Tenchu - Shadow Assassins [USA]

Tenchu: Shadow Assassins (known in Japan as Tenchu 4) is a stealth game developed by Acquire for the Wii and From Software for the PSP and published by From Software in Japan and Ubisoft in North America and Europe for Wii and the PlayStation Portable in 2008.

In the land of Lord Gohda, peace has not been fully restored and rumors of betrayal have been swirling around the lord and his subjects. As a result, Lord Gohda calls upon the Azuma Ninja, Rikimaru and Ayame, to investigate. Rikimaru soon discovers that someone is planning to start a war. Meanwhile, Counselor Sekiya, Gohda's right hand man, arranges for a fortune-teller to predict the future of Gohda's kingdom. Unfortunately, the fortune-teller turns out to be an imposter and kidnaps Princess Kiku, Lord Gohda's daughter.

Ayame chases after her without hesitation, while Rikimaru goes on another mission for Lord Gohda instead: resume the investigation on the nuisances that have been troubling the land. He then discovers that Daimyo Tado is the one behind all this. Gohda then decides to declare war on Tado and travels to his land with Rikimaru. After Rikimaru succeeds in taking Daimyo Tado's life, the woman who posed as the fortune-teller, a Kunoichi named Rinshi, appears and tries to kill Rikimaru, but fails thanks to the intervention of Tachibana Hyakubei, who was hired by Gohda. After Lord Gohda's order, Rikimaru heads back to the castle. When he arrives however, he is attacked by the guards, who were ordered to consider him a traitor by Sekiya. Ayame had actually succeeded in rescuing the princess but had been attacked by someone who seemed to be Rikimaru, who was actually Rinshi in disguise. Ayame and Kiku then flee the castle as the real Rikimaru arrives, and the two women head for a secret hideout suggested by Sekiya. The Princess then reveals to be Rinshi in disguise and wounds Ayame, but Rikimaru arrives just in time to save her and kills Rinshi.

Gohda, noticing his castle in flames, realizes that it was all Sekiya's doing and orders Rikimaru to get back there and eliminate him. After he seemingly takes Sekiya's life and saves Kiku, Sekiya rises again and reveals himself to be Onikage, who then challenges Rikimaru to a duel. Rikimaru ultimately gains the upper hand but Onikage uses the princess as a shield, forcing Rikimaru to drive his sword through her to get to Onikage and kill him. Ayame, who had followed Rikimaru, cries upon Kiku's death. The extended ending (attained by collecting all of the map pieces in normal mode) shows Ayame speaking in Onikage's voice, suggesting his hatred survived in her since Rikimaru murdered her best friend.
