Shimazu Toyohisa, a samurai from the historical Battle of Sekigahara, was moments from death when he stepped through a door. Transported to a world both like and unlike his own, he finds himself in a new war-but he is not alone. By his side, Japan's most notable historical figures Oda Nobunaga and Nasu no Yoichi will join him in this new world at war as they take on the role of "Drifters."
