Oboro is the younger sister of Onimaru and one of the protagonists in Onimusha: Tactics.


Oboro is a kunoichi from Iga village. Her parents died when she and her brother were still infants. Oboro's dying mother brought both her and her brother along with an Oni Gauntlet to Iga village where she was soon found by legendary Iga ninja, Sandayu Momochi. With her dying breath, she then told him that she is a descendant of the Oni Clan; due to her mother's heritage, Oboro possesses the blood of the Oni. Oboro and Onimaru were then raised by Sandayu and trained to become warriors.
