How does the fushigi yugi series end?

Miaka uses her last wish to put Tokyo back to normal, even though she loses Tamahome. Miaka is rejected from Jonan, but accepted at Yotsubadai, with Yui!

When Keiske picks her up from school he introduces a new student at his school...it's Tamahome!

However this Tamahome can't remember what happens inside the universe of the four gods, and he goes by the name of Taka.

In the final volumes (Part 2) the celestial warriors try to collect the beads of Taka's memories of the other celestial warriors, and of Miaka.
