The Spring of Truth (真実の春 Shinjitsu no Haru) is a special pool in the Mamodo World that allows a mamodo to view events in the Human World and send non-living things to the other side. The school headmaster has the power to move the abilities of this spring to any body of water. It was only seen in the first movie and played a key role in Wiseman's plot.
