Moetan is a manga series in Japan aimed at Otaku that's purpose is to teach English while entertaining the reader with loli moe fanservice. For those wondering, moe doesn't necessarily have to do with either loli or fan service, but such is more often than not the case. The Moetan girls in particular have become popular with Otakus because of their lines of books & scantly-clad figurines.
Well anyway, there's now going to be an anime series based on Moetan that'll have the same goal. Teach English with fan service! It's not really even good English, keep in mind. But American anime fans should have fun watching this series online when it comes out to make fun of the English that'll be used (& also drool over the girls, of course). The series is set to premier this July in Japan.
