User blog comment:Golden Bear92/My thoughts on why Zero no Tsukaima needs a 5th season./@comment-121.54.32.141-20130502052410

Want an honest answer? Noboru Yamaguchi, the author of Zero no Tsukaima (light novel) died last April 4. He wanted to work on it further, but he just couldn't anymore... he even said that he would at least finish the series "No matter what," but his condition refuses to work with him. He even let the anime's production team decide on the story's ending if something were to happen to him.

Sure enough, a season 6 might've been made from the remaining novels, but as respect to the author that brought us this wonderful show (and to prevent giving the viewers cliffhangers and not-so-legit stuff) they decided not to dwell on it further...

Let's not disrespect these people who worked so hard on making this anime possible- and also honor Yamaguchi's creativity. That's the only thing we could do as loyal fans.
