While at his friend's home, Bon Namihira accidentally witnesses time travel in action and finds out that to keep it a secret, he must be erased.

After narrowly escaping erasure, Bon must learn the ropes of being a Time Patrol agent. His first mission: 1947 Tokyo in the midst of Typhoon Kathleen.

In his next mission, Bon is off to the very distant past of 2592 B.C. Egypt, where he works with Ream to save the innocent Thoth from being buried alive.

After getting an earful from Ream about flaunting his new gear, Bon and team travel to 800 B.C. where they assist an ancestor's risky sea voyage to Japan.

Bon and Ream go back 350 years, arriving in Southern France to prevent the torture and death of Celine, a potential victim of Europe's witch hunts.

While on a mission in A.D. 628 at the Tian Shan Mountains, Bon realizes that the group they're trailing inspired the epic "Journey to the West" tale

In 1500 B.C. on Crete, Bon and Ream experience the dire consequences of neglecting their Time Boats. Will they be able to save their targets in time?

Tasked with saving only one person during the Battle of Okinawa in 1945, Bon and Ream wrestle with the harsh reality of the Time Patrol's limits.

The crew takes a vacation to the late Jurassic period but ends up thwarting a poacher whose unrepentant hunting might threaten all of humanity.

Bon and Ream search for clues to their next target's identity in Tombstone, USA, where they must blend in with the 19th-century gunslinging crowd.

The crew warps to 490 B.C., saving lives at the Battle of Marathon. Later, Bon carelessly changes history and must take the place of an important herald.
