In a futuristic world almost barren of life, mankind is confined to mechanized domed cities where A.I.’s control all aspects of life. In this world, humans are no longer born, they are manufactured in a production line; and alongside them live androids known as autoreivs. Within one of these domed sanctuaries named Romdeau lives Re-l Mayer, one of a few citizens who aren’t entirely prevented from thinking. Her grandfather's prominent position and the affection of the scientist Daedalus have left her more free will than is normally allowed, but Re-l has started to question the sanctity of the city and the citizens' perfect way of life. With mysterious beings known as proxies causing havoc and a man named Vincent causing great influence on her life, Re-l must travel outside of the city to find the answers she seeks and discover the mystery behind "the awakening".
Among the garbage dumped down from the mysterious aerial city of Zalem, a new life is found. Restored by a brilliant cyberneticist, a young girl named Gally struggles to find her own place in the world, to learn the extent of her own deadly abilities and to discover that which makes her truly human: love.
What makes a man, what makes a robot? Both of these animes are simply put: Amazing. You are simply in tears by the end. Both anime give off the feel of a star-crossed lovers theme. I am of the opinion the creators of Ergo Proxy were fans of Alita. You can see it in the artstyles and some similar situations. (The Dumpsites) If you liked on I'm certain you'll like the other.
After a random encounter with his childhood friend Hinoki, Keita finds himself in the cockpit of a powerful mecha known as a Neuroroid alongside the girl. Though he once was a typical teenaged boy, Keita now must help the employees of Akamatsu Industries as they try to solve the mystery of Algernon, a deadly affliction that causes the infected to become homicidally violent. What is Algernon, and who is the mysterious 'Betterman' who tends to show up when danger presents itself? Keita and the gang are determined to uncover the truth, by any means necessary.
The mystery of Betterman simply eats at you to figure out the meaning of everything. You are drawn in by the moments of overwhelming paranoia, the lingering notions why has algernon come into existance, why and how does Lamia transform, what does he have to do with Hinoki, and what do they all have to do with the caves in India?
While Ergo Proxy doesn't specifically deal exclusively with human evolution like Betterman does, it does have just as many things that hook you into it that are on the same intellectual level, such as references to Greek Mythology and Philosophy, Genetics, Literature, and Sociology. You can't help but wach to find out the answers to Re-L's life, who exactly Vincent is, who and what the Proxies are, what happened to Earth, and why the Cogito virus exists.
Rokuro Okajima is a small-time salaryman who is carrying documents for his company, when the ship he's traveling on is attacked by pirates. Kidnapped, he discovers to his dismay that his employers' main concern is to ensure the documents don't get into the wrong hands, even if it means sending the carrier to the bottom of the sea. Now, with his former life ruined and his kidnappers seeming comparatively friendly, "Rock" decides to join their merry band of mercenaries, and sets out with a new career to the shadier corners of the South China Sea.
In the near future, demons with the ability to fuse with machinery and infest corpses have begun terrorizing mankind. Dubbed 'Amalgams', no one knows how they are created, or where their abilities originate from. As the random outbreaks continue, the general population begins to panic, demanding protection from these vicious beasts; enter XAT, a military unit created solely to counter the Amalgam threat. Despite being a highly skilled unit, however, they find themselves hard pressed to contain the threat, let alone subdue it. To compound matters further, a new type of Amalgam surfaces that proves even more devious than the rest - one made from the human, not machine. Yet all is not lost, two of these new Amalgams - the feisty Gerd and the mysterious Blue - actively oppose the others. With the odds stacked against them, will they be able to protect mankind while simultaneously being shunned by it?
Ergo Proxy and Blassreiter involve human characters that also have a powerful alter ego inside them. Throughout the series, said characters struggle to control their inner demon, wrestling with their own humanity. If you enjoyed that plot in one, I think you will enjoy the other.
Strange things have been happening at a local high school... mysterious disappearances, strange powers and brutal murders all emerge amongst kids who, up till now, have been perfectly normal. Even the Shinigami (Angel of Death) herself has been sighted. What's happening? The answers lie in the mysterious creature known as Boogiepop...
Ergo Proxy and Boogiepop Phantom most noticably have their atmosphere in common. While it isn't the same, Ergo is told in mute, airbrushed and dim, cold colours, while Boogiepop is dominently sepia-toned and 'glowy', yet dark and bleak. Also, the two have intelligent plots and require time, patience and attention to detail if a viewer is going to get the most out of either of these anime.
