True Gaia Memory

The Gaia Memor (地球の記憶, Chikyū no Kioku) also called the True Gaia Memory is a plot element in Kamen Rider Double as well as Earth's consciousness.

It was discovered below the Sonozaki Estate by Ryubee Sonozaki. After finding it Ryubee brought his family to see it, but his son, Raito Sonozaki died when falling into the "fountain," but he was then resurrected as the Gaia Memory's avatar. Knowing this gave Raito access to the planet's infinite knowledge, Ryubee began his plans for the Gaia Impact.

Through his son, Ryubee founded the Museum and had scientists create the Gaia Memories used by Dopants. Ryubee's wife, Fumine Sonozaki (Shroud) also created the refined Gaia Memories used by Kamen Riders.

After Raito was rescued by Sokichi Narumi and his protege, Shotaro Hidari (and was renamed Philip) the Sonozaki Family now use the temple under their estate for creating Gaia Memories.

Whenever the Xtreme Memory is used by Kamen Rider Double or when the ClayDoll Dopant evolves into ClayDoll Xtreme, data erupts from the fountain of the Gaia Memory to power those forms.

When starting the Gaia Impact and after it was messed up the Sonozaki estate collapsed burying the Gaia Memory.
