The episode opened with the story of the post-modern feudal world of Filament, which was destroyed when its sun went supernova. An energy cloud formed where the planet used to be, and its inhabitants, not accepting their untimely fate, became spirits.

Nanmi, a passenger on the 999 is able to convince the train to head to his planet, El Alamein, when he threatens to kill Tetsuro. Once they arrive Tetsuro and Maetel travel outside with him. The planet is mostly a desert, with many inactive tanks lying around. Sensing their life however, the tanks come back to life and attack.

The 999 landed on a planet called "Rifle Grenade", where slaves were brought in to fight a perpetual war between two factions as spectator sport. One of the slave soldiers, Zeda, escaped and found refuge in the hotel room of Maetel and Tetsuro.

At gunpoint (from the previous episode), Tetsuro told Zeda of his struggles back on Earth. Zeda was instead moved and decided to joined the rebels. With his companions Santana and Brudas, Zeda managed to unite the two soldier factions and started to attack government facilities.

Tetsuro and Maetel arrive on a planet filled with kind hearted, hard working people. When a storm ends up destroying the hotel that they are staying in, their luggage, including their passes are lost.

The 999 arrives at the ghost tunnel, a giant tunnel in space formed by giant black orbs. An android woman, Eroze appears and asks Tetsuro to come off the train. When he refuses, she attacks the train with the orbs until he relents and agrees to come out.

As the 999 approaches its next destination, a large number of small blue blobs start passing by the 999, warning it to not go any further. Eventually the 999 gets stuck in a larger version of these blobs, which apparantely is their mother. The Galaxy Railways headquarters gets ready to blow it up so the 999 can go on, but all of a sudden a ship crashes into the blob.

After being brought aboard the 999, Artemis reveals her history, how she departed her mother to acquire a humanoid machine body. Having to work to pay it off in a factory had its toll however, and she stole a ship and fleed. Artemis dies soon after and is brought to the heart of her mother, where she is absorbed into it. With Galaxy Railways headquarters planning to destroy the mother, Tetsuro cries out for them to not do it.

A boy who looks just like Tetsuro, named Manabu, and his brother work hard and are able to purchase a single pass for 999. The brother passes away before they can make it to the town where 999 arrives. When Tetsuro goes out on his own, Maetel mistakes Manabu for him. Tetsuro arrives and fights Manabu, but they quickly become friends as they have so much in common. When Manabu tries to board the 999 however, he is told that the pass is counterfeit.

The 999 arrives on the Planet of the Endless Summer, which is populated by humanoid insect like creatures. The queen of the creatures captures Tetsuro and Maetel, planning to boil them to make them food for her children.

The insect babies hatch and when Tetsuro finds himself unable to kill them, they climb aboard the 999 and start eating it.

The 999 arrives on a primitive planet populated with people who are scared of the passengers taking over the planet. Meanwhile a friendly dinosaur named Tiny befriends Tetsuro and tries to get passage on the 999.

Tetsuro and Maetel arrive on the planet Footsteps Village, and are told of evil spirits that possess and kill people. Tetsuro is warned to not go out at night, but when he meets a spirit that takes the form of water, he does it anyway.

The 999 stopped on the planet Idle One's Mirror, where everything is automated by machines. Tetsuro disembarked the train alone, and was taken by an automated taxi around the city. Once the taxi brought him to a residential area, he found out that the all residents are obese from the lack of physical work.

The next stop for the 999 was the Planet of Tomorrow, a peaceful world whose inhabitants had no knowledge of space flight. The 999 and its passengers were to land in secrecy. A group of youths, led by Taro and Hanako, anticipated for its arrival. While the group only wanted to publicize the train's existence, Taro wanted to board the train. In doing so, Taro stole the train passes and spending money from Tetsuro and Maetel, as well as Tetsuro's clothes. In their plight Tetsuro and Maetel managed to find lodging in a small hostel (i.e., the pint sized room), where Tetsuro befriended the struggling comic-artist Adachi, who had been looking for an inspiration for his work. The episode ended with Taro offering Maetel's pass to Hanako, who refused it.

