Hexenjagd is a resistance group formed by former researchers that defected from The Organization due to the danger that they posed to the world. Hexenjagd is German for "witch hunt", making them aptly named.
Their goal, other than seeking to bring The Organization down, is to exterminate magician's, beings that are implanted with alien creatures that will eventually hatch and prey on humans. In particular, they seek to kill Kotori, a girl who hosts a creature known as a Grane that is said to be capable of exterminating all life on the planet when it hatches.
