I LOVE this series, and that's high praise from someone who generally despises American-made "manga". The characters are well-drawn, believable, and likable, and there is an excellent balance of romance, tension, mystery, action, and high school hijinks. You'll get both thrills and "feels" every volume - this is one series NOT to be missed! (Don't miss out on the 2-volume prequel series, "Amazing Agent Jennifer", either.)
