Initially it focuses on "rebuilding the world" after its devastation by the virus that humanity is facing, the second "Black Plague". By name "Closure": a virus that threatens the skin and the they melt of internal organs, turning people into empty hooves emerged and killed 15% of the world's population.
Soon after, an organization called Propatria decides to "dominate" the planet - obviously, without using these words. A division comes to be made in the world: there is the Gnosia part, where Propatria acts, and Agnosia, which does not have the influence of the organization. By having constantly seen the struggle of revolutionary groups striving to achieve an egalitarian world against Propatria, but in the course of the manga the virus evolves into Disclosure ("revelation", "divulgation"), completely changing the focus of the manga. In fact, the very name of the virus refers to a given revelation, as if the author were telling his reader that the focus has changed. Eden was based on Gnosticism, a doctrine, as a religion. From Gnosticism I have taken much of the plot, which follows the idea of a "corrupted" world, which will never be good for human life. It is as if humanity needs to search for a better world, and all this is introduced by the Closure virus, which devastated the population as a prologue to the end, followed by Disclosure, which opens the door to humanity's "salvation".
In this scenario, Eden really begins to tell the life of young couple Ennoia and Hanna, one of the first to be discovered as immune to the epidemic, they deal with it and their internal conflicts over the uncertain fate of humanity. The story, however, focuses on the second generation, where we are introduced to the son of the two and also the protagonist, Elijah. An intelligent boy with knowledge of the world in which he lives, but still very naive, naivety, that will not last long, since among armed guerrillas, mercenaries, prostitution, drug trafficking and much death the young person will discover (with the reader) that the future is not So shining.
The aspect of the manga that most catches attention at first sight is the maturity of the plot. In less than two chapters are discussed or mentioned topics such as religion, homosexuality, politics, biology and existentialism.
