The chapters were collected into a single bound volume on September 23, 2005, and was later re-released in two volumes by Kadokawa both released on October 25, 2008. A manga series adaptation drawn by Tasuku Karasuma started serialization in Kadokawa's Ace Assault in January 2009, but was later transferred to Shōnen Ace. An anime television series, directed by Makoto Bessho, written by Hiroshi Ōnogi and featuring character designs by Range Murata and animation character designs by Kumi Ishii, premiered in Japan on April 6, 2009.
Plot In the mid-21st century, the international committee decided to forcefully reduce CO2 emission levels to mitigate global warming. As a result, the economic market was absorbed predominantly by the trade of carbon. A great earthquake destroys much of Japan, yet the heavy carbon tax placed on the once-industrialized country is not lifted, so Tokyo is turned into the world's largest "jungle-polis" that absorbs carbon dioxide. Project Atlas is commenced to plan the rebuilding of Tokyo and oversee the government organization, which the Metal Age group opposes due to its oppressive nature. However, Atlas is built with enough room for only 3,500,000 people, and most are not allowed to migrate into the city. The disparity between the elite within Atlas and the refugees living in the jungles outside its walls sets up the background of the story.
Characters
Main characters
A young girl who skillfully wields a light-weight boomerang, made from high-carbon steel, in the defense of her town from the military or anyone who seeks to intervene. She is extremely athletic and has a rambunctious personality. Kuniko is affectionately known to the residents of Duomo as Kuni-chan. She is also referred to as The Sun, and Atlas members call her Digma 2. At the start of the series, she is released by Atlas from the women's detention center after a two-year sentence for domestic terrorism, rejoining Momoko, Miiko, and Takehiko while still in her old high-school uniform. Although not part of Metal Age, she is considered the future head of the anti-government organization due to her grandmother's position. She is a clone of Jimmu (Himiko in the anime).
A very pale little girl. She suffers from a collagen disease and thus cannot bear sunlight. She has the uncanny ability to see through lies and habitually puts liars to death by some unexplained ability to manipulate and crush the offender's body (in the manga version, the origin of this power is the Mirror of Yata, lodged in one of her eyes). She carries a sacred dagger identical to the ones Kunihito Kusanagi and Kuniko have, as well as an earring matching the one Momoko wears. She is referred to as "The Moon" and also as Digma 1. Strangely, in the manga adaptation, Mikuni's emblem is the three-legged solar crow, Yatagarasu, instead of the Imperial Seal of Japan, a Chrysanthemum Crest stylised as a golden sun like flower (it is also considered as the symbol of the Japanese Civilisation).
A military officer who works for Atlas Corporation under Leon's lead. He does not want to hurt others as much as the Atlas military does. He carries a sacred dagger identical to Kuniko's and Mikuni's, except that the tip of his dagger is broken. He is a distant descendant of Jimmu (Himiko in the anime). Kunihito is referred to as The Land and as Digma 3.
Duomo A city surrounded by deadly jungles where the main characters live. Duomo is home both for citizens and for the headquarters of the Anti-Government organization Metal-Age. It is eventually destroyed during the burning of Tokyo to eradicate the Daedulus.
A trans woman with a flamboyant personality. Momoko tends to pick on Miiko but seems to care for Kuniko almost as a daughter. Her weapon of choice is a whip that is coiled around her arm until she activates and uses it. She has a liking towards men, and often attacks them by forcing upon them kisses or other uncomfortable encounters. She is one of the owners of Tropical Fish.
Kuniko's grandmother, the head of Metal Age. She places a strong emphasis on learning and is much sterner and reserved than Kuniko is. She expects Kuniko to become the next leader of Metal Age though Kuniko does not want to be. She disagrees with using the internet for information, and gets her knowledge from the many books she has. Nagiko is actually the first CEO of Atlas Corporation and received funds from Sergei Talsian in order to build the futuristic city for their descendants. After Kuniko confronts her about this fact and receives no explanation, she is forced to expel her grandmother from Duomo. However, Nagiko reappears later on to help Kuniko to negotiate with Ryoko to grant temporary shelter inside Atlas for the inhabitants on the surface so that Metal Age can eradicate Daedulus by burning Tokyo down.
Kuniko's friend. A slow-paced girl who always tries to see the bright side of life, often ending up in just not seeing anything at all. Desperately wanting to free herself from her family name, she has a strong wish to be married. She is very interested in boys and dates many guys.
Kuniko’s friend who goes to all-girls high school, a girl-next-door type with slightly gloomy air. Though she is yielding toward Kuniko, she is not afraid of reproving Yuri. It is revealed later in the series that she had stabbed a citizen two years earlier and that Kuniko had taken the blame to protect her friend. This resulted in Kuniko's two year prison sentence.
A driver and a rough-and-tumble guy. He regulates the electricity production in the town of Duomo. He often seems reckless but is unfailingly dependable. It is revealed that Takehiko was an agent sent by Atlas to watch over Kuniko, under the code-name #13. He strongly believes in the construction of Atlas, but this belief was shattered when he found out that his younger sister Yasuko was kidnapped by Atlas and used as a sacrifice with other children in the city's construction. Losing all hope, he attempts to kill Kuniko in order to ruin Atlas' plans but is stopped by her and Kunihito. He tells Kuniko her true role as inheritor of Atlas before seemingly killing himself by jumping into a storm drain. He reappears at the ending where he tries to destroy Atlas.

