Zero no Tsukaima: Futatsuki no Kishi

Boy teams up w/ loli girl, fall in love, same sieyuus for main char, but this is more serious 

The main characters are very similar in their personalities and their treatment of the main character but toradora doesn't have the same fantasy factor 

Both have the harem elements all over. If you just love watching Kugimiya Rie (seiyuu) and Hino Satoshi (seiyuu) in action together, definitely pick up both. 

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.

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. 

Akane and Louise are both violent girls. Ranma and Saito are both popular with girls. The funny thing about Ranma 1/2 is that it's full of trouble. It's the same thing for ZnT. Plus, ZnT can be considered as a romantic comedy too, I think. The only difference is that ZnT is a tiny bit more serious than Ranma 1/2.
