In the fifth episode she tells the other warriors about telling A Hundred Stories in order to escape from the forest safely. In episode 10, she confronts Mitsuhide with Sake to kill Nobunaga, and tells her to burn the Honnouji Residence (the place where Nobunaga, Mitsuhide and Hideyoshi were currently lodging at that time) and steals the Crimson Armour from Oda Nobunaga, after distracting the main protagonists. Date Masamune's true identity was not recognised until the tenth episode of the series when Hideyoshi discovered that she had a true resembulance to her school teacher, when Date saved her life, from a fire. Date, takes the Crimson Armour, but is stopped by Tokugawa Ieyasu, who attacks Date and steals the Armour from her, after Tokugawa is defeated and the armour removed from her, Date tries to take the Armour again, but is stopped by Oda Nobunaga, who destroys it, calling it 'unneeded'.
