Indotokusatsu: Mirai Sentai Timeranger

Summary
In the 30th century, time travel becomes illegal after a time paradox crisis. The Time Protection Department 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. To protect history, the four cadets pursue them. There they encounter a severe problem: the Timeranger program requires five members for the first operation. They thus force a present-day martial artist, Tatsuya Asami, to join them, allowing them to become the Timerangers. Afterwards Tatsuya rents a building for them to live in and they start a small odd jobs business called Tomorrow Research to financially support themselves. (Wikipedia)
