In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
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 Zero no Tsukaima and Rosario to Vampire contain the idea of magic as a major theme (for Rosario it's more mosters, but there is magic too). They also both have a girl of a higher class (a vampire) who likes a boy of a lower class (a human). This is a bigger idea in ZnT. Also, the girl vampire always gets jelous when the human that they like has another girl that likes him.
Both are about the male lead ending up in a 'magical'/supernatural new world/school and meeting a cute girl.
They are both ecchi harem romance action comedies. Both animes include harem, but there is never 'distraction' from the main male/female leads, and rather the 'harem' works at resolving each new plot event.
Themes of both include class division (nobles/commoners monsters/humans), and a consequent breaking of barriers. Action for both are mainly 'fun' action sequences that are mostly absurd than serious.
These anime are similar for several reasons. They are both harem comedies, they both have some fan service (Although RtV has more), the male lead is a human in a world centered around magic, and they are both centered around class division (or species division). I think anyone that liked either of these would be able to enjoy the other.
If you liked Zero no Tsukaima then you would really like Rosario + Vampire or the other way around.Both have very powerful and high class female lead who falls in love with a nonpowerful low class male lead.
Aoi Sakuraba, heir to the Sakura department store, has only one thing on her mind-- her beloved. Betrothed from a very young age, she has been in love with him, Kaoru Hanabishi, ever since. After Kaoru left his family, their bethrothal was nullified. Aoi sets out to find him. Will they be able to stand against the barriers that will try to keep them apart?
Although one takes place in a fantasy setting and the other is not, I think both Zero no Tsukaima and AYA offer a good amount of rich characters, romance, comedy, and drama. I strongly recommend watching both.
In both AYA and ZNT the main story revolves around an impossible love story, as the main characters' families are against such a relationship. Furthermore, both stories have a good mix of comedy and ecchi scenes. If you loved one series for these reasons you will like the other too.
Ai Yori Aoshi and Zero No Tsukaima are harem anime that depict love in difficult situations. Because of these situations there is a lot of similar comedy involving the main male characters, Kaoru and Saito, as they interact with unsuspecting female companions.
Once upon a time, two brothers passed the happy days of their childhood by studying alchemy, which is governed by the equal transfer principle: an eye for an eye -- you can't get more than you give. But these brothers tried to defy that law, and a horrific accident resulted. Now, the older brother, Edward, is called the Full Metal Alchemist because of his metal limbs, and the younger, Alphonse, is a soul without a body, trapped within the confines of an automaton. Together they search for the power to restore themselves, to find the lives they lost so long ago...
Both of these great anime are about different sorts of magic. They are both very humorous and have similar character characteristics. Both of these anime are funny and i would strongly reccomend them. I enjoyed both of these anime very much and I think you will too.
Plotwise... character wise... even genre wise, these anime don't appear very similar.
However, during some parts Zero and especially the end of FMA, reminded me a lot each other. Both deal with the idea of "Earth" and how there's another world out there. I enjoyed how they made the connections between the current world and Earth (especially during WWII) and it's weapons.
If you like these ideas in anime, then you'll definitely enjoy both of these!! They're both fun in their own ways with a hint of humour and I believe the girl that plays Al is the same voice as Louise.
Both of these animes take place in a world full of magic where impossible became possible. If you like watching stories which are owerflowed with magic and humour you'll for sure like the one I reccomend.
The Kawahira family specializes in dealing with troublesome spirits with the help of inukami, strong dog spirits that take human form. Members of the family are expected to make pacts with strong inukami in order to fulfill their duties, but their family has a black sheep: the perverted Keita, who charges people for his help. His inukami, Youko, is dedicated to make Keita completely hers. Her favorite form of punishment for him when he strays is teleporting him into the city completely naked. He's been arrested for indecent exposure so many times that he's a jailhouse regular, and is considered an outcast by his family and normal society; yet an inukami of the highest caliber chose to be his partner?! Is there really more to him than perverseness?
Like Zero no Tsukaima, Inukami! has similar plot elements of a perverted but kind-hearted young man paired with a beautiful magical girl who wants him to look only at her and punishes him thoroughly when he doesn't. It is an outrageously funny show with the connecting thread of the relationship between these two.
Both series contain two main characters that are together in order to fight evil. There is a lot of magic, demons, evil and ... love in those anime too.
Both series have a strong and also kind of aggresive heroine that allways seems to be a bit jeaolus of the protagonist, wich leads to alot of funny situations.
Both series also contains the same kind of comedy and they both contains some romance that sometimes seems to lead nowhere.
Upon trying to save a friend from bullies, Shibuya Yuuri finds his head in the unlikeliest of places -- the toilet. Like a flash, Yuuri is then inadvertently sucked in, transporting him somewhere else! In this unfamiliar world of flying skeletons and magic, he is informed by a group called the Mazoku that he is to be the next Maou -- ruler of the kingdom! With harrowing and embarassing situations ahead, can our hero swallow his pride and lead a war against the common people when he can't even tell the difference between a slap in the face and a marriage proposal?
Both Kyo Kara Maoh and Zero no Tsukaima revolve around 'normal' guys who find themselves suddenly plopped into another world without warning. A world where magic is the norm and the rules of aristocracy must be learned. Both series have very similar comedic styles, and KKM's Yuuri and ZnT's Saito are constantly tripping up as they try to navigate their way through the new and sometimes bizarre customs. Yuuri and Saito also share a 'just do what's right' attitude that sometimes conflicts with the established patterns of the aristocracy... and both seem to discover that there is more to themselves than they knew. If you had a good laugh at Zero no Tsukaima, you should definitely give Kyo Kara Maoh a try.
In both Zero no Tsukaima and Kyo Kara Maoh an average guy is transported to another world where he must learn all of the rules of the land. They are both very funny anime that will make you laugh. If you enjoyed one or just want to watch something new I recommend both of these anime.
Both of these series share the main similarity of an everyday guy being transported into a different world and having to come to terms with a new role in life. Yuuri has to come to terms with being the Demon King of another world, whereas Saito has to deal with becoming a slave. Both of these series show the development of the main male characters learning to accept this new world and not only finding their true place in these worlds but also gaining the desire to do the best they can in their new positions.
