A young girl, Kuniko Hojo, is released from the girls' detention center. She is picked up by her friends as well as her guardians, Momoko, Miiko, and Takehiko and returns to her home in Duomo. Kuniko is being groomed to be the future leader of Metal Age, a resistance organisation, which opposes the government's drastic policies on environmentalism. A high authority figure, Lady Ryoko, is informed of Kuniko's movements. Mikuni, a girl born from aristocracy, uses the highways of Atlas as her playground. Karin Ishida, a young computer genius, legally blackmails a politician from a 3rd world country into signing a banking contract with her company in Atlas, for overexceeding carbon emission. Takehiko recklessly burns fuel to celebrate Kuniko's return, in defiance on the government. The Atlas Security Corps and the military suddenly attack Duomo. Kuniko and the Metal Age members defend their town. They realise that Atlas is holding them responsible for an unknown incident. When Kuniko uses her boomerang on Major Kunihito Kusanagi, it hits his dagger, which causes Kuniko, Mikuni and Kunihito's sacred dagger to resonate. A moment later, mysterious black dots appear above Duomo and began raining down on everyone, causing mass destruction.

Episode 1

The black dots raining down on Duomo lead to everyone fleeing, including Atlas security and military. After the attacks stop, Kuniko and the other Metal Age members perform a search and rescue operation of Duomo's residents. Lady Ryoko is furious on the unknown attack and Leon, one of her men, volunteers to bring a team to investigate the source. Meanwhile, Kuniko, Momoko and Takehiko decide to investigate as well, at the place the attacks supposedly originated from: Ikebukuro. Their team wears protective gear to protect from the dense oxygen and poisonous swamp gas. Karin works with several of her peers to control investments and economy of other countries. However, she goes into a bad mood when one of her peers posts a presumably sarcastic remark. Mikuni punishes one of her retainers for lying by killing her with her psychic powers. Kuniko's team encounter a military squad sent into the Ikebukuro jungle to investigate. They are discovered by Kunihito and flee. Kuniko ambushes Kunihito and interrogates him on the military's presence, and the resonance of their sacred blades. Kunihito claims not to know anything and Kuniko escapes. Ryoko's men find that the artillery attack emitted no carbon dioxide, leading them to wonder if it's nature's punishment on them. Atlas begins the regular ballot to allow Duomo residents to live in the city and Miiko is one of the chosen. Ryoko gets an audience with the lord of Atlas, telling him that the seals have resonated.

Episode 2

Kuniko has a strange dream of Atlas, and learns from her grandmother, Nagiko, that her biological mother lived in Atlas. Takehiko and other Metal Age members raid a train from Atlas for supplies. Kuniko, Momoko and friends celebrate Miiko's departure to Atlas. Momoko entrusts Miiko with reopening the Tropical Fish, a bar staging Burlesque shows. Residents of Duomo get into an argument over Metal Age's responsibility for the attacks and their overall role. Kuniko wonders if everyone would be happy if they are able to live in Atlas, and makes a decision to go to the city. Karin is informed by her peer that she apparently messed with Saudi Arabia's carbon coefficient, thus making the latter rake in less money. She is confused by the apparent spike in the carbon economy. Ryoko's men find no new movements from the owners of the Sun and Moon blades. Kuniko, Momoko and Takehiko sneak into Atlas by faking identities as construction workers heading into the city. Miiko is forcibly recruited to be Mikuni's replacement retainer. Kuniko gets discovered while heading through a checkpoint in Atlas' support column and the group flees. They are chased by security, but fortunately an earthquake occurs and the group uses the distraction to escape. Kuniko wonders why everyone is not allowed to live in Atlas even though there were enough space to do so.

Kuniko muses on the vision of Atlas, and decides to finance a rebellion against Atlas by selling the community's store of graphite (which is rich in carbon). Escorted by Momoko (over Takehito's objections), she travels to the black market in Neo-Akihabara, a place still populated by electronics shops and otaku, where she encounters many colorful figures, some of them relics of our own time. In Atlas, we learn that Miiko has become a trusted retainer for Mikuni. Meanwhile, Karin and her companions become aware that someone else is manipulating the carbon market. Karin concludes that to do so, this other party must have duplicated their computer system, and she focuses her own search on Akihabara. While searching there, she notices Kuniko (seen through a security camera).

