Meirin is a teenage girl with the power of feng-shui divination, an ability which her brother argues surpasses her father's. Most other characters tend to agree, if not through their actions then by flocking to her web-based divination service, for which she uses the pseudonym "Dr. Rin." Unfortunately, the online service costs her father, who does his own feng-shui divination service, many of his customers, and so she tries hard to keep her secondary identity a secret.
