A demon servant fueled by kisses, sounds pretty uninteresting no? From the summary, I didn't expect much from this series. I was pleasantly surprised, this manga is very good!

Story: (8)
In the first few volumes, the story doesn't seem to have much plot aside from accomplishing the romantic relationship there is. The first volumes are almost episodic, each mini-arc teaching you a little bit more about the characters and the situation they are in. Around the middle of series, you are shown that this series really DOES have a main plot. From that point on, the story goes by relatively fast and gives you plenty of plot twists. A few details of the main conflict were very typical of manga with "princesses" and really annoyed me. Not only that, aside from a few plot twists, the end of the manga is pretty predictable. The end is still lovely, filled with fluff and your "happily ever after" type of mood. Story only get an 8 because of the irritating details and predictability of the last few volumes.

Art: (10)
From the start of the series, I have to say I fell in love with the art. It's wonderful and extremely attracting to the eye. I wouldn't be surprised if someone drooled over one of the pages. Nearly every character is handsome/pretty and has a unique look when comparing with the other characters.

Character: (9)
Characters were amazing, even if a few of them held many characteristics over-used in manga. Since the first few volumes were dedicated nearly entirely to the characters, they had fairly good development. Each character had a unique personality when compared to the rest of the cast, even if quite a few shared some traits as well. The cast isn't even really that big, so there was a good amount of time to develop most of the characters. They're all really lovable and end up messing with your feelings throughout the series as good and bad things happen to them.

Enjoyment: (9)
I really enjoyed this series. It really surpassed my expectations with its good characterization, excellent art, and good story. I read this manga fairly fast, only taking a break to wait for the last two chapters to be scanned.

Overall: (9)
What can I say? Good characters, wonderful art, good story, and a nice handful of plot twists; this is a really good series. Don't let the summary fool you, it really drives your expectations down, when this series is actually great. If you like a bit of dramatic romance(Somewhat forbidden), friendships, and surprising plot twists in a manga this one would be a good choice! :)
