Kyoko Suomi / Time Stranger
Kyoko is the first Princess of Earth Nation and, at the beginning of the story, is seen as selfish, spoiled and lazy. Not to say Kyoko doesn't have any redeeming qualities such as being empathetic and usually puts other peoples' lives before her own. As the story proceeds, Kyoko learns different lessons and becomes a better person. Gradually, Kyoko realizes she's in love with Sakataki. At the end of the manga, she gets engaged to him.
Kyoko's goal is to find the twelve God Stones and the Telepaths that can use them so they can move the giant clock that supposedly keeps her younger twin sister, Ui, asleep and she can hand over her princess duties to her and Kyoko can live her life freely. It is later revealed that Kyoko had known since she was about ten years old that she wasn't biologically part of the Royal family and the real reason she wants to hand over her duties as a princess to Ui is because she believes they are rightfully hers. What Kyoko didn't know was that her body was actually Ui's in the first place and that when the clock was moved it wouldn't just awaken Ui it would force Ui's soul back into her body, in turn pushing Kyoko's soul out. Kyoko had been told by The King that he had found her on the day Ui was born and secretly adopted her into the Royal family without anyone's knowledge when she was a baby. At the end, when she returns to Earth, she takes over the body of The King's deceased wife.

Time Halt: Allows Kyoko to stop time for short instances.
Time Slip: Allows Kyoko to travel to any period in time, past-wise.
Time Return Excellent: Allows Kyoko to banish people into the time frame they came from.
Sakataki Jin / Crystal Stranger
Sakataki is a serious, straitlaced 17-year-old who only wants Kyoko to stop living on a whim and start acting more mature. He is one of Kyoko's bodyguards and rarely smiles, which is understandable considering his past. Sakataki is a Prince of the dragon kirito and would have been the next Chief had it not been for the fact that the Ryuuzoku (dragon kirito) had been wiped out when he was five, despite that the Ryuuzoku were know widely for their exceptional skills in combat.

He admits he's in love with Kyoko and after he was caught by his brother, Sakataki, kissing her while she was asleep and was jailed, Sakataki reveals that Hizuki had been found by their late father and because of this, Sakataki was treated better than Hizuki. Later on, it is revealed that Hizuki is a Mazoku (Demon kirito: mix of Human and demon DNA, immortal to all weapons except for the cursed sword, Li Nite) and was also the one who destroyed the Ryuuzoku village out of spite. He claims that it was not Sakataki who was saved that day, but him (referring to how Sakataki still called Hizuki "Brother" even though everyone knew that Hizuki was an outcast) and because of this belief, Hizuki tried to get Sakataki to kill him until Sakataki revealed that he knew Hizuki destroyed the village from the beginning. His God Stone is, Ironically, the cursed mazoku slaying sword, Li Nite. His powers as the Ice Stranger are unknown.