While stranded on the planet without train passes, Maetel sought help from Galaxy Railways, but her efforts ended in vain. Meanwhile, with Adachi's help, Tetsuro found a job at a noodle shop to support himself and Maetel. Tetsuro and Maetel ran into the disguised Taro when they returned to the train station. Taro, not wanting to leave his friends behind, gave the passes to them, not knowing at first, that they were the rightful owners. As the train departed, Taro returned to Hanako and their friends. And Adachi, who also saw the train leave the planet, finally found inspiration for comic.

As the 999 approaches the City Without Night, Maetel tells Tetsuro of a lake there, but tells him not to go out to see it. When they arrive on the planet, Tetsuro gets in trouble for going out at night, but is saved by Maetel. They are told that no one is allowed out at night because of a dangerous dinosaur, Heron, that lives in the lake. Tetsuro and Maetel head there anyway and help Heron when it is captured by some photographers. Heron actually is a friendly creature, and later helped Tetsuro and Maetel out when the police try to arrest them for the death of the photographers.

The 999 stops at the Pitch Dark Planet, where all light is instantly absorbed. A while after Maetel leaves the train to "attend to private business", Tetsuro is beckoned outside by a figure at his window, who proves to be Miru, a daughter of the planet's ruler. She and her father tell him that Maetel has been kidnapped by Miru's sister Lelan, a deranged but brilliant scientist who plans to use Maetel's brain to launch an artificial sun into orbit, and that Maetel will die unless Tetsuro can infiltrate Lelan's base and kill her. Further, the new sun will doom most of the life on their world, which has never had light in its entire natural history. Tetsuro goes back for his gun, but is taken prisoner by Lelan the instant he steps off the train. His efforts to escape prove futile and Lelan launches the sun. Miru, horribly burned, staggers into the base and tries to shut the sun off but is shot by her sister. Maetel accosts Lelan and accuses her of genocide but she retorts that sacrifices must be made for the greater good. She runs out into the sunlight and is burned to death. As the train leaves, the Conductor reports that 99.99% of the planet's population has perished.

Maetel and Tetsuro arrived at the Planet of Silence, where raising one's voice (beyond a whispering level) was punishable by death. Maetel asked Tetsuro to stay behind while she had to attend to some private business (concerning her "mission" with Tetsuro). Bored and worried, Tetsuro went looking for her. The townsfolk could not tolerate his voice, and was soon caught by the authorities to be executed. He was rescued by Maetel and a woman named Sylvia (in a Good, Bad, and Ugly way). Sylvia revealed that the law was enacted because everyone wore hearing aid to better listen other people's business, a vestigial legacy of a former totalitarian regime. Sylvia's father was executed when he cried for help to save her, when she was still a baby. They were discovered and surrounded. Knowing their weakness, Testuro screamed at the crowd so loudly, that their hearing devices fell out. The planet returned to normal as the train departed with Maetel and Tetsuro on board.

The 999 arrives at a planet where the people are starving because the Queen of the planet orders all food to be brought to her. Tetsuro and Maetel travel to the island where the Queen is located and find that she died long ago, with her consciousness stored in a device behind her corpse. Tetsuro destroys the device and her corpse, freeing the planet from her oppression.

As the 999 touched down on the Funeral Planet, its arrival (and whistle) disturbed a funeral procession, who decided to bury Maetel and Tetsuro alive as punishment, with the proper pomp and circumstance. They were rescued by Machiru, a woman responsible for ringing the funeral bell. She explained that the inhabitants on the planet were immortal, so killing for funerals became a past time when they witnessed one over 120 years ago, when a couple crash landed on the planet. The bell stopped ringing, and Machiru was killed by the procession as a result. Maetel and Tetsuro came across the procession and stunned them all. Maetel explained to Testuro that funerals would be given to them when they stopped moving, whether they were still alive or not.

Dairuz, a monk with a mechanical body was on board of the 999. His rang his bell throughout, and the sound waves were powerful enough to damage the train and all of Tetsuro's teeth. The Conductor took the train to the Medical Treatment Asteroid for an overhaul as a result. Maetel and Tetsuro met Maria, who brought her boyfriend Mikhail for gunshot treatment from their homeworld, the crime-ridden Asteroid 33. The operation was successful, but Mikhail was losing his will to live. Dairuz tried to save him with prayers, but it was Tetsuro who gave Mikhail hope to live on. Despaired, the Dairuz smashed his bell, and sacrificed part of his body so that Tetsuro's teeth could be fixed. In parting, Dairuz, who was now attached to a rock to sustain his body, told Tetsuro he had to remeditate to change his way of salvation.

