Onimusha 3: Demon Siege, released in Japan and Europe as Onimusha 3, is an action-adventure game developed and published by Capcom. It is the third game of the Onimusha series and was released for the PlayStation 2
The game opens with Samanosuke Akechi (Takeshi Kaneshiro) destroying the monstrous Genma army in Japan in 1582. It then jumps to modern-day Paris 2004, featuring Jacques Blanc (voiced by Jean Reno) riding on his motorcycle to help his friend Phillipe. The Genma army then begins its invasion of Paris near the Arc de Triomphe.
The game returns to Samanosuke in feudal Japan and fights his way to Honnoji Temple, which is on fire from a raging battle. Samanosuke battles and kills Ranmaru Mori (Joshua Keaton) and approaches Oda Nobunaga. However, before they can fight, a portal opens on the floor and Samanosuke is pulled through it.
Meanwhile, the French military has been fighting several monsters since 1582, but the soldiers can not hold them for long. Jacques arrives on the scene finding Phillipe injured from the battle. Suddenly, Samanosuke appears from a portal in a Paris alley right where Jacques is fighting the Genma monsters.
Jacques Blanc runs out of ammo just as he and Phillipe are ambushed, but Samanosuke manages to rescue them. Samanosuke and Jacques meet but are unable to properly communicate.
The time portal reappears and pulls Jacques and Phillipe through to Japan. Samanosuke makes his way towards the center of the hysteria, the Arc de Triomphe. Samanosuke first meets Michelle, Jacques’ girlfriend, near the Arc and makes his way towards the roof.
There he encounters Guildenstern and finds out he is actually over 400 years in the future in Paris. Samanosuke then fights and destroys Brainstern, a robotic creation.
Jacques Blanc and Phillipe arrive in 16th century Japan where they encounter Samanosuke on his way to Honnoji Temple. Both men realize that to return to their own time period, they must save the current time from destruction.
Samanosuke in 2004 Paris teams up with Michelle and Jacques’s son to save the city from destruction while Jacques and Samanosuke (not player-controlled) struggle to fight Nobunaga in feudal Japan. The two men work together across time to solve puzzles and access new areas. Both men have one goal: destroy the demons plaguing their time.
