Onimusha: Warlords - Plot

Plot

The story begins in 1560 with a cinematic sequence set during a Battle of Okehazama between the forces of Imagawa Yoshimoto and Nobunaga of the Oda clan, with Samanosuke participating in fighting on Yoshimoto's side. As Oda clan's victory seems imminent, Nobunaga laughs until a stray arrow pierces his throat. A year later Samanosuke receives a letter from his cousin Princess Yuki of the Saitō clan. In the letter, Yuki says that maids and servants have been disappearing and she suspects monsters to be the culprit and also request that Samanosuke saves her from the castle before she ends up as one of the victims. Samanosuke and Kaede arrive at the castle but they're too late to rescue Yuki. The last scene shows an army of Oda soldiers marching on with a pale but living Nobunaga leading them on a horse.

The game begins as Samanosuke and Kaede split up and head to the keep. Samanosuke soon finds some Genma creatures with an unconscious Princess Yuki. However, as the heroes have a brief reunion, a gigantic genma Osric emerges from the ground. Samanosuke attempts to defend Yuki, but is sent flying against the wall. As he lies unconscious, he is visited by the twelve oni, who give Samanosuke the power to destroy the genma and absorb their souls with a mystical gauntlet.

Samanosuke wakes up and enters a cave, where he finds the Raizan. In a dry moat, he finds and kills Osric. Samanosuke then finds a laboratory and a genma scientist Guildenstern operating on a human. Guildenstern reveals that he has resurrected Nobunaga who then made a pact swearing his allegiance to the demons. Guildenstern escapes and sends a creature called Reynaldo, but Samanosuke defeats it and obtains the Enryuu in the laboratory. He then proceeds to a keep where he goes inside to find the entire place a derelict and encounters a man named Tokichiro Kinoshita wrestling with a young boy. After the boy escapes, Tokichiro states that he is a servant of the Oda clan and wonders if Samanosuke would be interested in joining, but Samanosuke refuses, saying that he controls his own life. As he moves on, Samanosuke sees Kaede chasing the boy and learns the boy's name is Yumemaru (Kaede later learns that he is an orphan and Yuki has raised him like a brother). As Samanosuke nears the top of the keep, he sees Yumemaru in the hands of enemy, however before he can give chase, Tokichiro confronts him once again with an offer to join the Oda clan. He also reveals that the dark ceremony involving a human sacrifice will take place soon and Princess Yuki's skull would be filled with her blood; Fortinbras, the king of demons, will bless it and Nobunaga will drink it in order to become powerful and destroy the Saitō clan. Samanosuke defeats a strong genma Marcellus on the roof and receives the Shippuu. With this, he is able to rescue Yumemaru and brings him to a secure room in the keep. Samanosuke then tells Kaede to stay with Yumemaru and the woman while he looks for Yuki in underground. While he searches, he finds himself once again in the presence of Tokichiro; with one last request to join the Oda clan, Tokichiro activates a trap device and Samanosuke is pulled down into the earth. Meanwhile, Kaede is rendered unconscious by a genma which looks like Samanosuke and Yumemaru is kidnapped by a woman. When she awakens, Kaede is led to the prison and finds Yuki locked in a cell. However Guildenstern arrives from the darkness of the cell and leaves Kaede to die at the hand of a powerful genma; she escapes once it is dead.

Samanosuke awakens and kills his counterpart in the underground passage. He makes his way back into the keep and arrives in the room where the woman and Yumemaru are. The woman reveals her true form, which is that of an insect-like genma Hecuba, and erects a door to the demon world which she flies into with Yumemaru. When Samanosuke faces her, she reveals that Yumemaru is to be killed in front of Yuki which will heighten her sorrow, thus granting Nobunaga even more power during the sacrifice. Samanosuke and Kaede eventually vanquish the insect genma. As Samanosuke makes his way through the demon door, he encounters Guildenstern who summons a more powerful version of Marcellus. After defeating him, Samanosuke makes his way into Fortinbras' throne room, where he finds Yuki and Yumemaru trapped on the upper level. Before he can free them, Fortinbras enters the room: after a brief conversation, the two clash. It would seem that Samanosuke killed Fortinbras and he frees Yumemaru and Yuki as Kaede enters the room. As they exit, the place comes crashing down and Fortinbras finds the strength to grab Samanosuke. Kaede, Yumemaru, and Yuki escapes as the strain of Fortinbras's grip causes Samanosuke to spit up blood. Some of the blood falls on the gauntlet and Samanosuke becomes an onimusha (oni warrior) and finishes-off Fortinbras by stabbing him in his central eye. As Samanosuke transforms back into a human, he sees Nobunaga's reflection in Fortinbras' eye and the two stare at each other as the room continues to collapse.

During the ending sequence Yuki and Yumemaru follow Samanosuke’s advice and travel the world. After the end credits, Samanosuke is seen alive, viewing Inabayama Castle from afar, and still possessing the gauntlet.
