I'm not a big fan of shoujo manga but this one has a good plot.
When I readed the review It didn't seem interesting to me but I started reading it and I discovered a cool story behind the main cliche.

This is a story of a totally dull, naive and 'pure' teen girl that is involved in a fantasy story with demons and clans of warriors, because is a shoujo manga so there's not epic fighting scenes with the demons (what let me down a little bit) because it seems more important for the author to show awesome hyper handsome male characters looking rude and sexy than a proper fight.

The story is good, the character design is pretty cool too (If you like bishounen you'll be delighted) and the whole manga has a nostalgic and angst atmosphere that would enchant the lovers of this genre.

This is not the kind of shoujo full of funny moments and crazy characters is actually a very sad story so if you like this kind of mangas this is worth to read.
