Intoned by the Yasha-shuu at the beginning of choubuku, 'bai' is the "seed syllable" for Bishamonten, originally known as Vaiśravaṇa.

Historically: The name Fuuma Kotarou was given to each leader of the Fuuma Clan/organization of ninjas which served the Later Houjou Clan, starting with its first leader. The clan started information-gathering and espionage activities in the time of Houjou Souun, the founder of the Later Houjou Clan. The clan name began as 風間, composed of the characters for "wind" and "space", but was changed to its present form, a homophone composed of the characters for "wind" and "evil/demonic/magical."

In its 100 years of service to the Houjou Clan, the most renowned Fuuma Kotarou was the fifth, who served Houjou Ujimasa and his son Houjou Ujinao (unknown - 1603). Stories say that he was 7'1". One of his most famous exploits was in 1580 and the Battle of Kise-gawa, during which he slipped into the enemy camp at night and caused mass chaos. Another famous ninja, Ninokuruwa Isuke, also belonged to the Fuuma Clan.

After the destruction of the Houjou Clan, Kotarou and the Fuuma Clan became thieves near Edo. Kotarou was captured and executed in 1603 from information given by Kousaka Jinai, another ninja-turned-thief who formerly served the Takeda Clan.

In Mirage of Blaze: Fuuma Kotarou leads the Fuuma ninjas in service to the Houjou Clan. He is described as a tall, slender man with broad shoulders and a muscular but supple body. He wears his hair long, tied in a long tail that reaches to his waist.

Also known as: 金八 (Kinpachi), Onhachi, Buddhist Priest Kihachi, Kihachifushi, 走建 (Hashiritakeru, Hasetakeru)

Kihachi is mentioned in the Asahi Daijin (1189) at Takachiho Shrine.

There are many legends about Kihachi, including:

- He served Takeiwatatsu-no-mikoto and ran to retrieve his arrows during the god's target practice. He retrieved 99 arrows, but grew so tired that he retrieved the 100th with his foot. Displeased, Takeiwatatsu-no-mikoto cut off his head. The head rose into the sky and brought frost on the land until it was warmed by a bonfire.

- Onihachi lived in Chichi Cave at the foot of Mt. Nijou. He forcibly took Unome-hime (also known as Asara-hime), daughter of Inari-hime, as his wife and hid her.

- (From the Miyazaki Legends) Similar to the Takeiwatatsu-no-mikoto story, he angered Aso-myoujin of Higo by picking an arrow up with his foot. His wife Asara-hime, an incarnation of a dragon from Mitai, rebelled against him at the behest of Mikeirino-no-mikoto (Mikenu-no-mikoto), whereupon Tabe Shigetaka and others subjugated him, cut him into pieces, and buried the parts in three separate places.

- (From Takachiho) He was a demon who lived in a cave until he was killed by a son of Emperor Jimmu, who cut him to pieces and buried him in three separate places.

- (Also from Takachiho) His real name was Hashiritakeru, a giant spider. He ruled Takachiho, harried the people, and violently carried off beautiful women. He was exterminated by Mikeirino-no-mikoto, his body cut up, and buried in several places. He was described as a god who could make frost at will.

Also called: Kousaka Danjou Masanobu (高坂弾正昌信), Kousaka Danjou Nosuke Masanobu (高坂弾正忠昌信), Kasuga Toratsuna (春日虎綱), Kasuga Gensuke (春日源助)
Title: Danjou Nosuke/Faithful True-Shot (弾正忠)

Historically: One of Takeda Shingen's most loyal retainers who was one of his Twenty-Four Generals and played a key part in the fourth battle of Kawanakajima.

Kousaka was born in Kai to a wealthy farmer, Kasuga Ookuma (?) (春日大隈). His father died when he was 16, and he lost a lawsuit against his elder sister's husband for ownership of his father's lands. He then enrolled in the service of Takeda Shingen.

Kousaka first served as a messenger for Shingen. He distinguished himself in battle, and rose swiftly through the ranks of Shingen's trusted retainers. He participated in most of Shingen's battles. He did not hesitate to retreat when required, which earned him the nickname of "Escaping Danjou". However, he was calm and logical in the midst of battle, and was perhaps the best of Shingen's generals.

