I downloaded and watched this anime called "KoiKaze" (Love Wind ) My copy was a recording from the Cartoon network so it was there for kids to watch.
Koikaze is about a man that falls in love with his teen age sister!!!!!
The weird part is, as you watch you think somethings going to happen: She ends up being adopted, one of them dies, something! I mean, they can't let brother and sister fall in love and have sex can they? The answer is YES!! I can't believe that's how it ends, I can't believe kids in the U.S. saw it on a cartoon channel!
