I highly advice you to watch this. Interesting scifi anime.
The story takes place in a future where Earth and the Moon are in conflict. The world is ruled by an AI named Sapientia. To maintain peace on Earth, criminals and polluters are sent to the Moon, creating a poor and rebellious colony. We follow Jack, a young man who joins the Earth army to avenge a lunar rebels after a terrorist attack, but who soon discovers that reality is far more complex.
