From the creator of Full Moon wo Sagashite comes a tale set in the 30th century, when the entire world is governed by a single kingdom called Earth. Princess Kyouko is nearing her 16th birthday, and a grand celebration is scheduled to take place across the nation. Unbeknownst to the public, the princess has been secretly residing among the citizens as Kyouko Suomi, a stubborn and self-centered junior high school student. Kyouko has never attended any of the kingdom's previous ceremonies, and she has no intention of going to this one either, as doing so would bring an end to her youthful school life. However, her father, the King of Earth, presents her with an alternative—Kyouko must locate the 12 telepaths capable of using the God Stones in order to awaken her twin sister, Princess Ui, who has been in a sleep since birth. If Kyouko succeeds, the king will permit her to live as she pleases and will transfer her duties to her sister. Accepting this proposal, Kyouko receives the first of the God Stones, the Time-Space Stone, and must find the remaining God Stones and their users, aided by her two bodyguards, Sakataki and Hizuki Jin.