The 999 passes the Curiosity Planet, a planet with a large red dot on it that makes the planet look like an eye. The Conductor orders the passengers to not stare at the planet, but one of the passengers, a young woman named Miiru whose boyfriend was pulled out of the train to the planet does. This enrages the planet, which sends its moons after the 999 and orders the passengers to come off. There they find Miiru's boyfriend. The planet demands that the Conductor remove his clothes, which he refuses. Tetsuro and Maetel do so instead so he doesn't have to. The planet then demands Maetel be cut open so it can see her insides. This enrages Tetsuro, who using a knife from Miiru's boyfriend cuts open the planet. Exposed, the planet is embarrassed and commits suicide after the 999 flies safely away.

The episode opened with an armed robbery that took place on the 555 when it took a stop on the Medical Treatment Asteroid (in Episode 67). Next, the 999 received an emergency stop signal and the Conductor halted the train in mid-space. Maetel was summoned by the C62 (the locomotive for the 999), who informed her that it was going to disconnect and go on its own. News of both incidents reached the Galaxy Railways Headquarters, and one of the operatives determined that both trains were on the asteroid when the heist occurred. The Conductor later discovered that the two robbers were on board the 999, and soon after the SDF appeared. One of the robbers took Tetsuro hostage and demanded that the SDF be attached to the 999. While the 999 continued with its journey, the C62 returned and attached itself to the train. Tetsuro and Maetel used the opportunity to pacify the two perpetrators and handed them over to the authorities. At the end, Maetel revealed that the the emergency stop was a test of Tetsuro's patience, and that the C62 was also part of the plot in bringing the boy to Andromeda.

The 999 stopped at the City of Flowers, which was covered with flowers. When Tetsuro and Maetel went to the Hotel, a fire broke out that ravaged the planet (and the flowers). The train made an emergency take off, while Maetel and Tetsuro were rescued by Coa and Rea (who started the fire), and their children Mia and Doa. The flowers, Coa explained, were poisonous, and those who destroyed them were executed. The police discovered Coa's role, and ordered his execution. The family refused to come out, and the ploice threatened to seal their entrance. The people rose up in defiance, however, and the police captain was forced to back down. Now on board of the 999, Maetel and Tetsuro contemplated on the significance and irrationality of Coa's (and his family's) sacrifice.

The River of Purgatory was a barren planet, and crops often grew with great difficulty. Almost all of the pioneers sent to the planet either died or left. Gombei and Yosaku, father and son, were the only two left on the planet. While Gombei kept on ploughing the field, believing that one day his hard work would prevail, Yosaku wanted to leave the planet. A giant bird flew to Gombei's field and picked Gombei's crops. Though Tetsuro managed to chase it away, it came back and started eating off Yosaku's field. Gombei tried to drive it off but was injured. Seeing this, Yosaku came to his father's defense. Tetsuro gave the fatal blow to the bird, and Yosaku, decided to remain on the planet, and worked the land until it became fertile.

While traveling Great Dark Nebula, the Conductor was taken away by a two-dimensional people called the Ghost Hoppers. Meanwhile, Tetsuro was temporary blinded by the triple Sun in the system. The train the proceeded to land on the ice planet Kilimanjaro, where the same Ghost Hoppers also kidnapped Maetel and Tetsuro. They, and the 999, became experimental subjects for the Ghost Hoppers.

While experimenting on the 999, the Ghost Hoppers put the three to a nearby jail. One of the Ghost Hoppers explained that they colonized Kilimanjaro two years ago, and eradicated the local aboriginal population. The artificial suns (which became the triple sun) they launched resulted in their two-dimensional appearance. The Ghost Hopper Queen's mothership appeared to halt the experimentation. She restored the 999 and released the three. The Queen, disgusted by the unethical pursuit of science by her own people, also left the Nebula.

