Warning: This article contains heavy spoilers
Episode 1: The Random Murders
Now that Bon is an official Time Patrol agent, he will go on rescue missions alone. His first mission is to rescue a young girl who was killed by a serial killer.
Bon travels in time to stop the murder and finds out that the victim he is supposed to save is none other than his friend, Yumiko.
When Bon tries to stop Yumiko from encountering the killer, the police mistake him for the serial killer, leading to Bon hiding in Yumiko’s house.
Bon has no choice but to tell Yumiko everything about Time Patrol and his missions. He even takes her to different time periods to prove that time travel is real.
Yumiko then time travels with Bon to save the woman who was killed in her place after Bon stopped her from running into the serial killer.
The two of them come across the killer, and when Bon messes up, Yumiko takes charge, beats up the killer, and rescues the other victim.
Yumiko promises to keep Bon’s secret on the condition that Bon makes her his apprentice. Bon then places a request for an apprentice, and it is approved.
Additionally, Buyoyon returns. Bon will not be going on missions alone; Buyoyon and his new apprentice, Yumiko, will be accompanying him.
Episode 2: The Sacrifice to Chacmool
Bon shows Yumiko the ropes of being a Time Patrol agent. Their next mission takes them to 1978 to the ruins of the ancient Mayan civilization.
They rescue Tarako Tarao, a manga artist, from falling to his death by preventing him from climbing the pyramid with the help of holograms of his children.
As Bon and Yumiko learn more about the historical site, they find out about how humans were sacrificed to the god of rain and thunder in a cenote.
When they learn about a young girl’s sacrifice through images of the past, Yumiko becomes determined to save that girl, Neesh.
They travel back in time, and once Bon ensures that helping Neesh will not change the course of history, he allows Yumiko to save Neesh.
Yumiko proves to be a brilliant agent. She comes up with the plan of making the people think that the gods have returned their sacrifice.
Yumiko manages to save Neesh, but she fails to change the tradition of sacrifice, as history cannot be changed. Rescuing Neesh serves as a training exercise for Yumiko, who shows great potential as a Time Patrol agent.
Episode 3: The Heike Fugitive
Bon and Yumiko’s next mission requires them to save a boy named Kamomaru during the Battle of Dan-no-ura between the Genji and Heike clans.
Kamomaru was from the Heike clan. He died by suicide along with the rest of his family after the Heike clan lost to the Genji clan.
Bon and Yumiko save his life and then send a white dove to guide him, making Kamomaru think that the dove is a messenger from the spirits who want him to live.
With the help of the dove, Bon and Yumiko unite Kamomaru with the survivors of the Heike clan, whom they know will be able to escape and live.
When the Genji clan’s guards nearly capture Kamomaru, Yumiko disguises herself as him and allows them to capture her instead.
After helping Kamomaru, Bon saves Yumiko from the Genji clan, who were planning to execute her upon discovering she was an imposter. Bon and Yumiko return home unharmed.
Episode 4: The Sumerian Boy
Bon and Yumiko travel to Sumer, Iraq, in 3319 B.C. In a village near Eridu lives a boy named Uru, who develops symbols to communicate with his friend, Geme.
Bon and Yumiko must save everyone in Uru’s peaceful village, which is going to be raided by thieves in a surprise attack.
Geme moves to Bad-tibira, but she and Uru are able to communicate by engraving their symbols on clay, which they send each other. Bon and Yumiko realize that they are witnessing the birth of writing.
When Bad-tibira gets attacked and burnt to the ground by thieves, Geme sends a warning to Uru, but the wolf that is carrying her letter is injured by the thieves.
Bon and Yumiko heal the wolf, enabling it to take the warning to Uru, who informs the villagers about it. Under Uru’s father’s leadership, the villagers prepare to face the thieves.
The thieves fail to catch the villagers off guard anymore and are defeated by them. The villagers also rescue Geme, who reunites with Uru.
Episode 5: The First American
Bon and Yumiko travel back 35,000 years to the Beringia land bridge. Their mission is to save a hunter who is traveling alone.
Exhausted and starving, the hunter is on the brink of collapse. Bon and Yumiko build a hut and provide meat for the hunter to allow him to rest and keep him warm and fed.
They then find out that the hunter comes from a village that faces harsh winters. The hunter believes that there are warmer and greener lands somewhere around, as he has seen the animals leave during the winter.
A few other villagers believed in the hunter’s theory and accompanied him, but they soon left him and returned home due to the unforgiving weather that they faced.
The hunter, unwilling to give up, keeps searching for greener lands alone. Bon and Yumiko continue helping the hunter survive in various ways without appearing before him.
The hunter’s efforts pay off: he reaches the west coast of Alaska, the land he had been searching for, and becomes the first man to discover America.
