Reiji Arai just wants to spend his days watching anime, reading manga and light novels, visiting the local maid cafe, searching for the newest anime figurines, and watching professional wrestling. Imagine his surprise when he wakes one morning and finds that he and his roommate have been transported to an alternate version of Germany which isn't too different from ours with one exception - this world is a matriarchal society, and the male population's primary use is manual labor. In order to achieve his goals and to appease an omnipotent being that is battling boredom, he must compete in and win a global professional wrestling tournament. But, there's a catch - only women are allowed to participate. So, what's a guy to do? Become a girl and hope for the best!
