Onimusha: Warlords is the first game of the Onimusha series. It went through many changes and was released as Genma Onimusha for the Xbox. The game was also ported to PC Windows as Onimusha: Warlords, although this version was only released in Asia. Also Onimusha: Warlords was originally going to be for the PlayStation, but since the release of the PlayStation 2 (Onimusha: Warlords was about 50% done at that time) it was moved to the PlayStation 2.
The game features samurai Samanosuke Akechi, modeled after actor Takeshi Kaneshiro, determined to save Princess Yuki of the Saito clan and defeat Nobunaga, resurrected after signing a pact with demons. The game also features Kaede, an expert female ninja who provides Samanosuke with information. Kaede was originally sent to assassinate Samanosuke by the Iga ninja clan for reasons unknown, but she did not kill Samanosuke for reasons that were also unknown, but she develops trust and deep feelings of love (as shown in Onimusha Blade Warriors) for the samurai and agrees to join him as his confidant. Samansosuke travels throughout all of Inabayama Castle where he searches for clues of Princess Yuki's whereabouts, finds special weapons, and solves various puzzles.
