The stories revolve around some special dolls, the Plant Dolls, and the people who buy them. The dolls choose their owners, and desperately need their owners' love; they often reflect their owners' personalities for better or worse. Each story is independent of each other, though there may be references to knowledge learned in previous stories. Some stories have a fairy-tale like quality: they are eerie fables meant to warn against certain actions. There are several non-Plant-Doll related stories included in the Viz-released volumes as well.
