Just finished watching this last night. I overall really liked it, but I was slightly disappointed with the ending, I felt like it was slightly incomplete. So I might read the manga. Maybe.
Story 8/10
Decent. At first I was a little alarmed by the similarities it drew to Saint Tail, but meh, whatever. I liked it enough, so yeah. Whatever.
Main=Thief=reincarnation of Jeanne d'Arc (I'm assuming Joan of Arc)
Romance: Absolutely there. Wished there were more episodes to fully showcase it. Typical good girl/bad boy.
Art 6/10
Slightly displeasing to my eye, because I'm not a huge fan of when the eyes are overly big, but meh, didn't bother me too much after a few episodes.
Sound 7/10
Pretty good. I just didn't really like how some of the music was really random and out of context. Why, WHY would you use Beethoven's beautiful Moonlight Sonata for evil? But overall, good. I liked the first opening theme. Nothing that special though.
Character 8/10
Okay, relatable. Some were slightly annoying, but hey, this is a shoujo genre. That can't be avoided really.
Enjoyment 9/10
I did enjoy it, so yeah. 9 is a pretty good score for this.
Overall 8/10
Kind of like your typical shoujo story, with a few unique characters. It wasn't particularly special to me though.
(Sorry for the extremely short review, was rushed)
