You will like the other one! Both Ecchi with lots of fan service! Also both Harem with lost of girls being attracted to the main character. The main character is a guy. The guy seems weak at first, but in Ichiban Ushiro no Daimaou it turns out the main character is very strong. Also there are many exciting battles that deal with magic. Lastly both are very well scripted and have good stories. Main difference is that Rosario to Vampire is a lot funnier.

Did you enjoy seeing the relationship between our lead character and the main female love interest grow with an agonizing speed? Then look no further, this is the anime for you!
