Oh, would you look at that! It's another anime that involves monsters and one lucky guy who's just smothered by all the attention. Rosario + Vampire follows the story of a high-school student who goes to a boarding school where students are monsters learning to co-exist with humans. Surprisingly, most of these 'monsters' are hot girls!

If you haven't yet heard of this anime, then let me just say that this is one of the best, if not the best, fanservice anime that you'll ever see! Just like Interspecies Reviewers, High School DxD has the monsters, the comedy, and most importantly, the sizzling hot anime babes! It's an anime series that you don't want to miss!

Toujo Basara has really got it good in The Testament of Sister New Devil. Aside from having two smoking hot step-sisters, he's got every other girl coming after him. Plus, if you're looking for mystical beings like the ones in Interspecies Reviewers, you'll be surprised to know that his sisters are actually demons. Didn't see that one coming, did you? 

You've got out-of-this-world beings mixed with Earthlings. Hot celestial babes flaunting over one guy. Judging by those two statements, it's enough to see how To Love-Ru is similar to Ishuzoku Reviewers. Join Rito Yuuki in this rom-com anime full of slapstick humor, sexy girls, and outrageously lewd moments!

Now, this anime doesn't necessarily have male protagonists. Still, it's got all the lewd and crazy moments that you could expect from Interspecies Reviewers. Mamori is a virgin who stumbles upon an island and she must compete in battle. The twist is that she can only activate her powers by having sex with other girls.
