Possessed by: Yasuda Nagahide.

The current incarnation of Yasuda Nagahide who shows up in Takaya's class one day after hypnotizing everyone into believing that he's been one of Takaya's best friends for ages. He is described as being a prodigy at Jouhoku High who is popular both with the teachers and the girls. He wears glasses, has a well-proportioned body, and gives the impression of cool maturity. He is around two years older than Takaya and lives alone. He appears to have cut off all ties with his family.

Notes: He appears as 'Chiaki' in narration. Naoe and Haruie call him 'Nagahide', and Takaya calls him Chiaki. Most of the students at Jouhoku High call him Chiaki-kun.

Titles: Izumi no Kami

Historically: the son of Kakizaki Kageie. He was sent to Odawara Castle in Sagami when the Kenshin and the Houjou clans struck a peace treaty in an exchange of hostages with Houjou Saburou (Uesugi Kagetora). The fate of Kakizaki Haruie was unknown when his father was accused of treason. There are theories that he either died in 1575 along with his father, or that he was murdered by Uesugi Kagekatsu's faction in 1578 during the Otate no Ran.

In Mirage of Blaze: He was one of Uesugi Kagetora's most loyal followers as well as the leader of his faction in the Otate no Ran, and was killed by Uesugi Kagekatsu's followers. He is now one of the Yasha-shuu under Kagetora's command. Haruie possesses female bodies (the only member of the Yasha-shuu to do so) in search of a lover who died two hundred years ago.

Of the Yasha-shuu, he is the one who excels most at the spiritual sensing ability called reisa.

Possessed by: Takeda Shingen (temporarily)

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'.

The headman of Nakagaya village in Matsumoto who submitted a petition to lower taxes in Matsumoto to the same level as that of surrounding areas, thus inciting the Kasuke Uprising. He was one of the 28 ringleaders executed, along with his two sons and younger brother.

It was said that as he was being crucified, Kasuke set a curse against Matsumoto Castle, whose main tower began to tilt from that time and remained tilted until its major renovation in the 1950s.

He was enshrined in 1736, fifty years after the uprising, in a small shrine within the Kasuke home. Two hundred years after his death, the Joukyou Gimin Shrine was built in his hometown (now Sankyou Nakagaya in Azumino), and his and the remains of twelve other people executed with him were transferred there. In 1992 the Joukyou Gimin Memorial was founded.

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.

One of Takaya's classmates who thinks Takaya is joking about not remembering Chiaki and gives him a lecture on friendship. He is a member of the Soccer Club.

He sits directly in front of Takaya in class. His family owns a tofu shop with a history going back to the Edo Period.