Later, he goes back to his village to bring the villagers to the land he has discovered. They settle down there and become the ancestors of all Native Americans.
Episode 6: The T・P Agent’s Crime
Bon and Yumiko are tasked with preventing a Time Patrol agent named John Defoe from committing a murder in 1667, in England.
John is going to murder a whaler named Zabrock. While Bon and Yumiko prevent the murder, they fail to capture John, who travels further back in time to make another attempt on Zabrock’s life.
Bon and Yumiko follow John and save Zabrock’s life once again. While they wait for the Criminal Investigation Unit to arrive, they hear John’s reasons for killing Zabrock.
John reveals that Zabrock, after fishing a whale, is going to meet a tailor who is going to get inspired to use baleen bones to make fashionable corsets for women.
The demand for these corsets is going to lead to the extinction of right whales, and John wants to prevent that, even if it means killing a person.
For breaking the Time Navigation Law and trying to change history, John is arrested, but not before Yumiko assures him that right whales still exist in the future.
In fact, their population is growing, as humans are now trying to conserve them. This new information consoles John.
Episode 7: The Beast Delb
Bon and Yumiko travel back 21,000 years to save a Cro-Magnon boy in France. The boy is going to be killed by a Coelodonta in the next few days.
The boy’s father was an excellent hunter but was killed by a Coelodonta, referred to as the evil monster Delb by the villagers.
After his death, the boy was taken out to hunt with the other villagers. However, the boy got scared, leading to the group losing their prey, which resulted in the boy being cast out by the village head.
The boy now plans to become a successful hunter in order to return home. Bon orchestrates a meeting between Yumiko and the boy with the intention of making them friends, and he succeeds.
Yumiko then teaches the boy how to make weapons to hunt. While she keeps him safe, Bon and Buyoyon look for the Coelodonta.
They find the beast, but Bon loses his Bio Controller, which is used to control animals. As the beast chases Bon, the boy comes to his rescue.
The boy manages to kill the Coelodonta with the spear he has made and becomes the hero of his village, bringing Bon and Yumiko’s mission to an end.
When they return home, Bon is approached by the chairman of an independent manga magazine who wants to publish Bon’s manga. Like the boy, Bon also finds his way in life.
Episode 8: The Day Troy Fell
Although it has not been long since Yumiko started working as Bon’s apprentice, Time Patrol recognizes her potential and promotes her to the position of an agent.
Bon is bothered by Yumiko’s early promotion, and it shows on their next mission, which takes them to Northern Turkey in 1229 B.C.
Bon and Yumiko have to save a slave girl, Menoa, who was killed on the day Troy fell. Bon is too proud to even consider Yumiko’s plan and decides to implement his own by himself.
Bon tries to rescue Menoa when the Greeks attack but fails. Yumiko, on the other hand, travels to 1868 to visit the ruins of Troy discovered by an archaeologist named Heinrich Schliemann.
After failing, Bon realizes that he should have listened to Yumiko and learned about the excavation site like Yumiko did before trying to save Menoa.
Once Bon realizes his mistake, he joins Yumiko. Together, they explore the excavation site and find a way to save Menoa.
They then return to the day Troy fell. This time, they succeed in saving Menoa and taking her to her home island. Bon also apologizes to Yumiko, who forgives him.
Episode 9: The Grim Reaper’s Horde
Yumiko and Bon travel to 14th-century France to save an old man named Isaac, who died because of the Black Death epidemic.
They dress up as traveling entertainers and convince Isaac’s daughter to let them stay the night at her house, enabling them to administer Isaac modern medicine.
They return to their present after that, but various aspects of the mission, which Bon did not know anything about due to a lack of research, keep bugging Yumiko.
Yumiko looks into the case and finds out that Isaac and his daughter were later arrested in the Jewish witch hunt. She and Bon then go back to save Isaac and his daughter.
Yumiko and Bon find out that as people did not know anything about the plague, they blamed the Jews for deliberately causing it, which led to the Jewish witch hunt.
Yumiko and Bon are also arrested, as they are found in Isaac’s house and believed to be witches. The lord of the town has fallen sick, but Yumiko recognizes that his symptoms are mild.
Yumiko accepts that she and Bon are witches and convinces the lord of the town to grant them three days to save his life and cure the town of the plague with their magic.
As Yumiko has done her research, she knows that the plague is subsiding in this town and that the lord will get better naturally, which is why she makes this promise to the lord of the town.
Three days later, when the lord of the town is cured and no more people die of the plague, Yumiko and Bon get the credit for saving them all.
They, along with the Jews, are released by the lord of the town. The mission teaches Bon the importance of researching in advance.
Episode 10: The Wrath of the Gods
In A.D. 79, in the State of Palestine, Bon and Yumiko must rescue a slave named Lazarus, who dies in a mine after it is hit by an earthquake.
