Gururi summary:

The story revolves around four main characters - regular old 10th graders, until they are chosen by a slip of Tatsuki's tongue to be the human masters of the ancient Four Gods! Readers of Fushigi Yuugi ought to know the four gods mythology. ^_^ The four teens are chosen to battle and vanquish the servants of the Demon King, who has escaped from the celestial world to wreak havoc on Earth.
