Nyarko-san and Rosario to Vampire have a lot in common. Firstly, they are both supernatural harem anime were the guy everything focuses on is human. Furthermore, both mix horror elements with comedy to get... well, comedy. To top it of they both have a bit of fanservice. (Though, in Nyarko-san's case it's more to the characters' enjoyment.)
They are not a perfect match, mainly because their sources pf humour are very different, but I think that if you like one of them you should at least try the other.
both are boy dealing with things normal humans are not supposed to see, one is aliens, one is monsters, both have harem and comedy, with the poor boy just trying to survive from day to day
Yukinari is blessed with an clinical fear of women, commonly known as gynophobia. In addition to his mental ailment, he has the misfortune of being short and weak, making it easy for women to overwhelm him further. Even when his childhood friend, Kirie, approaches him, he immediately breaks out in hives. Thus, life is very lonely for Yukinari, until suddenly in the strangest way possible, he is transported into another world, and into the arms of the beautiful shoujo, Miharu! This time, for the first time ever, he doesn't react. Could this be the start of something special?
Girls bravo and Rosario Vampire have one major thing in commun, and that is : FAN SERVICE.
If you enjoy the fan service in girls bravo then you will love it in Rosario vampire.
Another good and at the same time cute similarity that these series share is the romance between the main characters.
Hiro Hiyorimi is a boy who moved to the city to live with his sister; but as he was walking around town one day, he sacrificed himself to protect a girl from being hit by falling beams, and subsequently lost his life. Her name is Hime, and she is a princess who has the power to revive the dead with the flames of life. In return for reviving Hiro, he must work as a servant to protect her from any harm that comes her way. Yet even though Hiro now has a partially immortal life, his flames of life must be recharged daily or he will die yet again. Hime’s life is targeted by her siblings because the throne of the royalty is at stake, so Hiro must step up as a faithful servant to protect her life at all cost!
Ever since they met, emotionless Hotaru and ditzy Mikanhave been best friends, and are virtually inseparable-- that is, until Hotaru is invited to attend a strange school far away, a school for those who have special abilities known as "Alice". Unable to be separated from her friend, Mikan soon sets out on a mission to find her. After traveling to a city far away, she finds Hotaru at last, but gets much more than she bargained for. Now, she is lost in a school full of kids with strange powers, unusual animals, and has secured an immediate rivalry with the toughest little punk in town!
Both of these animes are about a character who is transferred to a school where they feel out of place at first because the other students have magical powers and they do not. The main characters also within time gain many friends. These series are both less than 50 episodes and have great mangas if you want to continue seeing what happens after the anime.
There is a legend of an angel who fell to Earth many years ago, and was forced to marry a man because he held the key to her only way home. Hundreds of years later, sixteen year old Mikage Aya is the reincarnation of Ceres, the vengeful angel, who must now fight for her life against her family and her own twin brother Aki, the reincarnation of her past evil husband...
Ayashi no Ceres and Rosario to Vampire, although seemingly unrelated the personalities between Ceres and Aya and Mako’s vampire form and human form have similarities in the characteristics they portray. The transformation has a more mature attitude and seems to be more capable all around while untransformed there is an innocent girl in place that relies on others for help.
