In Nobunaga's Ambiton series, he is often known as Sekiguchi Ujihiro (関口氏広).

Historical Information
Chikanaga was a second son of Sena Ujisada. In 1525, when Sekiguchi clan became leaderless, Chikanaga was appointed as a new head of the clan. He came into the service of Imagawa somewhere around 1531.

Chikanaga's daughter was sent into Imagawa Yoshimoto's care and, in 1557, was married to Matsudaira Motoyasu, thus making Chikanaga become father-in-law of Motoyasu.

After Yoshimoto's death at Okehazama, Chikanaga served Imagawa Ujizane, but since Motoyasu left Imagawa, Ujizane suspected him of treason and ordered him to commit suicide.
