Shinjou-no-tsubone was the daughter of Kumagai Nobunao. Mirage of Blaze gives her name as Lady Tomo, but her real name is unknown. She married Kikkawa Motoharu in 1547 and gave birth to Motoharu's eldest son Kikkawa Motonaga the following year, followed by Mouri Motouji and Kikkawa Hiroie. Although their marriage was a marriage of convenience, it was said Shinjou-no-tsubone and Motoharu grew to love each other deeply, and Motoharu never took a concubine.

In the Intoku Taihei Chronicles by Sen'a, a warrior and poet of the mid-Edo Era, Shinjou-no-tsubone is described as having a 'white, pockmarked head' who 'walked bowlegged with a hunched back.' He called her 'a woman of once-in-a-generation ugliness.'

Tengu are mythical creatures found in Japanese folklore and traditionally depicted with human, monkey and avian features. Though their shapes vary, typical characteristics include red faces, long noses, and wings.

Title: Kantou Kanrei (関東管領)

Historically: Fourth son of the noted warrior Nagao Tamekage, Kenshin wrested control of the Nagao clan from his brother Nagao Harukage and fought for control of Echigo Province. He accepted the name Uesugi Masatora when he gave refuge to his nominal lord, Uesugi Norimasa, and at his urging campaigned to push the Houjou out of the Kantou Region.

He adopted the name "Kenshin" when he became a Buddhist monk and a devotee of Bishamonten. The standard his army carried onto the battlefield bore the character 毘 ("bi") for Eight-Sword Bishamonten. He battled Takeda Shingen five times at Kawanakajima, as well as the Houjou and Ashina clans and Oda Nobunaga, whom he defeated despited being outnumbered. However, Kenshin died soon after the battle. He named his two adopted sons, Uesugi Kagetora and Uesugi Kagekatsu, his heirs, hoping that they would divide the Uesugi lands peacefully between them after his death.

In Mirage of Blaze: He became a god of war after his death, ascending from Nin Dou to Ten Dou, and established the Meikai Uesugi Army to ensure that the peace of Japan is not disrupted by the onshou. He named Kagetora as its commander.
