Your guess is as good as mine. I'd liken our arrival to a space-time technique but I can't say I remember how it happened nor have I ever heard of one on this scale.

[Not to mention that ninjutsu wasn't exactly something anyone here was capable of, but it was the best comparison he could make really.

Did the ninjas even have knowledge of different planets? \o_o/]

There are people here from many different worlds, the natives aren't very forthcoming as to how or why we were all brought here. Unfortunately I can't offer much of a briefing.

Though if it is an illusion... well. We don't exactly have a way to disrupt it, currently.

[Of all people he's fairly sure a Hyuuga would immediately notice the suppression of their chakra.]
