If you liked the Zero no Tsukaima: Princess no Rondo anime, the Anime-Planet community thinks you'd like:
Ranma, raised to be a man among men, has a bit of a problem: he is half woman! While training in China he fell into a strange magic spring at Jusenkyo. Now, he is eternally cursed to change into a beautiful woman whenever he is hit by cold water, but that may be the least of his problems; his father has betrothed him to marry! There's never a dull day for Ranma as he attempts to find a cure for his curse, train to become stronger, and grapple with the fact that half of himself may be more feminine than his fiancée!
Both have a focus on a developing relationship between two people who are stuck together through circumstances beyond their control and who are trying to understand how to get along with each other, and if they even want to get along in the first place. In both shows, the female protagonist is violent, exceedingly jealous, and constantly pushing away the male protagonist despite the fact that deep down, they know they want to be with him. Both male protagonists have a series of women who fall in love with them and chase them down at all costs, often resulting in awkward situations and anger and jealosy from the female protagonist. In addition, both male protagonists develop a strong desire to protect the female protagonist, despite the fact that the female protagonist could probably take care of herself. And althought Zero no Tsukaima takes place in a magical world, while Ranma 1/2 takes place in modern Japan, both have strong elements of magic and fighting that are essential to the plot. The humor, romance, magic, harem, and fighting elements make these shows a natural pairing. If you liked one, you will probably like the other.
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 These Anime are very Similar about a Girl who hates a guy but grows to like him. and they both incude some really good fight sceens. I rate both of them as very good and well worth the watch.
The members of Bal Masque have left the city after their last clash with the Flame Hazes, and as a result the Flame Hazes and their allies have been living a peaceful life; that is, until Yuuji and Shana encounter a Tomagura with the ability to create imaginary worlds from dreams. During a fight against it they learn that Yuuji has a Keeper within him protecting the artifact that grants him life: Reiji Maigo. Meanwhile, in school, new and suspicious students and the interest of fellow classmates have made Shana and Yoshida’s relationship even more complicated. With girl troubles at every turn, Yuuji must continue his training so that he may protect Reiji Maigo from the hands of Bal Masque.
The use of magic, swords, and beating up on their boo. Both of these shows consist of similar characters, an even have the same person playing the voice over of the main characters. If you liked this anime, you will surely like/love this one as well.
Yuuji and the Flame Haze Shana have thwarted several of the Bal Masque’s evil schemes, but the lives of a Flame Haze and the holder of the Reiji Maigo are never simple. While rifling through a pile of objects, Yuuji finds what appears to be a telescope; but after looking through it at Shana, an unfortunate side effect occurs: they switch bodies! Now inhabiting the flesh of the other, the two must stick it out until they can change back. What other adventures await the supernatural pair?
Both animes have the same basic elements. They are both very well done animes and if you liked/watched either Zero no Tsukaima or even Shakugan no Shana, you will enjoy watching the other.
And if you haven't watched either I highly suggest that you do, especially if you enjoy a romance anime with action, magic, and cute spunky tempermental heroines.
Rhiannon is the fair and gentle daughter of a village chief. Unfortunately for her, she's also exactly the sort of maiden who is needed as a sacrifice to wake the Demon King Arawn from his thousand-year slumber and is soon kidnapped for this very purpose. However, when Arawn is summoned, he decides to spare Rhiannon's life, instead killing her captor and freeing her from mind control. Taken with his kindness, Rhiannon immediately decides to marry the Demon King, making him the new village chief. All of this is bad news for Rhiannon's protective but hot-headed brother Arthur, who must now pledge his knightly service to his new Lord, Arawn. Together the three of them must journey and together they must fight, encountering new friends and new foes along the way.
Both main characters are summoned from another world/dimension. They both are sword users but in tears to tiara the main character is highly skilled from the start. They are both harems with many different women falling in love with the main character, but Zero no Tsukaima is more open about that. If you like adventure, wording fighting and magic fighting either one is a very good choice.
