Fushigi Yûgi (Canon, Manga, The Universe)/Hacklar

Summary
Fushigi Yûgi is a Japanese shōjo manga  series written and illustrated by Yuu_Watase, which was also adapted as an Anime in the 1990s.

It features 15 years old student Miaka Yuki, who is warped into another world when she opens a magical book named " The_Universe_of_the_Four_Gods ".

The story features plenty of romance, fantasy, magic, humor and - at least when compared to many other shojo manga -  a lot of action and fight scenes between characters with superhuman and supernatural powers.
