Zero no Tsukaima F

Very similar feel but not exactly like each other. Although Seirei Tsukai isn't as good as Zero no Tsukaima, both have very similar genre and involves a guy who's strong and starting a harem. 

-Tsundere heroines -Main boy character with same kind of special power -Same aspects -Comedy, Magic and Romance genres -There is a character who is or dresses up as a maid in both anime 

Does two animes are to similar. Both protagonist come from modern world to medieval one than they both become servant of noble girl and they both eventually become heroes they both start to hawe filings for that girl but they refuse to admit it and both protagonist are nearly same caracters as well as that girls both protagonist are suraunded with prety girls that are in lowe with him both animes are Action/Comedy/Romance/Harem and both are very good animes. 

-Tsundere heroines -Main boy character with same kind of special power -Same aspects -Comedy, Magic and Romance genres -There is a character who is or dresses up as a maid in both anime 

Same main character transfer in a fantasy world. + love story, - mmo.  

Both the protagonists Touya and Saito have a Dukedom of their own and are masters of a castle where many women who love him are living with him. The difference is that in The Familiar of Zero they fight for his affections whereas in In Another World with my Smartphone, they are on the same page and want to share him. The concept of a unique magical world is also common to them.  

- Both have female masters, Louise and Nanami, who are protected by their male familiars, Saito and Tomoe. - Both Tomoe and the Pope have the same seiyuu, Tachibana Shinnosuke. They are also kind but ruthless. 

A guy gets taken in by a wealthy girl that they serve by protecting her from danger, and they eventually develop a love interest for eachother. 

They both have males that are lucky having all the girls like them.... both males use swords to protect the girls :) ZnT = fantasy while IS = mecha Zero no tsukaima only has more romance while is depicts harem 

Louise and Aria have a lots similarities - Pink hair - Tsundere - Short - Take main male chara as slave - same voice (Louise & Aria) by Kugimiya, Rie 

The serie is different, but the way both authors combine romance, fantasy and comedy with a bit of ecchi really both are a must watch series ;P 

Both animes have a tsundere theme (love/hate relationship) between the 2 main characters. Basically, the only difference between the two animes is that Toradora takes place in a school setting. 

Almost the same other than the fact the roles are reversed Luise = Kusanagi Saito = Erica Both swordsmen/woman protect the mage Zero no Tsukaima is funnier in my opinion 

Both have a similar plot about magicians in a significant magic wise. Even the clothes of a few pristess are the same on each one, but at Zero no Tsukaima it's like a tribute to To Aru Majutsu no Index. 

>Those series are actually different, but there is one thing of Zero no Tsukaima (ZnT) that reminded me Code Geass (CG): the story start in a small place, like a school/magic accademy, and it develops throught the whole world, and so, if you appreciated that developement I'm pretty sure you will enjoy both series. >By the way, CG is much more serious, there is poor fanservice, the story is kinda a mindfuck (oh god, I loved CG so much), and the mai character is a complete badass. Meanwhile ZnT have a bright atmosphere throught 90% of the episodes, ofc there are some good touching moments, but is more based on a slow develoment and high ecchi/funny parts then on a solid story. >Personally, I think that CG is worth a 10/10, while the whole ZnT is a 9/10 (for me, as I said), while the very last season of ZnT is a bit better then the others. >I hope you will enjoy both. >CG: War, tactics and mecha. ZnT: War, ecchi and maho... ah no, magic! read more
