When Sorawo and Toriko undertake another foray into the Otherside via a Shinjuku pub and lose their way, Kisaragi Station awaits them. The unarmed pair gets into trouble, only to be saved by a mysterious band of soldiers. As the girls soon discover, the soldiers are American marines stationed in Japan who found their way into the Otherside from their Okinawan base and have been making camp at Kisaragi themselves, unable to find a way home.
