Onimusha is a Capcom action-adventure series set in feudal Japan, blending historical figures with supernatural elements as players control Oni-powered warriors battling the demonic Genma. As of December 2025, the franchise has sold 9 million copies worldwide, making it Capcom's tenth best-selling series. The series began in 1997 with Yoshiki Okamoto's concept for a "Sengoku Biohazard" (a ninja-themed Resident Evil), and it famously used real actors as character models, including Takeshi Kaneshiro and Jean Reno. Though originally planned as a trilogy, a fourth mainline game (Dawn of Dreams) arrived in 2006, alongside spin-offs like mobile, browser, and a 2025 VR arcade title. Recent remasters of the first two games were released in 2018/2019 and 2025, while the next mainline entry, Onimusha: Way of the Sword, is set for September 4, 2026. Gameplay emphasizes third-person hack-and-slash combat and puzzles, where absorbing Genma souls powers up weapons, though movement is deliberately slow and lacks jumping or climbing.