Karin convinces the Japanese government to use Kuwait as bait to lure out Serpent, despite the fact it will destroy that country's economy. Kuniko and Nagiko both watch the manipulation of carbon coefficient. Kunihito intends to resign for the loss of the mimic armor sample, but his superior tells him that Atlas has already pardoned him for this mistake. He is ordered to head for the Moon Palace to meet Mikuni. While Mikuni questions Kunihito on his recent events, Sayoko finds his Atlas rank is classified. She also discovers that his family blade matches the same material and shape as Mikuni's sacred blade. The lord of Atlas, Hiruko, goes hysterical from the thought of having the two blades meet. The government begins its hunt for Serpent. After Serpent takes the bait, Kuniko, with Nagiko's help, locates it originating from one of the islands in the Maldives. Ryoko obtains this information and sends it to America. Kuniko learns that America has dropped thermobaric bombs on the location, erasing Serpent's threat and stabilising the carbon market.

Ryoko arrives in the chamber once occupied by Hiruko, revealing a hidden passageway into the bowels of Atlas itself. Shogo, Leon, and Sion attempt to stop her, but she eludes them and they descend down through the shaft. Sayoko is quick to follow.

Back up in the ceremonial chamber, Kuniko and Kunihito finally manage to break through the barrier to the elevator shaft Ryoko took. Kuniko hugs Momoko and Kunihito apologizes for his actions. Kuniko playfully scolds him, saying he apologizes too much, before leaving down the shaft. Meanwhile, Karin is desperately struggling to stop MEDUSA's rampage across the economic markets. Talsian appears on the terminal and declares a way to stop MEDUSA. A rather comical chibi battle ensues and Karin is knocked into a separate field, greeted by the teddy forms of her parents, who reveal the real reason as to their extended absence. It's only a virtual program operated by Ryoko, but it turns out that Karin's parents had died three years before. Karin suffers a breakdown and Ryoko returns to reality to command Mikuni to draw the bejeweled spear and assume her role as successor.

It is revealed that Kuniko and Mikuni were artificially created and that Kuniko is in fact a clone of Himiko, the mummy of the goddess discovered beneath Atlas. It turns out that Ryoko's body is failing her and she intends to invade the body of the new successor. Outside, a figure resembling Takehito expresses his disgust at the use of human lives to construct Atlas just before setting off a chain of chemical bombs. MEDUSA has gained complete control of the computer systems. Kuniko is forced to draw the spear in an attempt to stop MEDUSA from starting a nuclear war, but she's too late, as nuclear missiles are launched all across the world, launching incomparable amounts of dust into the already weakened atmosphere. MEDUSA himself predicts a nuclear winter with dropping water levels and temperatures everywhere and finally relaxes, convinced that he's safe at last. But his plans are breached when he opens the floodgates of the islands, thinking them useless and releases a tidal wave crashing toward him. It turns out that the missiles launched were a ruse to get MEDUSA's guard down and release the floodgates holding the water back. MEDUSA drowns in the rising floodwaters and Karin mourns his and her parents' deaths.

Ryoko perishes and her life energy is absorbed by Zeus trying to revive Himiko. Sayoko appears in the catacombs, shaken but unharmed. Kuniko is carried away by the spear to the heart of Zeus where she meets Himiko, a duplicate of herself. Himiko plans to use all ten million citizens of earth to revive herself. Kuniko and Himiko face off, fighting for the future of the world. Kuniko's boomerang slices through the heart of Zeus, shutting the system down and banishing Himiko. Down in the catacombs, Miiko appears to Mikuni with the spirits of Hiruko and all of the sacrificed children.

Karin laments the loss of her money, of MEDUSA and of her parents and Klaris and Zhang make their first appearances, claiming to have been worried about their friend, Karin. Karin brings out the microchip that was MEDUSA and it suddenly manifests as a miniature version of the previous program, which Karin reveals as MEDUSA's baby. It quickly recognizes her as 'mommy'. Zhang says that this time, they'll raise it properly. Atlas is destroyed and Kuniko and Kunihito gaze out over the horizon. Kuniko states her dream of creating a Shangri La.
