Also known as: birth—Bontenmaru (梵天丸), adult—Tojirou (藤次郎), posthumous—Teizan (貞山), self-introduction—Fujiwara no Masamune (藤原政宗), religious—Takeru Hikonomikoto (武振彦命), nickname—One-Eyed Dragon (独眼竜)

Date Masamune was a powerful daimyo in the Northeastern part of Japan during the Sengoku Period. He was the 17th-generation head of the Date Clan and the founding daimyo of Sendai-han. He was the eldest son of Date Terumune and Yoshihime, the daughter of Mogami Yoshimori.

Masamune was born in Yonezawa Castle (modern-day Yamagata Prefecture). He lost the use of his right eye after falling ill of smallpox in his childhood, and would later come to be known as the One-eyed Dragon. However, because of it his mother thought him unfit for rule of the clan, and favored his younger brother. When Date Terumune retired from the position of the clan head in 1584, Masamune killed his brother and became the head of the clan at 18.

Masamune was known as a brilliant tactician. Shortly after he became head of the clan, Oouchi Sadatsuna, a Date vassal, defected to the Ashina Clan in the Aizu region of Mutsu Province. Masamune declared war on the Ashina for the betrayal, but was forced to retreat by the Ashina general, Iwashiro Morikuni. Three months later, Masamune laid seige to Oouchi's stronghold at Otemori. It was said that he put some 800 people to the sword in retaliation for the betrayal. Thereafter the Hatakeyama Clan, the traditional rival of the Date Clan, kidnapped Masamune's father, who was then killed in battle when Masamune and his troops engaged the kidnappers. War ensued between the two clans, and Masamune would ruthlessly subjugate his neighboring clans, even those who were allied by marriage or kinship. He defeated the Ashina Clan in 1589, but was called by Toyotomi Hideyoshi to lay siege to Odawara Castle of the Houjou Clan.

He served both Toyotomi Hideyoshi and Tokugawa Ieyasu, though neither trusted him completely due to his ambition and aggression. Under Tokugawa Ieyasu Masamune controlled one of the largest fiefdoms in Japan and turned Sendai from a small fishing village to a large and prosperous city. He encouraged foreigners and was largely lenient towards Christanity and its practioners. He funded and backed the first Japanese expedition to sail around the world, which visited such places as the Philippines, Mexico, Spain and Pope Paul V in Rome.

He died in Edo at the age of 70 of esophageal cancer, and was entombed in the Zuihouden according to his last will and testament. His second son (eldest son by his legal wife Megohime) Date Tadamune inherited the position of clan head after him.

Notes: She appears as 'Ayako' in narration. Naoe and Nagahide call her 'Haruie', and Takaya calls her 'Nee-san'.

Also known as: Katakura Kojuurou Kagetsuna (片倉小十郎景綱)

A military commander of the Sengoku era and hereditary vassal of the Date Clan. The Katakura family traditionally took the nickname of 'Kojuurou', so Katakura Kagetsuna is better known as Katakura Kojuurou.

Kojuurou first served Date Masamune's father, Date Terumune, as a junior page, then became Date Masamune's attendant in 1575. He was later appointed a strategist, and participated in most of Masamune's important wars where he rescued the Date Clan from many tight spots. His wisdom was extolled by Toyotomi Hideyoshi, and his name was a byword for loyalty. (He was called 'Katakura Kagetsuna the Wise', and he, along with 'Date Shigezane the Brave', were named 'the twin jewels of the Date'.)

Kojuurou died in 1615 of illness.

The head abbot of Jikou Temple belonging to the Shingon school whom Naoe asks to help train Takaya in his powers. He is an old acquaintance of Naoe (Tachibana Yoshiaki)'s family and knows something of Naoe true powers.

Kokuryou is about 70 years of age and of short stature, but remarkably active. Ayako describes him as a stubborn person who is scary when mad, so is on her best behavior around him.

Also known as: Yoshihime, Youtokuin (陽徳院)

Only daughter of Tamura Kiyoaki who married Date Masamune in 1579 at the age of 12. An assassination attempt against Masamune caused him to suspect the Tamura clan, and he ordered the executions of Megohime's nurse and several of her attendants. Their marital relations became strained by these events, but were eventually mended, and Megohime gave Masamune four children, including his heir Date Tadamune.

She lived at the Date mansion in the court of Toyotomi Hideyoshi and acted as her husband's diplomat to the court. In 1636, at the death of Masamune, Megohime became a nun and took the Buddhist name of Youtokuin.

Mogami Yoshiyasu was the eldest son and heir of Mogami Yoshiaki, but the two were not on good terms. In 1611, while en route from house arrest to Mount Kouya, he was attacked and badly wounded. He killed himself, crying "Damn you, cruel Father!"

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.

Blood type: O
Possessed by: Uesugi Kagetora

At the beginning of the story Takaya is a seventeen-year-old high school delinquent with no memory of his past. His parents divorced when he was a first-year junior high school student, probably because his father started drinking when his business failed. His mother remarried and lives in Sendai.

He was born and raised in Matsumoto and lives there with his sister, Miya. He attends Jouhoku High and is in the same class (Year Two Group Three) as his best friend, Narita Yuzuru.

Notes: He appears as 'Takaya' in narration. Nagahide and Haruie call him 'Kagetora', and Naoe calls him 'Kagetora-sama' and 'Takaya-san'. Most of the students at Jouhoku High call him 'Ougi-kun' (Chiaki calls him 'Ougi' at school). Miya calls him 'Onii-chan', and Yuzuru calls him 'Takaya'.

Also called: Takeda Katsuchiyo, Takeda Harunobu
Title: Shinano no Kami

Historically: Daimyo of Kai who became the head of the Takeda clan by rebelling against his father. Conquered Shinano and fought against Uesugi Kenshin. The two clans clashed five times on the plains of Kawanakajima, where neither gained complete victory until Shingen died of illness in his campaign against Oda Nobunaga and Tokugawa Ieyasu.

Possessed by: Mogami Yoshiaki

Second-in-command of a powerful political faction (the Hirabayashi Group) within the ruling party of the House of Representatives of the Japanese National Diet. Ueshima was involved in a graft case and made a deal with Mogami Yoshiaki to kill the bribe suspects and keep the truth from coming to light. In return, he agreed to allow Mogami Yoshiaki to use his body as spirit vessel.

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.