The Gimme Planet was the next stop of the 999. It is a planet where begging was the only way of life. Maetel explained to Tetsuro that in the past, the planet was divided into an impervished working class, and an extremely corrupt ruling class. Idleness eventually became the only means to combat corruption, so everyone on the planet turned to begging. Two beggars, Ikari and Nasake, could not tolerate the attitude of the people and became bandits. They sneaked into the 999, robbed the train and took Tetsuro hostage. However, Tetsuro was persuaded by their determination of not willing accepting charity, and his convinced the Conductor to disconnect their car so that they could go free to another planet. Maetel told him that, though their future is unknown, his trust and friendship gave them hope to start a new life.

The 999 was forced to land with water-borne inhabitants. Maetel and Tetsuro were escorted to meet with Waterpress, the ruler of the City. They were ambushed by a group of native Cheyenne Fish led by Geronimo, but escaped unharmed. Waterpress held Maetel and Tetsuro hostage, wanting to use the 999 to escape the planet with his people, since they have exhausted all of the planet's natural resources. Geronimo went on his own way after, an argument with his brother Navarro, leader of the Cheyenne, who preferred to live in peace with Waterpress. Waterpress was confronted by Geronimo, but he managed to trick and kill him. The 999 departed. Navarro and Suzie found Gernonimo's body.

The Galaxy Railways were notified of the hijacking, and dispathed the SDF to neutralize Waterpress. Meanwhile, Navarro, Suzie and a few Cheyenne warriors began their pursuit of the 999 with one of Waterpress's prototype spaceships. The Conductor subdued the hijhackers, while Navarro boarded the train, but Waterpress and his men took Suzie hostage. Tetsuro and Navarro planned an attack from outside of the train, and neutralized Waterpress. Navarro and Suzie returned to rebuild their homeworld, while Maetel and Tetsuro continued with their journey.

The Rainy Pond was the next stop for the 999. A pilgrim warned the passengers of a witch who devoured life, and wanted the Conductor to leave the planet earlier. A flood came, and all the passengers were stranded on the hotel. A woman (revealed to be Arc in the second part) offered a boat ride for a price. A businessman tried to pay his way, but a young man, Columbus, took his money and pushed him into the water. He took the ride along with his girlfriend, Poem, who did so reluctantly. When the hotel was finally destroyed, the pilgrim drifted away, and Tetsuro lost sight of Maetel. Tetsuro was washed up on an island. He entered a lighthouse and was greeted by Arc and the Queen of the planet, Cueflame. Cueflame was the one who extract life flames from her victims to consumed them to attain eternal life. Her next victims were Columbus, Poem, and Maetel.

Cueflame began extracting life flame from Maetel, but Tetsuro took the flame before she could consume it. In a confrontation Tetsuro discovered that Arc was a cyborg who was working for Cueflame to reclaim her human body. Meanwhile, Columbus woke up and pledge his service to Cueflame, on the condition that he and Poem could also consume the life flames. After Columbus captured Tetsuro, the Queen rewarded him with the life flame, but killed himself when he was told that the flame was extracted from Poem. The Queen asked Arc to extract Tetsuro's life, but instead she restored Maetel's life, and extracted her own. The Queen became weak after drinking Arc's flame (since she was only a cyborg), and was killed when her fortress collapsed. Maetel and Tetsuro raced back to the train as the planet was ripped apart by natural disasters.

A mysterious caped man appears on the 999, who stops a fight between two men and later rescues Tetsuro from another man. The 999 arrives at the planet Heavy Melder where Maetel and Tetsuro split up. Tetsuro wanders to a bar where the bartender tells him of the Time Castle, which is supposedly ruled by Captain Harlock. Tetsuro also meets Leryuzu, a singer who is sister to Ryuzu (episodes 7&8), who tells him that Maetel has headed to the Time Castle.

Tetsuro returns to the bar to find the location of the Time Castle and once again is rescued by the caped stranger. Tetsuro rides a motorbike to the Time Castle, but is stopped along the way by some soldiers who are led by Leryuzu. At the Time Castle Tetsuro finds Maetel confronting Captain Harlock himself. Harlock throws Tetsuro back in time, to the day that his mother was killed by Count Mecha.

