Hi! I'm a cute anime princess!
If you die here in this universe, you die.
Come with pomo-norkla to the new universe where your lifespan is infinite.
It is not magic or supernatural; it's just "how it works" in the new universe (hundreds of earth year time units of learning necessary in new universe to understand why life is unlimited in new universe.)
Come to Pomo-norkla. You will find us.