They save Lazarus and help him get out of the mine alive, but Lazarus is captured and enslaved once again. Seeing him alive, Bon and Yumiko return home.
Bon and Yumiko are both curious about his fate, so even after returning home, they look into his future and find out that Lazarus saved the life of a Roman dignitary, Flavius.
Flavius then took Lazarus, who became Flavius’s favorite because of his strength, to Pompeii with him. Then, the wealthiest man in Pompeii invited Lazarus to fight Jason, an undefeated gladiator.
Flavius agreed to the fight, even though Lazarus, who was a Christian, was opposed to fighting and killing. Worried about Lazarus, Bon and Yumiko return to the past to save him.
They know that Mount Vesuvius is going to erupt and bury all of Pompeii in ash. They plan to take advantage of the chaos caused by the eruption to rescue Lazarus.
Their attempts to delay the match fail, and Lazarus is brought to fight a gladiator before the eruption. Lazarus, still unwilling to fight, does not even try to defend himself.
It is only after Lazarus is stabbed that Mount Vesuvius erupts. However, it is not too late to save him. Bon and Yumiko quickly cure his wounds and leave him on a boat away from Pompeii.
Bon not only worries about Lazarus, who is disillusioned by the world, finding his will to live but also about a flying object he had caught a glimpse of during the mission.
Episode 11: The Ruins Submerged in Rain
Bon questions his superior, Gayler, about the flying object he had seen on his last mission and finds out that Time Patrol agents have been trying to find that object.
He is told that his former mentor, Ream, was investigating and fixing space-time tears when she discovered that the cause of it was a mysterious sphere.
The sphere, responsible for recurring instances of unnatural space-time tears, has been running haywire in space-time and has gone missing.
If the sphere continues creating space-time tears, it might lead to the collapse of the entire space-time and the end of the world.
Bon wants to look for Ream, but as he is not trained to handle space-time tears, he is not permitted to do so.
Instead, he, along with Yumiko and Buyoyon, is sent to Mohenjodaro in 2400 B.C. to rescue a man named Amri, who has traveled there to trade his goods in the market.
Yumiko and Bon help Amri sell his goods faster so that Amri will return to his village before the flood hits Mohenjodaro.
However, Bon abandons the mission when he hears about the appearance of the sphere in Mohenjodaro about a century ago from a merchant in the market.
Bon travels further back in time to the time of the sphere’s appearance, whereas Yumiko helps Amri find his seal, which was stolen by the dancer he likes.
Bon finds Ream trapped inside the sphere, which is called the Dimension Ball. It spirals out of control and starts creating space-time tears everywhere.
Meanwhile, Yumiko successfully helps Amri sell his goods and return home before the flood comes. She then finds out that Bon left to save Ream.
Episode 12: Time Patrol Bon
Bon follows the Dimension Ball through the tears it creates. Ream is unable to open the Dimension Ball and get out of it.
She informs Bon that she met the inventor of the ball in Mohenjodaro in 2500 B.C. before Bon is sucked into a space-time vortex and loses Ream.
Bon, along with Yumiko and Buyoyon, then travels to Mohenjodaro in 2500 B.C. to save Ream, who risked her life by getting into the Dimension Ball to control it.
While they fail to prevent Ream from getting into the Dimension Ball, they take the device’s inventor, who is a researcher, into custody.
The device went out of control and began to rip itself through space-time when its inventor was experimenting with it, which is how he ended up in Mohenjodaro.
The device cannot be unlocked while it is still moving, but it will not cause the collapse of space-time, as it will self-destruct in case of unexpected accidents.
Yumiko decides to keep an eye on him until the Criminal Investigation Unit arrives, allowing Bon and Buyoyon to investigate the recent space-time tears to find Ream.
It turns out that Ream’s mentor, Rosa, also disappeared while trying to stop the Dimension Ball from creating space-time tears.
When Gayler hears about this, he asks Bon to leave the mission to the headquarters, but Bon and Yumiko both disobey his orders and search for Ream.
Buyoyon can smell Dimentron. With his help, they are able to find Ream, who has figured out the pattern of the Dimension Ball’s time travel.
Ream informs Bon where the Dimension Ball will take her next, and Bon reaches there with Buyoyon and Yumiko. Bon has a plan to save Ream.
He lets the Dimension Ball explode. With Yumiko’s help, he then reverses time in slow motion, enabling him to pull Ream out of the explosion.
Ream is rescued, but Yumiko and Bon must now face the consequences of violating the Time Navigation Law by causing a historical event. The Court of Inquiry will decide their punishment.
Once Ream is rescued, she is able to find Rosa as well with the information she now has. Additionally, the damage caused is minimized, as the explosion is believed to be caused by a meteorite.
As a result, Bon and Yumiko do not receive punishment. The season ends with the two of them leaving for their next mission.
