From the introduction: Summary: In the year 7777 A.D., when another rotten genius alien girl, Oga, gets annoyed. She sends a robot to the past via her time machine. Oga is a member of Grays—but there is another alien from the same race as herself, Oga’s rival in the time traveling department, Kaya. Kaya and her friends—go to the location of the robot crushing Oga. To prevent trouble Oga’s robots had photographic shields preventing Kaya’s group from taking photographs to show Oga’s uncle who is the President of the United States that Oga is breaking the law—by changing the past. Kaya and her friends knowing they are breaking rules by time traveling—use Grag’s alien-outfits that give them the powers to fight against the robots—and call themselves The Time Fixers who fight against Oga’s Time Wreckers.
