Aired: Oct 6, 2016. In September 1944, allied forces led by the 501st Joint Fighter Wing "Strike Witches" successfully eliminate the Neuroi threat from the skies of the Republic of Gallia, thus ensuring the security of western Europe. Taking advantage of this victory, allied forces begin a full-fledged push toward central and eastern Europe. From a base in Petersburg in the Empire of Orussia, the 502nd Joint Fighter Wing "Brave Witches," upon whom mankind has placed its hopes, flies with courage in the cold skies of eastern Europe.
Witches are individuals with special powers like ESP, telekinesis, mind control, etc. (not the typical hogwart and newt potions). Robin, a craft user, arrives from Italy to Japan to work for an organization named STN Japan Division (STN-J) as a replacement for one of STN-J's witch hunters who was recently killed. Unlike other divisions of STN, STN-J tries to capture the witches alive in order to learn why and how they became witches in the first place.
Alice believes in magic. With all her heart, she believes that magic is possible and that it can be used for good deeds and fun games. But suddenly, she finds herself transported into another world, ruled by a mysterious elite of witches - and these witches don't seem to be in it for the fun. They're hard at work capturing sprites, the native magical beings of the world, and forcing them into slavery. Once Alice realizes that her new surroundings aren't just a dream, she sets out to change things.
After the losing of magical ability to become witches, they once again become them. But, now they have to go through tests from the Witches of the Witch World. They also meet a new member, from New York, U.S. comes Momoko (the yellow Ojamajo).
