Baruto no gakuen

Many of the German soldiers in the movie were not Germans, but Hungarians, Russians, Norwegians, Swedes, Americans, British, and Canadian people, many of whom were students from Universities around the Kansai area, like Osaka and Kyoto. Thus, when the soldiers were going to shout and make noise, only the German people and those who could pronounce perfect, or good enough German, were allowed to speak.
