今川 彦五郎 鞠 氏真

Mari is the daughter of Imagawa Yoshimoto, who was defeated by Kuon at the Battle of Dengaku Hazama. While her manner is childish and innocent, she was raised as a leader first and foremost. As the child of a daimyo, she was raised to see death in battle as a matter of course and an inevitability of fate. As such, she does not resent the loss of her mother, though she does grieve.

Like Kazuha, she as a student of Tsukahara Bokuden and is a master of the sword.
