Shin Onimusha: Night of Genesis

Shin Onimusha: Night of Genesis is a manga adaptation released in 2006 to coincide with the launch of the PlayStation 2 action game Shin Onimusha: Dawn of Dreams. It was serialized in Kadokawa Shoten's Shonen Ace magazine, serving as a companion piece intended to expand upon the lore and character dynamics of the game's dark, Sengoku-period fantasy setting. The adaptation focuses on bridging narrative gaps while introducing readers to the new protagonists and the demonic Genma threat.

The manga was illustrated by Oosaki Mitsuru, who was tasked with translating the high-octane, stylized combat of the Capcom game into a static, sequential medium. Oosaki utilized a sharp, energetic linework style that prioritized the fluid movement and gothic aesthetic established by the game's art direction. Upon its release, the volume was received primarily as a collectible for fans of the Onimusha series looking for supplementary character development and visual explorations of the game's dramatic atmosphere.
