His parents have managed to enroll him in a school, but it's no ordinary school! Tsukune will be attending the Youkai Academy, a place where monsters learn how to co-exist with humans! As the werewolves, vampires, witches and other monsters are required to retain their human forms, Tsukune - the lone human - is able to avoid their bloodthirsty gazes.

It seems Tsukune's average life isn't so average anymore!
While visiting his hometown, junior high school student Michishio Nagasumi's life was changed forever when he nearly drowned. Though he was saved by a mermaid named San, there’s a catch -- her family is part of a merfolk mafia, and they abide by a strict rule: If a mermaid is discovered by a man, either he or the mermaid must die. That is, unless the man marries into the family! Faced with such a decision, Nagasumi can only oblige their customs and become a "happy" newlywed. Now, with a new school year around the corner, Nagasumi must find a way to deal with his new bride, keep her true nature a secret, and most importantly, escape inevitable death at the hands of San's over-protective father’s gang!
Both of these anime involve a boy that gradually finds himself surrounded by supernatural women. The main girl is rather ditzy until she has to defend the people she cares for. With others vying for the guy's attention, school life, and trying to keep the girls' powers a secret, these anime are pretty similar.
Sakai Yuuji thought he was a normal high school student, until one fateful day when time stopped. Watching in horror, he witnesses a monster devouring the "frozen" people around him; but luckily for Yuuji, he is saved by a sword-wielding red-headed girl that calls herself a "Flame Haze". The girl informs him that he has been dead for some time now and that his current self is merely a replacement for the human that he used be while alive. He is, she says, merely a torch whose life will come to an end when the blue flame in his chest ceases to burn. After this rude awakening, Yuuji realizes that he is able to see the flames of life in other "torches"; and after discovering that a friend of his is also a torch -- and her life is burning out faster than his – he gains the courage to live out the rest of his life with meaning. Will Yuuji be able to find his place in the world before he ceases to exist?
Both series tell a story of a pathetic boy wo is protected by a girl through his life. Additionaly they fight demons. If you like that kind of stu there is a high propability that you will like the show I find similar.

According to Sugata’s calculations it’s set to pass above their town at midnight, and sends Tomoki to check it out. Little did Tomoki know that at that moment, a scantily-clad angel would fall from the sky! Calling herself a pet-class Angeloid named Ikaros, she promises to fulfill Tomoki’s every wish.

If you loved Rosario to Vampire's school for famous monsters concept, then be prepared to have your mind blown by Soul Eater. An exponentially better series, Soul Eater takes classic monsters, and puts a fresh anime twist to them, packed full of comedy and action.
Since long ago, the wolf goddess Holo has honored a contract to bless the rural village of Pasloe with fertile harvests; and in return she has been celebrated and worshipped by the villagers. But as mankind advances, the people have begun to take command of nature for themselves and have made their own god to worship. Holo finds that she is paid little more than lip service, if not outright mocked; and considering the contract annulled, she takes human form and enlists the aid of a passing merchant, Kraft Lawrence, to return to her home in the snowy forests to the north. As they journey together, Kraft finds that he has plenty to learn from this capricious god, and she from him as well.
Both series have a supernatural aspect to them eventhough in Rosario + Vampire it's a little bit more evident with the setting being in a "school for monsters" while the main supernatural event in Spice and Wolf is Horo.
Also, both have a romantic side to them, and a totally loveable female main character! Moka from Rosario+Vampire is very sweet, and we are constantly watching what will happen with her relationship with Tsukune. In Spice and Wolf the same thing happens with the relationship between Horo and Lawrence. Horo is also a sweet character, as well as a very whitty one! I think if one of them gets hold of your heart the other one will do so too, be it because of the humor, sweetness or sexiness.
Both series are lots of fun! I think that if you enjoy one you'll definately enjoy the other.