Eventually rising to the position of Japan's Prime Minister, she shows little concern about everyone or everything except her plans and herself.

Sayoko takes her and Mikuni away from Atlas. She sacrifices herself and Hiruko to save Sayoko and Mikuni by shielding them during the bombing of Neo Akihabara presumably using all of Hiruko's power to accomplish this. At the end, she reappears in front of Sayoko and Mikuni to bid Mikuni a final farewell and using some kind of power to cure Mikuni of her disease and deadly ability. She also asks Sayoko to take care of Mikuni like a real mother before disappearing with the souls of the other children who were sacrificed over the years during Atlas' construction. Her birth name is .
Mikuni's protector. She watches in delight as Mikuni sees through the lies of people and puts them to death.

Ishida Finance
A little girl who enjoys manipulating the world economy through the carbon-credit market, and one of the creators of MEDUSA. She hides her true face when talking to others through her computer console because she doesn't like people. She possesses a teddy bear (named Pudding) which she does show to the camera and to which she talks as if it were a real person. Pudding "responds" to Karin's comments, though it is actually Karin talking to herself in a funny voice. Her parents actually have died in an air crash, but she is made to believe that they are very busy with work, leaving her alone all the time. Karin buys out the entire Akihabara for her own after getting tired from shopping around. After she tries to hack into Zeus, she is pursued by Atlas authority. She escapes arrest by escaping to Akihabara. As the story progresses, her personality becomes slightly accepting of people as she only hides her eyes with sunglasses when she talks to them.

A friend of Karin's, Talsian seems to have a connection to Karin's parents, and doesn't talk during instant-message conversations. Talsian makes a physical appearance from halfway through the series. He is chairman of Atlas Corporation, and apparently knows Ryoko well. It is revealed that Talsian and Nagiko, the first CEO of Atlas, both helped create Atlas for a better future for their descendants. He is placed under arrest by Ryoko under allegations of having assisted an unknowing Karin to shut down Atlas' critical systems.
Having a snakelike image, MEDUSA is a computer program built for Ishida Finance used to find debts around the world in countries whose CO2 emissions and carbon credits are not equal. Using these "debts," MEDUSA generates vast amounts of money for Ishida Finance through various manipulations of the carbon market (similar to the stock market). MEDUSA is originally believed to be the only program in the world that can perform these manipulations of carbon credits, but it seems that there are other programs similar to it operating across the globe. MEDUSA is kept securely hidden in the Marshall Islands and is protected by a typhoon created by a weather satellite.
Akihabara A group of elderly Otaku brokers who reside in the Black Market of Akihabara.
