The game's scope of the
Sengoku period is limited in contrast to previous games.
Samurai Warriors 5 focuses on events leading up to the
Honnō-ji Incident, with
Nobunaga Oda and
Mitsuhide Akechi being the prominent figures of the story. The story is divided between Nobunaga and Mitsuhide's POVs (referred to as ''Nobunaga's side
and Mitsuhide's side''). While Nobunaga's story focuses on his rise as an ambitious and charismatic underdog, and eventual death as the "Demon King" in Honnoji, Mitsuhide's story focuses on his personal friendships, relationship with Nobunaga and eventual falling out after Nobunaga refuses to send support to the Amago Clan, leading to their destruction by the Mori Clan. The game introduces Mitsuki, a fictional kunoichi who is the orphaned daughter of Nobunaga's younger brother Nobuyuki Oda, who believes that Nobunaga is her real father and tries to win his approval by joining his cause while refusing to believe Nobunaga's continuous claims that he's not her father. A major subplot is the mystery regarding the person inciting major rebellions against Nobunaga and
Ieyasu Tokugawa following the fall of the Ashikaga Shogunate, which is eventually revealed to be the Iga ninja and
Hanzo Hattori's friend Momochi Sandayu (a fictional character based on folklore) whose real motivation was the destruction of the Samurai-class. Momochi is later defeated by Ieyasu and Hanzo following Nobunaga's death but it's implied that he managed to cheat death. Mitsuhide is later defeated by
Hideyoshi Toyotomi at Yamazaki, with him dying from his wounds in Mitsuki's arms. The game ends with both Hideyoshi and Ieyasu Tokugawa stating their desire to continue where Nobunaga left off and unite all of Japan, setting off their eventual rivalry. ==Characters==
