The follow-up to Fushigi Yugi.

After Miaka and Tamahome earned their happily ever after, he's suddenly summoned back inside the book and has to discard his memories in order to keep on living in the real world.
But when a power-hungry demon plans to destroy the physical containers holding his memories -which would lead to his erasure- he and Miaka need to come back again to fight this villain and protect both their worlds.

An unnecessary and repetitive extension of a series that was already repetitive.

The first two episodes brought an interesting twist concerning Tamahome's reincarnation, but it's immediately spoiled to us it was just an illusion created by a dead enemy, resurrected by this demon character who came out of nowhere. I'm genuinely disappointed. The idea that Tamahome was in actuality the reincarnation of the original series' villain would've been so damn cool.

But instead, we have to watch our bland lovers forcibly utter their goodbyes for the one millionth time and the series AGAIN presents the solution of Tamahome getting reincarnated into Miaka's world.

..Didn't we just do this? Does the absence of his memories protect him from getting erased or sent back? Obviously not, as he and Miaka get sucked into the book again, where he's immediately given part of his memories back and this becomes the new objective. The series ends with (spoilers, lol) him existing in the real world with his memories intact, making me ask the question what the point of this journey was.
I found the "you're a spirit body now, so therefore.."-excuse cheap. How does reincarnation not do the same thing? It wasn't Tamahome's actual flesh-and-blood body that got transported to Miaka's world, was it? Rather, his soul? 
So what's the difference? What does reincarnation entail in Fushigi Yugi?

The subplot where their dead friends were also given the chance to get reborn was a huge cop-out as well. How does death mean anything if people are able to get resurrected and stay chatty ghosts in the meantime.

There were a few interesting bits, but I don't think I'd recommend this to someone who watched the original. It offered too little for that.