Leryuzu returns Tetsuro to the present and ties up him and Maetel. Maetel reveals that the Harlock ruling the castle is not the real Harlock, putting some doubt in Leryuzu's mind. Leryuzu confronts the fake Harlock, then destroys the Time Castle, the fake Harlock and herself. Tetsuro realizes that the caped mystery man was the real Captain Harlock, and he sees the Arcadia take off from the planet.

The next station for the 999 was called Butterfly's Dream. The inhabitants had wings (like butterflies) but they also have a very short lifespan (also like butterflies). They met Leaf and Kureha. Leaf, an artist, was wingless and was shunned by the locals because of it. Kureha was in love with Leaf, but she was also engaged to Hanza. Kureha called off the engagement and went to the forest with Leaf, but Hanza took her back with the help of thugs. When the 999 was about to leave, the autumn wind signalled the end of Kureha and Hanza, but Kureha found Leaf before she died in his arms.

The 999 reached a system when a battle took place between two planets, Maya and Zaba. Meanwhile one of the planets in the system was about to explode and destroyed the two worlds.

Seth activated the genetic reinforcement device, which supposedly nullified the effects of the planet, while Rei watched over him.

Tetsuro intercepted a message in a bottle on the train. It was sent by explorer J.F. Stanley, who was left stranded on the Planet of Giant Elephant with his wife, Merusa, and his assistant, Narl. They were searching for a giant elephant called Flame. The Conductor reluctantly stopped at the planet to look for them. They located Stanley's party, but Stanley instead wanted to stay. Narl knocked him unconscious and took off with Merusa when Tetsuro and Maetel were trying to bring him on the boat. Flame appeared and killed Narl. Stanley's wife suffered minor injuries. Stanley wanted to break camp and pursue the Queen, who controlled Flame, while the rest grudgingly followed. When the Queen finally appeared, and instructed Flame to kill them all.

The agent was moved by Tetsuro and released both of them.

The 999 was searched by Brittenian soldiers when it landed on the God Given planet. Maetel and Tetsuro met Nasuka, one of the soldiers who was sleeping on the job. Tetsuro later found Nasuka, who was taking a boat to Honiara Island, where the planet elder resided. The two entered a cave and found the elder, who informed them that the planet was about to enter an ice age, but this would also waken the sea-dwelling Suraoids. On their journey home, Tetsuro and Nasuka found his lover Elza, a Suraoid injured in an underwater attack. They were discovered by fellow Brittenian soldiers, and the captain arrested Tetsuro and ordered the execution of Nasuka and Elza. Maetel appeared and drove the troops away. Nasuka and Elza left to find a place to live their lives in peace.

The 999 approached the Planet called Crossroads of Destiny, where its blue satellite planet was about to go extinct. The planet was inhabited by a people who returned to a survivalist society when it ran out of natural resources. Tetsuro met Yaku, a weak hunter who was experimenting with new weapons. When his companion Aya decided to leave him for Mu, Yaku went to confront Mu, but was badly beaten.

The Sheriff found his men captured, and the mayor was about to be executed by the townsfolk.

Maetel and Tetsuro arrived at Snowica, and Tetsuro was warned of the Snow Woman, who had the power to kill when the victim made eye contact. They met Tsuru, the most reputable ramen cook in Andromeda, but business was slow for him when people adopted mechanical bodies. While Maetel was away (discussing her mission on Tetsuro with C62), Tetsuro went to Tsuru's shop, and Tsuru told him a story of Yuki, a woman she used to love. But the Snow Woman appeared, who also wanted a bowl of ramen. To Tetsuro's surprise, he did not die when he made eye contact with her. However, the Snow Woman was disappointed when her ramen turned to ice when she touched it. Tetsuro sympathized with her and they left together. Tetsuro told her of his desire of a mechanical body, she promised to bring him to a place where he could receive one for free. The episode ended with Maetel looking for Tetsuro in the snow.

Maetel ran into Snowlock, a broker for mechanical bodies who was collaborating with the Snow Woman. Snowlock brought her to his workshop, but Maetel managed to destroy it. Meanwhile, the Snow Woman wanted to take Tetsuro's body so that she could eat hot ramen without freezing it. Tetsuro promised to make her ramen, but it also turned to ice when she touched it.

She died in Tsuru's arms as her ice body melted away.

