The Tree of Life is an important force in Guardian Fairy Michel. Its energy sustains all life on earth. When the Black Hammer Gang kidnaps the Fairies of Nature, the Tree withers. Without it, the Earth itself is in danger of dying unless Kim and Michel (character) can rescue the fairies.

Rena keeps the seed for the new Tree of Life in her flowerpot, and is able to use it to sense where the fairies are being held. Laura is the spirit of the tree.
