T・P Bon

A junior high student named Bon meets Ream Stream, a Time Patrol agent from the future, and a creature named Buyoyon. The Time Patrol rescues people who died unexpectedly, without changing major historical events. Those who witness the agents have their memories erased, but Bon's remain. He becomes a trainee and joins Ream on missions. Using futuristic tools like the "time boat," Bon explores different times and places. Though sometimes reckless, he learns from the people he meets in various eras.