The 999 reached the planet of Rainbow Sash. All that remained was a single underwater city resulting from a nuclear war. Maetel and Tetsuro went to the hotel, and saw the janitor Tadashi was unjustly dismissed by the manager. Tetsuro left the hotel in disgust and stayed at Tadashi's home. Kumi, the hotel receptionist, appeared, and they witnessed a car crash. It turned out the driver was, Miyoko Ohara, secretary to the governor. She warned them of an imminent earthquake that would destroy the city, and gave them the pass to the escape pods before succumbing from her injury. The 999 also departed, but Maetel convinced the Conductor to stay on the surface in case Tetsuro escaped. Once in the escape pod, the hotel manager emerged from the luggage prepared by Kumi, and tried to kill Tadashi, but was killed by Tetsuro, who also managed to sneak into the same escape pod. Kumi confessed that she was with the manager because of his power and money, but she loved Tadashi. They reached the surface and Tetsuro was rescued by the 999.

The next stop of the 999 was the Insect Planet. It used to be paradise for insects before the humans colonization, and the Conductor warned Tetsuro and Maetel of the recent murders that have been taking place. Maetel and Tetsuro came a cross a man murdered, and his caged insects were released. They went to the house of Futoshi, Keiko, and their family, where Tetsuro saw the murderer ran into, but they did not find the perpetrator. In the following morning, Keiko met Tetsuro, and pleaded him to become an insect with her. A group of insect people appeared and tried to kidnap Tetsuro, but Maetel appeared and saved him. They returned to Keiko's home to find that she was transformed into an insect. She was, indeed, the one behind the recent killings. Keiko asked everybody to leave the house, blew up her room and killed herself.

Yaryabol, instructed by his mother, altered the course of the 999 to his home world, where everything was of miniature proportions. As they entered the hotel, they received a dinner invitation from Yaraybol. Maetel was trapped in the elevator and Tetsuro was ambushed route and was captured by Yaryabol. Maetel escaped and found Tetsuro resting in Yaryabol's residence, where, true to his word, Yaryabol they proceeded to dinner.

The train passes through a loose zone where everyone becomes loose and lazy and otherwise irresponsible. Tetsuro gets thrown out of the train somehow and the Conductor and the train are too lazy to look for him. Maetel is virtually unaffected.

Ultimately the whole thing turns out to be just a dream.

Aron and Crosalis were lonely space drifters, transparent and without physical form. Aron turned himself into a train station (Ghost Station 13), so that he could have galaxy train passengers to land and play with his sister Crosalis. The 999 landed on station 13, but was trapped. Aron asked Maetel to provide her psychomagnetic waves (i.e., life energy), so that Crosalis could play with Tetsuro in physical form. Meanwhile, Galaxy Railways decided to destroy the ghost station, and advised the 999 to disembark immediately. The 999 could not escape in time, but Aron and Crosalis intercepted the destruction waves, out of gratitude for Maetel and Tetsuro.

Kilimanjaro (a different planet than in Eps. 71 and 72) was a world where chivalry still existed among soldiers. While in the 999, Maetel and Tetsuro witnessed a dogfight between two opposing squadrons. They later came across one of the captains (Alman), who bullied one of the squadmates, Izaka, for his poor upbringing and battle performance. Another dogfight soon followed, and an enemy pilot killed Izaka's civilian blood brother Kikuo for sport. Izaka singlehandedly took out the enemy squardron (included Captain Otto). He was arrested for unchivalrous behavior due to a recent ceasefire, but was rescued by Tetsuro. Izaka was pursued by Alman in another dogfight, but managed to escape, using the 999 as cover.

The Planet of Macaroni au Gratin, so called after its shape, was the next destination of the 999. Mane and Sab, the mechanical Dendorium brothers, who were bored with playing war games at the expense of the planet, captured (and shrunk) Maetel and Tetsuro so that they could escape the planet with the 999. They feigned a total war that destroyed the planet, but Queen Promethium (Maetel's mother) appeared and brought them to the train. Mother Computer Junior, discovered their escape and had them executed, while restoring Tetsuro and Maetel to their original size.

