The story is about a spirit doctor, a monk, a snake spirit and a fox travelling around to the world helping spirits. There is not a big story but small stories of different individuals who received a helping hand by this spirit doctor. Some of these stories have twist plots and some tease your feelings.
Personally, i believe that the art is kinda childish but not bad.
There are many kind of characters, characters that you will love, characters that you will hate and meeh characters (mostly characters that you will love).
