No. 6- a utpoia for those who love their city and never question it. A place of exile and terror for those who dare speak a word against it. Created to be a haven after the wars destroyed most of the world, those in power grew too hungry for power, and try to harness the power of a forest to try and revive the world.

This anime has some good ideas, but suffers for its legnth and attempt to balance character development with plot development. There is great build-up for the first 4 or 5 episodes, with the meeting of Nezumi and Sion, the clues that not everything is as it seems in the city, the way Sion sees life for those around him outside the place and his determination to save the people in the city. Unfortunately, the relationship with Sion and Nezumi gets rushed because they have to move the plot along, and the plot suffers because they spent time on the relationship.

The great build up in the beginning all goes to waste in the second half. Who or what exactly is Elyusia? How was it determined that nothing of Safu remained? Why would anyone program all the computers to destroy themselves if the main computer was gone (by far the dumbest programing mistake ever)? And it was topped off by the most ridiculous and blatant revival scene ever.

On the other hand, that finale also delivered in terms of action, explosions, emotional punches, and the wall, which is why I'm still rating this over a 5. It might not make up for everything wrong with it, but it was the consolation prize for having watched all of the show.

Violence/Gore: People are killed in many ways. Some age rapidly and turn into mummies. Some are shot. Some are blasted by... sonic waves from a tank. However they are killed, blood does spatter and some bodies are shown. This also goes for some Holocaustian horrors- nothing says more about what people think about you than being dumped into a pit of dead and rotting bodies to die. Thankfully, this isn't lingered on, and gore isn't explicitly shown.

Nudity/Sexual Content: When Sion takes in Nezumi, there is a scene where he's changing his shirt. During his fever and near-death there is undetailed nudity.

Problematic Theological Issues: They were after a spirit of the forest. This spirit is apparently one of a giant bee (don't ask, it doesn't make much sense in the anime either), and that spirit can bring back the dead and heal people. This is also a shounen-ai title- that is, the two male leads are in love with eachother, and there are two kisses shared.

Other Problematic Themes: There is some swearing, nothing stronger than the b-word. It's suggested that Rat prostitute himself, and the Dogkeeper is used as sexual bait for a high-ranking official. There is some ambiguity as to whether the dogkeeper is a boy or a girl (personal opinion based on scenes from the 10th episode- girl, attempting to disguise self as a boy).

While the details have been covered very well, I do want to emphasize that the relationship between the two main characters may be troublesome for some. Yes, they share two kisses, but they didn't seem really romantic. Also, nothing further really happens between the two characters to raise eyebrows. In fact, the whole relationship is up for debate on whether it's really romantic or just a very deep friendship in trying times. After all, both characters owe their life to the other. Thus, just use your own discretion when it comes to this.
