What is rosario plus vampire 7 about?

Answer 1

Rosario Vampire is About a Boy named Aono Tsukune going to a Monster school called Yokai Academy, and he meets this girl named Akashiya Moka. Moka isn't a normal girl either, she is a vampire with a rosario (not a coincidence if you compare it to the title of the anime). Anyways Moka has two personalities outer & inner. Tsukune gains this vampire's trust and many other monsters like Mizore a snow woman, Kurumu a succubus, Yukari a witch, and Ruby another witch.

Later on in the anime it becomes a harem and all the names mentioned above are involved.
