Fifteen-year-old Tsukune Aono is average in every way; he has no hobbies, less-than-stellar grades and he's even flunked his high school entrance exam. 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. However, he quickly attracts the attention of a number of devilish beauties including the vampire Moka, a busty succubus and even a young witch! It seems Tsukune's average life isn't so average anymore!
Both anime have similar plots to the relationship. In each case the "Man" is a unique indivdual who is the only one that can be present with the givin situation. In infinte stratos Ichika Orimura is the only man on earth who can pilot an IS system, while in Rosario Tsukune Aono; is the only male human attending the school. In both anime the relationships are very very blunt, but its worth a watch to get a chuckle in.
Both anime have a male protagonist, surrounded by girls fighting over him. The feeling is similar in both animes, tho a bit different. The hillarious situations that Tsukune and Ichika get themselves into are always embarrassing and that's what makes them funny and makes you laugh. I recommend watching both animes if you like comedy and school-like anime.
Both of these series involve a variety of half human characters who band together and become friends. They are all trying to fit in with humans by going to school and doing other human activities.
Both Inu X Boku SS and Rosario to Vampire share many similar plot points such as: They both deal with monsters in human form and their relationships, they both have a comedic element to them as well as a romance element, and they both discuss the part monster/part humans relationships with regular humans. I would definitely give one a try if you like the other. Inu X Boku SS does have a bit more romance than comedy though, while Rosario to Vampire is a little more comedy driven.
Ayumu was murdered by a serial killer – at least, he was. For after the mysterious Eucliwood Hellscythe revives him, he changes from a human to a zombie, much to his dismay. Now, in addition to being unable to die, the boy must see to the whims of his supernatural, silent companion – but things continue to get worse from there. As once Ayumu accidentally steals a magical girl named Haruna's powers, he is tasked with the embarrassing, obnoxious task of being a magical girl – err, boy – in her stead! Then with the addition of a hostile vampire ninja to his household, can Ayumu manage to maintain his new home life, fight against attacking monsters, and track down the person who killed him all while attempting to keep what little dignity he has left in tact?
Both of these anime are fanservicy comedies with monsters or other supernatural creatures. At first, monstrous females are the male protagonist’s enemies, but after battling, they end up becoming his friend and are subsequently added to his ever increasing harem! The main heroines - Yuu and Inner Moka - similarly have an air of coolness in whatever they do, easily making them the more favorable characters.
Both of these animes revolve around a guy that is completely out-of-his-element, and finds himself with a harem of otherworldly women. Both animes also involve just a bit of school life. They also involve ecchi, slapstick comedy, and some pretty interesting antagonists.
Takasu Ayako can handle anything; duels with foreign powers and assassination attempts don’t faze her. But can she handle falling in love?

Mamoru must decide how to respond to the sudden confession of love, the resulting fascination of his fellow students, and the dangers of being near Ayako. Will his own powers ever measure up?
In Both shows main heroine is a powerful being, able to easily destroy any enemies, that devotes herself to protecting main protagonist who is weak.
Also in both cases it's a romance between highly renowned lady and a commoner.
Due to his parents' work, Riku Aoba is about to transfer to Tsumugino Private High School; but it's no ordinary high school!

To make matters even more complicated, three of the most popular girls in school are falling for him. With such a busy school life, how will Riku survive?!
The main characters, Aoba and Tsukune, both share a shy and timid nature,yet end up surrounded by beautiful women. Their character design is the same and they both end up thrown into a new highschool, each very different to what Aoba and Tsukune have experienced before. Rosario to Vampire does have a more ecchi and choppy storyline, while Tokimeki Memorial focuses on the romance and plot line, if you enjoy one show you'll enjoy the other as well.
Tokimeki Memorial ~Only Love~ and Rosario to Vampire involve the main male characters taking on a role as shy personalities. While in a high school setting the characters unexpectedly get surrounded by a variety of beautiful women.
