ZAN

During Japan’s Warring States period, the warrior ZAN was locked in a fierce battle at Azuchi Castle. Guided by the mysterious voice of a young girl, he steps beyond time and space into another world—a realm where he must face powerful rivals and monstrous beings known as Tropes. RIKKA, the ruler who commands the Tropes—the very symbols of life—maintains the world’s order. Questioning the justice behind his own battles, ZAN embarks on a journey to uncover the truth, joined by Panther, a mechanical lifeform, and Uzume, the enigmatic girl who called out to him.
