No. 6

I absolutely LOVE this anime! Only 11 episodes, but they're episodes of total AWESOMENESS! I recently finished this anime in my trip to Newport, California. This anime is about a boy named Shion who lives in a Utopia of paradise, but meets a fugitive named Nezumi (Rat). He gives Nezumi shelter and food, and his genius standard in this city, No. 6, was taken away. One day, as he saw a dead body in the vushes, and a weird bug that looked like a wasp came out of what seemed to be an old man's neck. Later, his job associate started becoming old, and when dead, a wasp came out. Accused of murder, Shion is being taken to the Correctional Facility, where no one came out alive. Nezumi rescues him, and they live outside of the Utopia No.6. Later some other stuff happens, which cannot be missed.
