Description:  In the 30th century, time travel becomes illegal after a time paradox crisis. The Time Protection Department (TPD) is established to watch for and stop time crimes. Four new enlistee cadets of the TPD are tricked by Don Dolnero and his gang into letting them time-travel to the year 2000 to commit various crimes and, to protect history, the four cadets pursue them. They encounter a severe problem: the Timeranger program requires five members for the first operation. They force a present-day martial artist, Tatsuya Asami, to join them, and they become the Timerangers. Tatsuya rents a building for them to live in, and they start a small odd-jobs business called Tomorrow Research to financially support themselves. Over time, the four cadets begin to realize that their presence would inevitably change the future in the form of the City Guardians, a security force under the employment of the Asami Corporation to protect the city from the Londers. The City Guardians form a tenuous relationship with the Timerangers, especially when Tatsuya's childhood friend Naoto becomes Time Fire and later the City Guardian's captain.
