Zetsuen No Tempest is based on Shakespeare's books. This is why Zetsuen No Tempest is one of the best anime I ever seen, it has everything to make it a good anime. Action, Drama, Intrigue, Comedy not much but it has it. If you want to start to see some good anime this is the one you should see, mostly if you are a person that likes a good plot on a bood somenthing intersting and Sci-ficcion you should see this.