To make up for the delay in the previous episode, the 999 enters Warp Space. Unexpectedly, a duplicate 999 materializes alongside them and the two trains collide and become entangled. Crippled, the 999 and its double are drawn into the gravity of a sinister-looking planet that seems to be adrift in Warp Space. Tetsuro climbs though a breach into the other 999 and encounters an exact double of Maetel; however her companion is not his own double, but a different boy named Redril Hammer. Redril explains that he is traveling on the 999 to a planet where he will receive a mechanical body for free. The trains narrowly avert crashing down but the car carrying both Maetels breaks loose and falls to the surface.

The trains having landed on the Wandering Planet's surface to rescue the two Maetels, Redril and Testuro confront two extremely alien-looking creatures who refer to themselves as "humans". When the aliens confirm to their satisfaction that Tetsuro, Redril, the two Maetels and the two Conductors are flesh-and-blood and not mechanized, they are permitted to return to the trains. As they prepare to lift off, the Conductors are seized by a pair of mechanical creatures with a shape resembling that of the two "humans" they encountered before. They demand that the two boys surrender their passes and allow them to take their place on the train. The Conductors are aghast and ask to stay behind instead of the boys, who in turn object that they themselves should remain as the Conductors are too important to the other passengers. Startled that flesh-and-blood creatures could be anything other than cruel and selfish, the aliens relent and explain that the "real" "humans" who rule their planet are tyrants who ruthlessly hunt down and murder their mechanized "human" subjects. The boys remark that this is the reverse of their own experience, much to the astonishment of the two mechanized "humans", who conclude that they could never harm "real" humans as compassionate as them. The trains leave the planet, and exit Warp Space to return to their respective time periods.

On the Bat planet, the 999's last stop before the final destination, Tetsuro met a sickly young man, who wanted a mechanical body so that he could have the endurance to become a great animator. Like many travelers up to this point, Tetsuro recalled his encounters along the journey and expressed doubts in his decision to obtain a mechanical body. The young man broke into their hotel room stole Tetsuro's belongings, including his pass, so that he could board the 999 disguised as Tetsuro. However, he found this unethical, since he has already worked so hard travel up to this point, and returned everything to Tetsuro when he met them at the train station.

The 999 reached its final destination, the planet Promethium. Once on the surface, Tetsuro and Maetel were escorted by Mirai, who brought them to the sanitarium where Tetsuro had up to 24 hours to contemplate his decision on adopting a mechanical body. Maetel warned Tetsuro to think wisely before leaving him with Mirai to meet her father, whose consciousness was encased in a pendant. In the sanitarium, Tetsuro realized that the life of a cyborg was empty and disappointing, and decided not to take his machine body. He also witnessed a cyborg committing suicide and, in his last moments, warned Tetsuro of Maetel's intentions, and that she was the daughter of the Queen of Promethium. In a confrontation between Tetsuro and Maetel, Mirai explained that Maetel was to bring courageous young boys like him to help construct an eternal mechanized empire. The Queen's agents appeared and Tetsuro was arrested for defying the Queen's plans. She ordered Tetsuro and the 999 to be thrown into a nearby black hole. Meanwhile, Maetel's father instructed her to throw him (the pendant) into the planet's central reactor to destroy the planet and Queen Promethium. The plan was thwarted by the Queen, and Maetel was imprisoned. The episode ended with Maetel watching the 999 taking off, which was headed to the event horizon.

The Conductor and Tetsuro attempted to steer the 999 away from the black hole, but was immobilized by tractor beams from Promethium. In the mean time, Maetel was able to escape, and managed to turn off the tractor beams. The 999 was able to change course and returned to the planet to save Maetel. He ran into Mirai, and stopped her trying to kill herself for failing to persuade Tetsuro to become a cyborg. Maetel appeared, and the three agreed to work together to retrieve the pendant from the Queen. Though this time the plan successful and the reactor began to overload, Mirai was killed in the process. Queen Promethium disintegrated (but presumably not killed) in the final confrontation with Maetel and Tetsuro. They successfully boarded the 999 and returned to the Bat planet (ep. 111) as they witnessed the planet's destruction. Tetsuro decided to return to Earth with the 999 to continue his struggle against the cyborgs. Maetel boarded another train (the 777), and explained to Tetsuro in a note, that she must begin her journey once again with another boy like him.
