is an eight-volume manga series by Kiyoko Arai about a 13-year-old girl named Meilin Kanzaki who is endowed with Feng shui powers which allow her to read people's fortunes and give advice on how to receive good luck.

Rin is in love with her friend Asuka Yuki, who is a star on the school soccer team, but she constantly bothers him with her Feng shui advice when he doesn't believe in any of that.

Almost as soon as she mastered talking as a young child, Meirin Kanzaki discovered her feng-shui powers and developed them to such a degree that she has developed an online help desk where she guides and counsels people under the pseudonym of "Dr. Rin" with such skill that she inadvertently leeches away significant commerce from her father Shou.

As is usually the case with 7th grade girls, Meirin is not immune to developing infatuation with boys her age; in Meirin's case, the boy of choice is her childhood friend Asuka who has a difficult time placing occult phenomenon such as feng-shui in perspective.

Meirin faces mysterious events and paranormal phenomenon of such complexity and treachery that she will need all the help and luck she can muster to save the day with her feng-shui divination and the hakke crystal bestowed unto her.
