. I’m sure you already know, but we’re also infected.”

“I heard that infection makes you immortal,” Yogiri said. There were plenty of people who would wish for that, but from what they had heard so far, there seemed to be some negative side effects.

“Technically, we can’t die or grow older. Once you’re infected, you don’t age anymore. It may sound odd coming from someone who looks like a child, but I’ve been this way for decades already.”

“Just how immortal are you?” Yogiri asked.

“As far as we can tell, there are no limits.”

“Even if your body is ripped apart?”

“Put the pieces back together, and we’ll go back to normal.”

“What if you’re eaten by an animal?”

“The lost pieces will regenerate.”

“And if you’re burned up?”

“We’ll just reappear from the ashes.”

“What if you’re dissolved in acid? Oh, I guess that’s probably the same as using fire.”

“Yes. We’d still go back to normal.”

“But if you jumped into a pool of acid, you would keep dissolving even if you regenerated, so that’s almost like dying, right?”

“Takatou...you’re starting to sound awfully brutal,” Tomochika interjected.

“We tried that,” Scott answered. “We couldn’t get a pool of acid, but we did try jumping into a volcano. The lava was enough to keep killing us, but I’m still here.”

“Why is that?”

“If you leave someone infected dying over and over like that, eventually they’ll reappear in a safe place.”

“So...it’s not really just about regenerating the body, then.”

“Right. We tried lots of things, like sinking to the bottom of the sea and cutting our bodies into many pieces, sealing them in concrete, and scattering them, but in any situation where we can’t regenerate, we just reappear with an entirely new body somewhere else.”

“Even if you’re petrified or frozen?”

“Yes, the same thing happens. And I can tell you, it is a weird feeling to suddenly appear next to your own petrified body.”

“Hmm. What about locking yourself in a cramped box until you go insane? That could be a spiritual death of sorts.”

“You’re a bit too into this, aren’t you, Takatou?” Tomochika said with a sigh.

Yogiri couldn’t disagree.

“We tried that, of course,” the boy said. “Losing touch with reality might be good enough in the end, after all. But it was no use. Mental damage is regenerated by the Seyla as well. Eventually, we will appear outside the box, fully restored. We can even remember going insane, but can’t keep ourselves that way.”

“That’s amazing. It’s like the Seyla has thought of everything.”

“Doesn’t that make you curious, though? We do not get sick or old, and no matter what danger we face, we always return to life somewhere safe. That’s a pretty good deal, don’t you think? So why would people like us want to die?”
