It seems I was right. Kimi was summoned to other Omniverse by Aqua when she was with the "1st Gamer (whoever he is, or was), or even before that, or after. But, it is a certain that it was before she "met" Neji. Maybe that was also planned by her. So, my idea of "Eternal Samsara" as a prequel is still possible.
