The Cartoon Hero vs. Strike Witches from Eli Stone on Vimeo.
I recently discovered this anime has helped create a RPG Game. The page with is below but requires a log in.http://www.drivethrurpg.com/product/177440/Witches-of-the-Blue-Skies
I also saw some things in this Anime that in a competent person's could make sense. The age thing could be explained by the idea that Yoshika's mother and grandmother would have to pool their magic in order to heal her friend. Also the Witch-Like Neuroi who was nice could've been the example of a member of the alien race who has become a Fifth Column like character. Of course since this anime is terrible, we never get things like that.
