Sena (Samurai Warriors)

Sena (瀨名) is the niece of Yoshimoto Imagawa, one of the three feared daimyo of the Tokaido region. She later became the first wife of Ieyasu and mothered both Nobuyasu Matsudaira and Kamehime. She was best known for possibly initiating a conspiracy against Nobunaga for her husband's benefit. There is speculation that she planned to get revenge on Oda because her adoptive father, Yoshimoto, was killed by them. So she sent a letter to Takeda, hoping that Takeda would accept her and her son as his allies and exterminate the Oda clan. Takeda received a letter from her and also certified that she would marry one of Takeda's elite generals. Later the Takeda clan would become one of the clans that founded the Anti-Oda coalition.
