o right yeah so most of the manga ive watched has had some sort of ecchi quality to it and tbh i think it adds humour to the anime.
ive just finished watching zero no tsukaima and i thought it was good, the story was a fresh twist on the harry potter esque magic school and brought a lot to it. as well as the ecchi and harem aspects of kisrche, louise and siesta with saito the main char 9/10
only gripe was that it could of been longer maybe more smaller storys inside it and going insted of 13 episodes to 20ish. cheers for suggesting that1 btw!
