It's a really lovely manga - the art is tranquil, detailed, fluid and elegant. The main character of Yuuko Ichihara is very lilkable, as she is a strong female lead with plenty of enough complexity. The rest of the characters also follow a comprehensive journey and characterizations, and the overall stories that follow are authentic, mysterious and original. You also really get true questions on the daily aspects of life and morality.
And yes, there is a healthy hint of good quality comedy.
It is also recommened to those who enjoy anything paranormal. The first chunk of the series deals with spirits, from the benevolent to the malevolent, ghost stories to real hauntings, and it is quite interesting.
That being said though, the plot does go slightly downhill after a little while. It starts off quite strong, but then some aspects felt...a little watered down, or stretched out, if that makes any sense. First you start with the spiritial side, the human growth, the mystical side, Yuuko dealing with her clients, to parts of the plot that seem to try too hard. It's strange, and hard to explain.
Nevertheless, it is a highly recommended read. For the ending, you will either feel content with it or feel like something is missing/rushed/a little sad (It's up to you on how you will want to feel)
