DRAG-ON DRAGOON: Shi ni Itaru Aka

In the war-torn realm of Midgard, a mysterious and devastating affliction known as the Red Eye disease ravages the land. Those infected by this terrible plague become targets of an unrelenting purge led by a lone warrior named One. Driven by a dark and uncompromising mission, he travels across the blighted landscape, executing anyone who bears the mark of the sickness to prevent its further spread. He does not undertake this grim crusade alone. At his side stands Nero, an elven companion whose presence bolsters his perilous journey through a world teetering on the edge of ruin. Together, they carve a bloody path through Midgard, bound by a shared purpose that extends far beyond merely containing the disease. Their violent campaign is ultimately in service of a much larger, more dangerous objective. One and Nero are searching for the elusive leader of the Cult of the Watchers, a shadowy figure deeply entwined with the region's escalating catastrophe. Uncovering this leader’s identity is the key to unraveling a greater mystery: the true origin of the Black Dragon. As they hunt down the afflicted and pursue the cult's mastermind, their quest becomes a desperate race to unearth the source of the darkness threatening to consume their world entirely.
