Time-Patrol Bon: Fujiko F. Fujio Anime Special - SF Adventure

Ordinary schoolboy Bon Namihira is caught in the middle of a mission carried out by Ream Stream, an agent who travels through history to rescue people whose survival will not disrupt the future. After witnessing technology that should remain secret, Bon is unexpectedly recruited into the Time Patrol rather than having his memories erased.

His first assignments carry him into dangerous moments of the past, where saving one person requires strict obedience to history's limits. Bon must learn that courage alone is not enough when even a small mistake can alter every life that follows.
