The story's mainly about a high school teenager whose main purpose in life is to change the world into a safe place for his sister Nannally. Fighting against the government of the mega country Britiannia, the main character takes up the persona of a hero/villain/robin hood like person and utilizes the power of his geass, the power of the kings, given to him by the unknown being CC.
Story 9/10: The overall story was great, and is very effective at hooking the viewer and making him or her want more. I was tempted many times to read the wiki because I felt like the anime moved too slowly for me, but still kept watching because I knew I would regret missing some of the small details that the writers threw in. I love how the writers keep the interactions between the characters very tight, and more than once had me yelling at the screen because once again two of the main characters refuse to see each other.
Art 7/10: The character design for me seems to be a little more realistic than I would like, but is still great.
Sound 8/10: Standardish anime music. Nothing outstanding.
Character 9/10: The characters in the story all have their own reasons for doing what they do, and made me support them no matter which side they were on. Kudos to the writers for creating such amazing characters. However, there are a few people whom I feel contributed little to the anime, but nevertheless are in it. Though they don't detract too much from the main story, I wish the authors focused more on the main characters and the realtionships/struggles they face.
Enjoyment 8/10: Enjoyable, but still somewhat disappointed at some parts in the anime.
Overall 8/10: This is a great anime to pick up for anyone who enjoys shounens such as Naruto. But for the diehard shoujo fan I am, it's decent, but not chair gripping worthy.
