"Onimusha: Twilight of Desire" is a manga series that blends historical fiction with supernatural elements, set in feudal Japan during the tumultuous Sengoku period. The narrative centers on the struggle between humanity and demonic forces, intertwining political intrigue, warfare, and mystical themes. The protagonist, a skilled warrior named Jubei Yagyu, is tasked with protecting the land from the encroaching darkness of the Genma, a race of malevolent demons seeking to overthrow humanity. Jubei wields the Oni Gauntlet, a powerful artifact that grants him enhanced abilities and the capacity to combat the Genma.

The story begins with Jubei being drawn into a conflict involving the Oda clan, led by the ambitious warlord Nobunaga Oda, who has formed an unholy alliance with the Genma to further his conquest of Japan. Jubei’s journey is marked by encounters with various allies and adversaries, including other warriors, mystical beings, and political figures, each with their own motivations and ties to the unfolding chaos. As the Genma’s influence spreads, Jubei must navigate treacherous alliances, uncover ancient secrets, and confront his own inner demons to fulfill his destiny as a protector of humanity.
