In Japan, there is a disturbing rumor being spread that people's shadows are ripping from their bodies, never to be seen again. For one young man, the frightening nature of this rumor is just beginning to manifest in the form of a nightmarish world that he can't seem to escape from. In this place full of dark minions and demons, he and his friends fight futilely against unknown enemies, only to be brought back to the "real world" as quickly as they left it. Is this real, or a dream? Only one person holds the key to destroying and saving the world as he knows it...
If you liked the complexity of Ergo Proxy's plot, the confusing yet understandable (yeah I know it's a contradition but that's how I feel) story, the dark atmosphere, the theme of different realities and the philosophical issues examined in Ergo Proxy I think you will also like Interlude. It has an equally confusing yet clever story, a dark and chilling feel, and is deeply philosophical. Also, a high production value.
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.
Much to the annoyance of Kei, he and his childhood friend Katou have died, having been torn apart by a train. But rather than finding themselves at the gates of heaven, the duo materialize in a room full of strangers and a giant black sphere known as GANTZ. As if dying once wasn’t bad enough, the occupants of the room are then forced to embark on dangerous missions to kill strange aliens; missions that very few return from. Now, Kei, Katou, and a well-endowed friend must fight for their freedom with an arsenal of guns, high powered suits, and a very low chance of survival.
GANTZ and Ergo Proxy are about prisoners and their attempts to escape. Posing new questions with each new episode, they both keep you guessing until the end, developing strange characters on a thin balance between good and evil. If you liked the mystery and philosophical storyline of one, you would like the other. GANTZ is far more gory though and not for the faint of heart, while Ergo Proxy is slow-paced and descriptive, less action-packed and in demand of more patience.
With no speech, Ningyo relates the story of a boy who falls in love with a mermaid. Their love blossoms in wonderful places (and through amusing games), but when living in a world of prohibition, one can not daydream as he pleases: torture and brainwashing should teach the boy what reality is made of, and that does not include mermaids...
Although Ningyo and Ergo Proxy seem to have nothing in common at first sight, Ningyo deals with a topic that comes forth in Ergo Proxy: a totalitarian rule uses mind control to keep the citizens in line. The graphics might not be appealing maybe, but if you liked Ergo Proxy, check out Ningyo; it's short and the simple way the repression is pictured in it is really worth it.
Metropolis is a grand high-tech city-state populated by humans and robots alike. It is in these streets that Detective Shunsaku Ban and his sidekick Kenichi search for the rebel scientist Dr. Laughton who unbenounced to them, is developing a super android named Tima as a tool for the Duke of Metropolis. What starts out as a normal case turns into mayhem as the scientist is murdered, and the true plans of the Duke are finally revealed...
While plots in those two shows aren't very similar, cities that appear in both of them give a similar feeling (Romdeau in Ergo Proxy and Metropolis in the movie by the same name). It is worth noticing that, robots in both anime, seam to have similar social role as well as their role in the story (there is no Cogito virus in Metropolis, but still). Also there is a small similarity between Pino from EP an Tima from Metropolis. If you like dystopia shows with good animation, you should give those a try.
