Mahavairocana is the Cosmic Buddha who represents the center or zenith and is especially important to the Shingon school of Esoteric Buddhism. He was worshiped in Japan from as early as the Heian Period, and his Mahavairocana Sutra forms the basis for the rituals of the Shingon School.

Dainichi's characteristic hand gesture is the index finger of the left hand clasped by the five fingers of the right, symbolizing the unity of earth, water, fire, air, and spiritual consciousness.

Head of the Ichimata Clan, which was descended from the third son of Ootomo Yoshinao. He initially served Ootomo Yoshiaki, and after his death in 1550, his son Ootomo Sourin.

Sourin ordered the deaths of Akizane's father Ichimata Akisuke and uncle in 1553, at which point Akizane succeeded as head of the family. He continued to serve Sourin without rancor, and won several battles, making his military reputation. He put down a rebellion by another uncle in 1568 and fought against the Mouri in 1569 at the Battle of Tatarahama. He spent much of his life fighting for Ootomo but was ordered commit suicide in 1588 by Ootomo Yoshimune due to a rebellion of the Ichimata Clan.

Note: Mirage gives the reading of his name as Ichimanda Akizane; "Ichimanda" appears to have replaced "Ichimata" as the favored reading in modern times.

Historically: In the Sengoku era, he served three generations of the Nagao Clan: Nagao Tamekage, Nagao Harukage, and Uesugi Kenshin and was master of Hirabayashi Castle. He was one of Kenshin's most respected generals and Kenshin's military chief of staff. He was killed at the siege of the rebellious Honjou Shigenaga's castle.

He is the only one out of the five Yasha-shuu who survives the battle with Oda Nobunaga thirty years before the start of Volume 1, and carries on the mission alone while the others are reborn. He is a baby when Naoe finds Kagetora again thirty years later, having only performed kanshou two years previously.

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: "onii-san (お兄さん)", "onii-sama (お兄さま)", "onii-chan (お兄ちゃん)", "nii-sama (兄さま)", "nii-san (兄さん)", "nii-chan (兄ちゃん)"

"Older brother"—one of those very simple terms which is unfortunately difficult to translate because of the differences in usage between English and Japanese. In Japanese, it is much more natural to call your (older) brother "nii-san" or "onii-san" rather than by their given name. It connotates a degree of respect and at the same time a certain closeness. ("Onii-sama" indicates more formality, "onii-chan" indicates less familiarity.) This is the same reason most children in both cultures call their parents "Mom" and "Dad" instead of by their given names.

One can also use "onii-san" to refer politely to an unrelated slightly older male.

Lit. "rend-exploding exorcism"; a type of choubuku which uses the incantation "ari nari tonari...." Described as gun-like, as opposed to kouhou-choubuku.

Lit.: "ceremony god"; spirits summoned through ceremony to do the bidding of the summoner, much like familiars.

One of Akechi Mitsuhide's inner circle who dies in the attack on Kokuzou Shrine.

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".
