First Samurai

A young warrior known as the First Samurai watches helplessly as a malevolent demon lord overwhelms both him and his mentor through dark sorcery, resulting in his master's tragic death. In his final moments, the master calls upon a powerful wizard, whose intervention frightens the demon king enough to flee through time itself. Consumed by grief and a thirst for vengeance, the samurai apprentices himself to the wizard and masters the arcane arts, eventually wielding an enchanted blade. He then pursues his fallen master's killer across the temporal divide into an uncertain future, determined to settle their blood debt.
