Both Shakugan no Shana and Zero no Tsukaima have very similar relationships between the main hero and heroine, even their appearances and personalities are very similar. The personalities of secondary heroines are also almost identical in both animes. Both have the heroine and hero fighting side by side, with heroine controlling a stronger power and the hero acting as a bodyguard most of the time.
These anime are almost the same plot but the roles are reversed as the girl is the one summoned in Seikoku no Dragonar. Both Anime shared the same style of comedy and have great animation. If you enjoyed zero no tsukaima you will also like this. :)
