Garden of Rainbows

The Garden of Rainbows (虹の園) is the name inhabitants from the Garden of Light refer to Earth in the two Futari wa Pretty Cure seasons, and where the Pretty Cure and other humans live. A day in the Garden of Light is equal to a hundred years in the Garden of Rainbows because the flow of time differs in each world. This explains why Mipple was painted in a 100 year old painting after she fell to Earth. Creatures from the Garden of Light can only hold their natural form there for a short amount of time, so they take on the forms of the Card Communes/Heartful Communes or other related forms to save their energy.
