Noah is a young boy whose parents are world famous as scientists who developed "Fairia seeds." Fairia seeds are special flower seeds that can "grow" fairy-like beings called Fairia. Fairias have become popular pets since the seeds became available for sale. Popular with everyone else but Noah. Noah swore that he would never keep a Fairia again after his mother used his Fairia in an experiment and killed it.

One day he picks up a houseplant from the garbage and brings it home without realizing that it is a Fairia plant. When it flowers, out comes a beautiful girl the size of a pea. He names her Claire. Claire is a special kind of Fairia called Fairial that can make themselves human-sized.

Now, Noah must find out the secret behind the Fairia seeds, if he wants to keep Claire safe.
