Oh, Mai-HiME is really cool -- well, I think so. ^_^ It's a magical girl adventure with a trio of awesome main characters -- a responsible older-sister type, a badass cool silent type, and a childlike incredible fighter type. They're all awesome in their own way, and there's also an incredible cast of minor characters too. (My favorite characters are Takumi and Akira, the little brother of the main character (Mai) and his ninja roommate. ^_^ They're hilarious.) ...needless to say, I really like the series.

And Host Club definitely deserves the recommendations, cos it's hilarious. ^_^
