The new character that appears in this book is Tai Yi-Jun. She gave the Universe of the Four Gods to Hotohori. She is pretty scary if you're not used to her.
In this installment, Miaka, Tamahome, Hotohori, and Nuriko go to see Tai Yi-Jun. At the beginning of the book, Miaka doesn't feel well. Nuriko believes that if she goes back to her hometown, she will feel better. So the foursome go to Daichi Mountain to see Tai, who could help Miaka. However, there is one test needed so Miaka can prove if she really is the Priestess of Suzuku. It involves... Miaka's bad side?! Oh no!! No way I am telling you anymore than that, but I will tell you that Miaka succeeds in going back to her hometown.
The second entry in Watase's manga series continues the story from the first book. Miaka is still discovering her place in the China of two millenia ago, while her best friend, mother, and brother are searching for her in the present-day world. Miaka, however, has more pressing problems; Hotohori has decreed that Miaka and the three celestial warriors already uncovered need to make a pilgrimage to the sacred mountain to find out more about where to look for the four celestial warriors not yet uncovered. Which, of course, exposes everyone to all sorts of danger.
Oracle, like the first book in the series, is quickly engaging, with likable protagonists, amusing situations, and some unexpected turns. It does have a bit of the confusion factor of some other manga (sometimes it's a bit hard to tell some characters apart, thanks mostly to hair color being variable from frame to frame), but it's kept to a minimum here. Fushigi Yugi is good stuff. *** ½
If you are looking for a new manga series to read, this could be the one you want. There is action, comedy, several possible tangles from 2 love triangles. It does have the tried and true story of a girl thrown into a distant time/land and struggles to find her footing. But, I feel the humor, the heart, and her art that Yuu Watase brings to her stories elevates her books above many writers. You will not find graphic violence or graphic sexual situations. There are many other reviewers to give you the complete outline of the story, so read those and see if this series will "fit" you.
