QUESTION

So this post is different because rather than reviewing a manga or anime, I would like to ask about them. There is a series I've been wanting to read called Fushigi Yugi by Yuu Watase (it's 18 volumes and has an anime). After Yuu-sensei finished Fushigi Yugi, she wrote the PREQUEL, called Fushigi Yugi: Genbu Kaiden. I'm wondering if I sould read the prequel first for obvious reasons, or if I should read the the original first because the prequel may have references to it or somehting. If you have a suggestion or a review for this series (NO SPOILERS PLEASE), then I'd love if you'd leave a comment :D
