The series as a whole I give a solid 4. It is fun and has supernatural stuff which I am a big sucker for. This one volume ges a three because, althought they start taking things more seriously action wise, I think there is far too much emphasis on other characters. In my opinion the events are unnecessary to the main couple's progession. That and it kinda scared me a little when the main kid gets attacked. Yes, the stars in my rating system are based on fan-service and moe!
