“Woah, that’s a big wall of text!”
Pandora-Kid might have lost interest there.
“Maybe breathe once in awhile so you don’t pass out in front of me. Handler wants to ask if you can break up those walls so she can follow better! Her brain has trouble reading biiiig paragraphs.”
(Hush, you.)
“So… you’re saying there’s more than one Pandora, and it’s ripping up the universes?”

“Ah… sorry.” Tends to get out of hand with rambling when a train of though catches hold.
“That’s basically it, yeah. Though, not ripping in any ‘end of the world’ type of way, just enough for some interactions to keep the chain of potential immortals going.
Think of it like how you have infinite lives in some video games, but where you have to reset to a certain point because of it. Except, instead of one person having all those lives, it’s spread infinitely though the universes. Doesn’t do much for them separately, but if they can interact with each other, the collective ‘Kaitos’ could, say, have two or three ‘lives’ in one universe.
It wouldn’t care about the individuals though, so it’d be the death of one, but if there’s more than one Kaito in the universe that happened in, then to the world, he never died. One is dead, but there’s still an existence.
Finding and using Pandora increases the resistance to death for each individual Kaito, making it even harder to get rid of all of them, and thus, granting a sort of ‘immortality’ to us.
…But that might also mean that if we all destroyed the Pandoras, then the holes would close and we wouldn’t be able to see our other selves again. …So while what you did might not have been the best of plans, situations like that might at least let us continue talking like this. It just also makes it harder to entirely get rid of the problem of people looking for it.”
