Haha, I feel so girlish when writing this review.
As other have said, this is a very refreshing manga that I love to read when I just want to relax. It is also really cute.

Story: 8
Well, it's pretty much about Mana, a exorcist who transfers to a school to get rid of a vampire, but to her surprise... he is really laid back. This boy is Okamoto. I for one thought the story was cute, despite lacking some excitement. And despite the story being very relaxing, it does have a plot that is very funny, sweet and still a little exciting. Of course there are serious moments that get you all excited. I enjoyed the story because of that.

Art: 8
The art was really cute and the chibis were super sweet. Despite the art being nice and all, it was not that special that really made me say wow, but it was still very good. There are some things I don't like that much, but it's only small things and details.

Character: 9
I really loved the characters in this manga. The main girl had a personality that was funnier than usual shoujo manga main girls have, but she still has that little shyness. The boys are hilarious, especially Okamoto with his little comments and such. The characters in this manga really are awesome, but others do need a little fixing. Some lack a teensy bit personality, but other than that the characters are great.

Enjoyment: 8
This manga doesn't get me jumping on the couch when it updates or anything, but it's more of the manga that makes you smile and laugh when reading. I for one really think this a enjoyable manga that is fun to read and definitely something not only girls should read.

Overall: 8
Overall this manga is a cute, romantic, but hilarious manga that I recommend BIG-TIME.
