Later, Keisuke follows Miaka to the library and watches her be re-absorbed into the "Shi Jin Ten Chi Sho". He then picks up the book and begins reading, following along as the stories of Miaka and Yui unfold. Keisuke is as cheerful and outgoing as his sister is, and is very close to and protective of Miaka. His main concern becomes returning both Miaka and Yui to the real world, as well as uncovering the mysteries surrounding the past of the "Shi Jin Ten Chi Sho".

Tetsuya is the best friend of Keisuke Yuuki. He meets Keisuke at the library, and because he refuses to stop annoying him, is eventually told the story that Keisuke’s little sister was pulled into a book. Tetsuya becomes the reader of the "Shi Jin Ten Chi Sho", while Keisuke busies himself doing research of the religion of the Four Gods and finding out the book’s past. Tetsuya is a fun guy who is rarely serious, but he is very concerned about his best friend and eager to help Keisuke get Miaka and Yui out of the book and into the real world. Tetsuya constantly wears a pair of sunglasses over his eyes, to emphasize his coolness, which he is never shown without.

Chuei Sou

Chuei is the oldest of Tamahome’s younger siblings. He looks up to his older brother a lot, and during Tamahome’s absences from home, he is the master of the household, taking care of his father, younger sisters and brother. Chuei runs the farm, making sure the fields are plowed, sown, and looked after. He also manages the money his older brother brings home to the family, making sure to spend it wisely only on necessary things. Chuei resembles a younger Tamahome very much, with long blue hair and grey eyes. Chuei is a noble young boy, who does his best to look after his family and take Tamahome’s place while he is away.

Yuiren Sou

Yuiren is Tamahome’s youngest sister. She is very small, cute, and innocent, and loves her oldest brother with all of her heart. It was shortly after Yuiren’s birth that Tamahome’s mother died, so Tamahome raised Yuiren himself. Yuiren is very sweet, and as a child, naturally curious and open. She calls Miaka "Neechan", and instantly picks Miaka out as a bride for her "Niichan". She makes little bridal gifts for Miaka, who she also loves very much, and wants nothing more than for Tamahome to come home to stay, and be with her always.

Emperor of Kutou

The Emperor of Kutou is a domineering, self-satisfied man who craves power and military strength. He is prejudiced against different races of people, and because of his discrimination, the Country of Kutou is in a state of constant unrest. He does not concern himself with peace or better politics; instead, the Emperor thinks only of his own pleasures. Though the Emperor puts on a facade of courage and control, in reality he is very weak and cowardly. He especially enjoys spending his time engaged in sexual intercourse, and is a social pervert. Also, the Emperor is a little too assured of Nakago’s loyalty to him.

Koji

Koji is nineteen years old, Tasuki’s absolutely best friend, and the leader of the Mount Leikaku bandits after Tasuki leaves to protect Suzaku No Miko, Miaka. Koji possesses a sharp attitude, as well as a straight and noble character, and is loyal to his friends. Koji has a very funny habit of knocking on a door, answering it himself, and then carrying on an entire conversation that way. Koji is also an excellent fighter, particularly good at swordsmanship. Koji is almost like a brother to Tasuki, the two are such good friends; and Koji would stick with and help Tasuki through all crises.

Eiken

Eiken is a member of the Mount Leikaku bandits, who steals Genrou’s position as leader while Genrou is away. The bandits’ former leader had died, and Eiken stole the treasured Tessen, using it as a sign of his power and authority over the other bandits, who had no choice but to follow. Eiken is very fat, ugly, and has a Lolita Complex (a sexual obsession with young girls). Naturally, when Miaka and the others travel to Mount Leikaku, Eiken detains them and tries to have his way with Miaka. Fortunately, Genrou returns from his travels, and with the help of Koji and Miaka, overthrows the nasty Eiken.

Shoka

Shoka is the daughter of a landlord in the village of Souen, near Choko, in northern Konan. She is the lover of Myojuan, but fell ill while he was away doctoring in other villages, and died before he could return to cure her disease. Shoka’s body was taken over right before her death by the evil demon, Shikkonki. This gave her the power to raise the dead, and she lived on as a very well-preserved zombie. Later, when Shoka began struggling with the demon inside of her, the people she supposedly had raised also became zombies under her power. When Miaka and the Suzaku Seishi informed Myojuan of Shoka’s presence, he came out of hiding and exorcised the demon, and finally Shoka was able to rest in peace.

Tama

Tama is a cat and Mitsukake’s pet. For a time, Tama was Mitsukake’s sole companion, before Miaka and the others met him. Tama is very cute, and he enjoys to follow and play with Miaka and all of the Seishi. Naturally, Tama loves and is loyal to all of his friends. Also, he has been known to mimic and imitate people; with impersonations that are nothing less than impressive.

Shifan

Shifan is the adopted daughter of the two Byakko Seishi, Tokaki and Subaru. Her father died a year previously, and she was taken in by the elderly couple. She is a good daughter to them, respecting their wishes and taking their helpful advice to her. Coincidentally, Shifan resembles Miaka, only with long dark blue hair and blue eyes. She is an excellent cook, and knowledgeable of the local folklore of Bakan village in Sailo Country. During the visit of the Suzaku Seishi at her home, Shifan’s adopted father Tokaki told her to comfort and be friendly to Tamahome, helping him to forget his love for Suzaku No Miko, Miaka. Being a good, obedient daughter, she does so, and as a result, is not on very good terms with Miaka.

Toki

Toki is a monk and the adopted grandson of Suzuno Oosugi, who takes care of her in her old age. Toki never believed Suzuno’s crazy stories about being pulled into a book and becoming the Byakko No Miko. Keisuke and Tetsuya arrive at the temple where Toki lives, and Toki is startled to discover that Suzuno’s story was, in fact, the truth, after hearing that Keisuke’s sister was the current Miko in the book. Toki helps to answer some of Keisuke’s and Tetsuya’s questions about the book, unraveling some of the book’s mysterious past. Toki helps Tetsuya read and research the "Shi Jin Ten Chi Sho" after Keisuke leaves to help Miaka.

Houki

Houki is the wife of Hotohori and the Empress of Konan Country. Hotohori married Houki sometime in between Miaka and the other Seishi leaving for Hokkan and returning from Sailo. Houki is very kind and gentle, and loves Hotohori with all of her heart. Supposedly, Hotohori met Houki after feeling a blast of Chi from Nuriko’s death, and believed that Nuriko had brought them together. Houki looks almost exactly like Nuriko, so that the first time Miaka sees her, she mistakes Houki for Nuriko and immediately rushes to hug her. Later, Houki becomes pregnant with Hotohori’s child.
