Following the false maestro incident, the chess club decides to unwind and enjoy the beach. However, trouble won't allow them such reprieve. A trio of Desperados arrive, dragging Mimoko, Iori, and their friend, Carol, to London where Mimoko is held hostage by the infamous Fairy league, a radical chess league led by the queen of England, Heather Fairy, whose goal is to implement fairy chess supremacy worldwide. Okisato and the others begin chase, but find their path blocked by the Desperado's Prof Manfred von Skaberghast, one of the original inventors of the DESPER as well as someone Okisato has a history with. To make matters worse, Desperado enforcer and kaiser of the German Empire of Prussia, Red Reaper von Richthofen, has London in his sights, and plans to launch a one-man invasion in order to hunt down a specific target. How will Okisato and co get out of this pin?
