Fushigi Yugi OVA: Dai Ni Bu

Tamahome is gone -- but not forgotten. He has been reincarnated as a man named Taka in Miaka's homeworld, and as fate would have it, they have met each other yet again. The memories of Tamahome's past and love for Miaka remain intact, but are trapped within memory globes in the Universe of the Four Gods. It's up to Miaka, Taka, and the rest of the old gang to find Taka's memories and help their homeland once more!
