Also known as: Nagao Kagetaka (長尾景孝), Nagao Toukurou (長尾藤九郎)
Title: Yamato no Kami (大和守)

Historically: Son of Nagao Akikage, he became head of the Sousha-Nagao Clan at a young age. He later (around 1545) passed the position to his younger brother Nagao Kagefusa. When the clan was destroyed by Takeda Shingen and their territory lost, the family escaped into Echigo. There Kagefusa became a monk, and Kagetaka was adopted by Naoe Sanetsuna when he married Sanetsuna's daughter, Osen-no-Kata. He succeeded his adopted father as master of Yoita Castle in 1577 and was a vassal of Uesugi Kenshin. He promptly took the side of Uesugi Kagekatsu during the war for succession after Kenshin's death and mobilized the members of the Naoe Clan at the castle to subdue Kagetora's troops.

After the intra-house war and Kagekatsu's victory, a question of reward was called into question. Yasuda Akimoto, one of Kagekatsu's trusted commanders, had promised rewards to Shibata Shigeie, Mouri Hidehiro, and others to convince them to join Kagekatsu's side. However, Yamazaki Hidenori, Naoe, and others objected, for they had risked life and limb at Kasugayama Castle from the very beginning of the battle, while Shibata Shigeie and the others had been lured by promise of reward from Yasuda Akimoto.

Yasuda Akimoto committed suicide when he could not keep his promise of reward. Later, Mouri Hidehiro, carrying a grudge for his death, murdered Yamazaki Hidenori at Kasugayama Castle; Naoe, who was with him at the time and took up a sword to defend himself, was killed as well. His death ended the Naoe line, which Kagekatsu later resurrected by marrying Naoe's widow, Osen-no-Kata to Higuchi Kanetsugu and commanding him to take the Naoe name.

In Mirage of Blaze: According to Kousaka Danjou, and Houjou Ujiteru he was the ringleader of Uesugi Kagekatsu's forces in the Otate no Ran. He is now Uesugi Kagetora's protector and one of the Yasha-shuu under his command. He alone, as Kagetora's protector, was given the power to perform kanshou on other souls, a power he used to force Kagetora's soul into Minako's body.

Also called: Oda Kippoushi
Title: Kazusa no Suke, Owari no Kami

Historically: The first of the "Three Unifiers"; born in Owari to a samurai, his unbridled, ruthless ambitious and military tactical genius enabled him to gain control of the imperial court in 1573 after having driven the shogun out of Kyoto. His seal read "the realm subjected to military power". Murdered at the age of forty-nine by his vassal Akechi Mitsuhide in the Honnou-ji in Kyoto.

Historically: Second daughter of Sanjou Kinyori, Minister of the Left and second legal wife of Takeda Shingen, a woman of courtly blood who was mother of his original heir, Takeda Yoshinobu as well as two other sons and two daughters (the older of whom married Houjou Ujimasa). Her name is literally written as "person of Sanjou (Clan)".

She was described as a great beauty and fervent in her devotion to Buddhism. Since Shingen eventually named the grandson of a concubine heir to the clan, it is thought that Sanjou and Shingen did not get along.

In Mirage of Blaze: She and Kousaka Masanobu break the barrier over Takeda Shingen's tomb, the Maenduka, and attempt to resurrect Shingen by using Narita Yuzuru as a vessel for his spirit. She herself takes over the body of Takeda Yuiko but is exorcised by Takaya and Naoe with kouhou-choubuku.

Possessed by: Sanjou (temporarily), Princess Itsu (temporarily).

Takeda Yuiko is a descendant of the Takeda Clan. She is able to sense spirits, an ability which makes her a target for the onryou. She is around the same age as Takaya; Takaya first gets a hint of his powers when he sees her engulfed in heatless flame as Sanjou, who had possessed her body, fought with her for control.

After the Sanjou episode, Yuiko and Saori become penpals. Saori later visits her in Tokyo.

Also known as: possibly Houjou Ujihide (北条氏秀), Houjou Saburou (北条三郎), Saburou Kagetora (三郎景虎)

Historically: Uesugi Kagetora was the seventh son (sixth to survive to adulthood) of Houjou Ujiyasu, younger brother of Houjou Ujimasa, Houjou Ujiteru, Houjou Ujikuni, Houjou Ujinori, Houjou Ujitada, and older brother of Houjou Ujimitsu. His mother was the sister-in-law of Tooyama Yasumitsu, a vassal of the Houjou Clan (other sources say Zuikeiin, Ujiyasu's principle wife). It's likely that he and Houjou Ujihide were two different people and that Ujihide was the son of Houjou Tsunashige and living in Edo while Saburou was living in Echigo, so most historians refer to him as Houjou Saburou when describing his early life.

As a child, he was sent into the priesthood at Souun Temple in Hakone, then sent as hostage to Takeda Shingen of the Takeda Clan in the three-way alliance between Houjou, Takeda, and Imagawa formed in 1554 (though this last point is now in dispute, as it is told only in the Records of Ancient Battles of the Eight Kanto Provinces and recorded in none of the Takeda Clan records.)

He was adopted by his uncle Houjou Genan in 1569 and married Genan's daughter.

When the Houjou and Uesugi clans formed an alliance in 1569, Saburou was sent to Uesugi Kenshin in an exchange of hostages with Kakizaki Haruie. (At first, the hostage was set to be Houjou Ujimasa's third son Kunimasumaru, but Ujimasa could not bring himself to send off his son, who was then still a baby.) Saburou was sent to the Uesugi clan in early 1570. Kenshin, who never married, developed a liking for the handsome and intelligent Saburou. He married his niece Seienin, the daughter of Nagao Masakage and older sister of Nagao Akikage (Uesugi Kagekatsu) to Saburou, gave him the name Kagetora (a name that had once belonged to Kenshin himself), and adopted him into the Uesugi Clan.

When Kenshin died suddenly in 1578 without naming an heir, Kagetora and Kagekatsu, similarly adopted by Kenshin, fought for succession to the position of clan head (the Otate no Ran). Though Kagetora held the early advantage with the backing of Uesugi vassals such as Uesugi Kagenobu, Honjou Hidetsuna, Kitajou Takahiro, and the Houjou Clan, the tide of the battle turned with Takeda Katsuyori's betrayal to Kagekatsu's side.

When the Otate fell in 1579, Kagetora attempted to escape to Odawara Castle, but was betrayed at Samegao Castle by Horie Munechika and committed suicide. His wife committed suicide along with him (though there are also accounts that she remained behind at the Otate and committed suicide there when her brother Kagekatsu refused Kagetora's surrender.) His oldest son Doumanmaru died at the hands of Kagekatsu's troops along with Uesugi Norimasa, and the rest of his children were believed to have died along with their parents.

In Mirage of Blaze: He was born to Houjou Ujiyasu and Zuikeiin as their eighth (seventh to survive to adulthood) and youngest son. After his death in the Otate no Ran, he was charged by Uesugi Kenshin to become kanshousha in order to ensure that the peace of Japan is not disrupted by the onshou as the leader of the Yasha-shuu and the commander of the Meikai Uesugi Army.
