Gameplay
Although the protagonist changes in every Onimusha title, he is always a skilled swordsman who embarks on a set mission which involves slaying demons and fearsome enemies during the waning years of the Sengoku period of feudal Japan. In each game, the protagonist has the ability to absorb Genma souls from defeated enemies, which help to restore health, infuse power in weapons and armor, and provide power for the elemental attacks of special weapons.
The player controls their character using the D-pad (although later games such as Onimusha 3: Demon Siege and Onimusha: Dawn of Dreams introduced analog stick control) and travels in a fairly linear method, able to rotate slowly with the input of an opposing direction. Characters tend to move slowly and can only slightly increase their speed with the dash maneuver by tapping twice in any direction. Actions common to many action-oriented games, such as jumping, grabbing, and climbing over obstacles, cannot be performed in Onimusha games.
Onimusha is action-oriented with an emphasis on combat, and employing some horror elements. The player has an arsenal of weaponry, ranging from katana to elemental-based broadswords. The player possesses a limited supply of spiritual energy which can be used for magical attacks. These magical attacks, which vary depending upon which weapon is equipped and other offensive attributes, can be improved throughout the game by accumulation of souls from defeated enemies.
Plot Based primarily throughout the Japanese Sengoku period, Onimusha: Warlords starts with the feudal lord Nobunaga Oda being killed during a battle. One of the prominent fighters, Hidemitsu Samanosuke Akechi, receives a letter from his cousin Princess Yuki who is concerned about servants from her castle disappearing. Samanosuke joins with the kunoichi Kaede to rescue Yuki and discover demonic creatures known as Genma. In order to defeat the Genma, the Oni clan grant Samanosuke powers from their kind. Across his fights Samanosuke discovers the Genma have resurrected Nobunaga into serving their needs while intending to sacrifice Yuki and an orphan named Yumemaru to grant him more powers. Samanosuke manages to save Yuki and Yumemaru and kills the Genma Lord, the God of Light Fortinbras. Samanosuke's group then takes different paths.
The sequel, Onimusha 2: Samurai's Destiny, has Nobunaga using the Genma in his forces to unify Japan, wiping out Yagyu village whose clan are Genma exterminators. The clan's only survivor, Jubei Yagyu, goes on a quest to avenge his clan while learning he inherited Oni powers from his mother as he uses them alongside the Oni's five orbs to battle Nobunaga's soldiers. Across his journey, Jubei meets several allies who also seek Nobunaga's life. Jubei manages to infiltrate Gifu castle and confronts Nobunaga alone. Although Jubei kills Nobunaga, the warlord's soul escapes and later reconstitutes himself. The spin-off Onimusha: Blade Warriors has the cast from Warlords and Samurai's Destiny in a new battle against Nobunaga's forces.
The third game, Onimusha 3: Demon Siege, has Samanosuke's clan attacking the Oda forces again. Before confronting Nobunaga, Samanosuke is transported to Modern Paris as a result of an experiment made by the Genma scientist Guildernstern to enable his kin to conquer more lands. In the meantime, service agent Jacques Blanc is a victim of Guildernstern while transported to Japan's Sengoku period. There, Jacques is granted Oni powers by an Oni who tells him to join forces with this timeline's Samanosuke and defeat Nobunaga if he wishes to return home. While Jacques aids Samanosuke in the past, in the future Samanosuke is helped by Jacques' family to investigate the Genma. In the end, the two Oni warriors are successful in stopping the invasion and returning to their respective times. Samanosuke manages to slay Nobunaga and seal his soul within the Oni Gauntlet to avoid another resurrection.
The fourth game, Onimusha: Dawn of Dreams, had Nobunaga's servant Hideyoshi Toyotomi unified Japan with the Genma whom he supported in their actions. His illegitimate son, Hideyasu "Soki" Yuki, goes on a quest to defeat Hideyoshi and stop the Genma. He is aided by several other warriors, including an elder Samanosuke who recognizes him as the Black Oni, the God of Darkness. After mastering his Oni powers, Soki joins with his friends to defeat Hideyoshi's army. In the aftermath, it is revealed that Hideyoshi was a mere puppet of the Genma Triumvirate who wish to resurrect Fortinbras at his full power as the Genmas' God of Light. Although the Genma Triumvirate and Hideyoshi are defeated, Fortinbras resurrects with Soki using the Oni Gauntlet to destroy the Genma and restore the country's peace at the cost of his life. Soon after, Samanosuke embarks on a quest to seal away the Oni Gauntlet to prevent Nobunaga from being released.
The fifth game, Onimusha: Way of the Sword follows a new storyline, featuring Miyamoto Musashi, a ronin who is killed by Genma with his longtime rival, Sasaki Ganryu. Both are revived and given Oni Gauntlets by Minamoto no Yoshitsune, a deceased Onimusha turned evil. During his quest to fully revive as a human and stop Yoshitsune's plans, Musashi is aided by the spirit of Shizuka Gozen, an Oni and Yoshitsune's former wife who resides on his gauntlet, a 700 year old Onimusha called Ono no Takamura and his apprentice Izumo no Okuni, as well as the occasional help of the spirit of Murasaki Shikibu. With help from the mysterious Dokyo, Yoshitsune returns to the world of living by absorbing the human souls Ganryu collected in order to become stronger, but is destroyed by Musashi. Afterwards, Shizuka returns to the afterlife, while Musashi manages to fully ressurrect and embarks on a journey to track down Dokyo and Ganryu, who are still at large.