There are anecdotes that in his younger days, Kousaka and Shingen were engaged in a shudo relationship, and Kousaka rose so quickly in Shingen's service because of Shingen's affection.

After Shingen's death in 1573, Kousaka continued on to serve Takeda Katsuyori. He sought an alliance between the Takeda clan and their old enemy, the Uesugi clan, in order to unite against the threat of Oda Nobunaga.

Kousaka died in 1578 of illness at the age of 52. He was succeeded by his second son, Kousaka Masamoto (高坂昌元), his first son, Kousaka Masazumi (高坂昌澄) having died in the Battle of Nagashino in 1575.

In Mirage of Blaze: A kanshousha who, along with Sanjou-no-Kata, breaks the barrier over Takeda Shingen's tomb, the Maenduka, in an attempt to resurrect Shingen by using Narita Yuzuru as a vessel for his spirit.

According to Haruie, Kousaka has a high level of spiritual sensing ability (reisa), such that he is able to recognize someone he had met before even after their soul has undergone purification. He warns Naoe that Narita Yuzuru's existence is a threat to the Roku Dou Sekai.

Also known as: Kuranosuke—nickname (内蔵助)
Titles: Mutsu no Kami, Ecchuu no Kami, Chamberlain

A daimyo of the Sengoku, born in Owari. His father was Sassa Morimasa. His two older brothers, Sassa Masatsugu and Sassa Magosuke, died in battle, so Narimasa became head of the clan and master of Hira Castle in 1560. He distinguished himself in the loyal service of Oda Nobunaga and fought in many of Nobunaga's battles. His name was first on a list for the Kurohoro-gumi, an elite group of Nobunaga's bodyguards.

In 1580, he backed Jinbou Nagazumi against both the Uesugi Clan and the Ikkou-ikki in Ecchuu, and was given half the province. The following year, he was named governor (Kami) of the entire province when Jinbou Nagazumi lost his standing. He made Toyama Castle his main castle and performed extensive repairs and renovations on it.

After Nobunaga's death in 1582, Narimasa continued to engage in fierce battles with Uesugi Kagekatsu. He took the side of Tokugawa Ieyasu and Oda Nobukatsu against Toyotomi Hideyoshi, but later surrendered to him in 1585 when Hideyoshi laid siege to Toyama Castle with 10,000 troops. He lost Ecchuu, but was given a fief in Higo in 1587 for merits in the suppression of Kyuushuu, along with instructions on refraining from hasty reforms. Ignoring those instructions because of illness or perhaps misunderstanding, Narimasa immediately set out on Hideyoshi's nationwide land survey, resulting in rebellion of the province. He was charged with misgovernment and committed ritual suicide.

He wrote the following as his death-poem: "The shell of my begging bowl in which I have placed the evil delusions of these recent days now breaks" (この頃の　厄妄想を　入れ置きし　鉄鉢袋　今破るなり).

Narimasa is said to have brutally killed his concubine, Sayuri, along with her family for a rumor of infidelity. The legend goes that Sayuri cursed him before she died, and the curse was responsible for his death at the hand of Toyotomi Hideyoshi.

In Mirage of Blaze: He is kanshousha who has entered the «Yami-Sengoku» as one of the Oda's commanders, described as a tanned, fearless-looking young man, a "mountain cat in human skin." He and Mori Ranmaru don't appear to be on the best of terms. He later seeks his death at Sayuri's hands in remorse for the way he brutally tortured and killed her in their previous lives.

lit. "Heavenly Dog"

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. Beginning in the 13th century, tengu came to be associated with the mountain ascetics who practice Shugendou and are said to be protective spirits of the mountains and forests.

Orphaned son of courageous general Kiyama Masachika of Higo, he was a giant of a man recognized as a person of unrivaled physical strength, said to possess the strength of 75 men. He was one of the coolie workers who built Kumamoto Castle.

"Yokote no" is not a family name; it means "side/beside", so Yokote no Gorou is something like "Gorou at the side".
