Magical Girl Destroyers

Set in a dystopian near future where otaku culture in Japan has been obliterated by a mysterious organization known as "SSC", Magical Girl Destroyers follows the misadventures of Otaku Hero—a young revolutionary who loves otaku culture—and Anarchy, Blue, and Pink, a trio of magical girls who admire him. Together they struggle to create "a world where you can say what you like about what you like as much as you like."
