Prism Ark

This kinda reminds me a little of zero no tsukaima. Because of the draw style and somethings that are the same: a magical school, a girls who doesn't like the boy that mutch (at the start). So it's worth watching if you like one of these to watch the other one 

they give the same kinda of air and presense - both main guys have blond hair, same happy attitudes, they have almost literally the same past. both have that medieval feel, with swords and all, though EG also has guns (but if gives this kind of final fantasy feel) both have this girl thats a bad guy that joins up with the main guy. both the main girls are super special for the plot and for their status. 

both have that medieval/fantasy/magical power kind of stuff to it. basically the setting is pretty much the same both have one regular guy with lots of potential meeting royalty and being the "hero" the animation, the characters and how they look are very similar one of the main characters are also a tsundere 

the female characters are pretty much the same. can't decide on feelings etc. the boys both act the same cheeky etc. its a good anime check it out. another cool thing as that they are both stronger so its a really good anime if u have time 

overly complex/confusing plots, political/society affairs, essence of darkness, drama, romance, action, fighting. extremely similar feeling and plotlines 

Magic, big enemies, stupid plot, arrogant lead character and a love plot. Both have that. 

They both have a magical genre and an adventure to save the world, except thatthe main characters are opposite genders. The stories start off with no one knowing anything and as the story progresses, the characters change and find out more about the past and such. 

Both are action fantasy with lot of comedy. Also, both have male student who has great power and must fight in his 1st school day.
