Okatsu

Okatsu (お勝) is an original character in the Kessen series. She is named after Ieyasu's noble concubine, Eishoin. She apparently disguised herself as a man and fought at Sekigahara and Osaka as "Okatsu no Kata" (お勝の方).

In both games, she wields a sword and some shuriken.

Story
In Kessen, Okatsu is a kunoichi who is rumored to be one of Hanzō Hattori's descendants. She loyally attends to Ieyasu and is by his side at all times. Although she never personally takes to the field, she is keen of the war's situation and reports valuable information for her lord. She additionally acts as his personal bodyguard and will defend him when he is faced with immediate danger. If Ieyasu's army falls in battle, Okatsu will kill the soldiers closest to Ieyasu before requesting for him to retreat. Should Ieyasu be forced to commit suicide after his last defeat, she will solemnly pay her respects at his grave.

A younger Okatsu resumes her role in Kessen III. She is introduced when Ieyasu and Nobunaga formerly make an alliance with one another at Azuchi Castle. Although Nobunaga was on guard by her presence on the ceiling, she amuses him by saying that the castle's defenses were easy to infiltrate. From then on, she serves as an aid for Ieyasu and eventually leads her own unit in battle. When Nobunaga is presumed dead after Honnoji, she is the one who suggests for Ieyasu to take over their lord's ambition.

Okatsu no Kata eventually makes her own appearance in Saihai no Yukue as Ieyasu's loyal wife. She wears an armor decorated with hearts and fights with a sword.
