If you liked the Zero no Tsukaima anime, the Anime-Planet community thinks you'd like:
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.
The eccentric Suzumiya Haruhi wants nothing more than to meet aliens, time travelers and espers… but she’ll have to settle for the everyday Kyon instead! Along with the mysterious Itsuki and the vacant Mikuru, the duo forms the SOS Brigade – a club whose mission is to discover the mysteries of the world. Armed with a razor sharp wit and a skill for manipulation, Haruhi will stop at nothing to have fun at all costs, even at the expense of Mikuru’s dignity!
Both stories revolve around a girl who is looked down upon by her peers and find enjoyment with the main guy character. Both are in school settings, even though Zero no Tsukaima is set in a school of magic, mysterious and supernatural events occur in Suzumiya. Many of the characters share the same personality traits as well. Louise and Haruhi are bossy. Both Saito and Kyon are forced in some sense to be with the respective female protagonists.(FYI, not in forced in love, I couldn't find a better way to word this)i Also minor characters are very similiar too. Overall, both are very good and comedic animes.
Yohko is nothing but ordinary. Throughout her life she has been considered an outcast, especially with a hair color not native to many in Japan, bright red. Things change for Yohko when a mysterious man named Keiki arrives and claims that she is his empress. Yohko and two friends are then taken through a vortex, and then abandoned.. in a world of demons and magic.
Touma Kamijo's right hand has the ability to nullify any form of supernatural power, whether it be magical, psychic, or divine; he lives in a city populated by students with these powers. Yet unfortunately for Touma, his arm also seems to nullify good luck. Despite his bad luck, the boy tries to stay out of trouble and just live out his life, trying to be the "good guy" whenever he can; but trouble enters his life one day when he finds a young girl hanging on his balcony. She turns out to be a nun of the Church of England, bearing the Index-Librorum-Prohibitorum - a collection of 103,000 forbidden texts, and as a result has a number of people after her. How far will Touma go to protect his new companion from her pursuers?
Both have main characters that get thrown into a world they didn't know about by a girl that is not afraid to get violent if they think he is being inappropriate (the main difference being that the main character of Zero no Tsukaima usally is being inappropriate), and they both end up protecting the girl that turned their world upside down. Their feel is a little different, but if you liked one the other is worth checking out.
Sunao Konoe has just transferred to a new school and quickly makes new friends in the flirtatious Shinichi, loud Kinu and other classmates, but what she really wants is to form a theater club. There’s just one problem: the student council has to approve any new clubs, and the group is led by Erika, an arrogant girl who refuses the request! With distractions such as her childhood friend Leo, part time jobs and Erika’s outlandish challenges standing in her way, will Sunao ever manage to form the theater club?
I think these two anime do have some things in common. First I believe these two anime share the same atmosphere. Second the female lead character in both anime, are in some ways similiar. They are both hard and cold but later soften up and become loving. Although ZnT has that thing more than Tsuyokiss. I also think the art style is a lot like each other.
