Check out the anime series, Now and Then, Here and There.

It combines both the elements of immortality (the main female is over 600,000 years old) and the end of the world (the sun has just recently entered its red giant phase)

It takes place several trillion years in the future, were the earth is basically a total desert and with only one hidden village having a true water source.
