Monou Saya is the wife of Kyougo and the Mother of Kotori and Fuuma. She was a good friend of Toru's, and the two were constantly together. Kamui considered her a second mother. Six years before, Kotori and Fuuma discovered Saya torn to pieces in their home. The bloody scene resulted in Fuuma growing from a caring, open boy into an introverted young man. The seeds for Kotori's eventual madness were also planted at that time. Later in the series, Tokiko gives birth to the second Holy Sword in front of Fuuma and Kamui, and is torn to pieces in the same manner as Saya. Apparently Toru had been fated to give birth to the first Holy Sword. But, rather than allow Kamui to become and orphan, and out of love for Toru, Saya took Toru's place and gave birth to the sword. The same sword which her husband Kyougo died to protect.
Kyougo is the residing priest at the Togakushi (Hidden Sword) Shrine. Since the death of his wife Saya, he has protected the Holy Sword which Saya gave her life to birth. On the day which Kamui returns, Kyougo confronts Nataku who has come to steal the Holy Sword. The two battle, and Kyougo is amazed when Nataku withstands a direct blast from the Holy Sword, even when not wielded by Kamui. Unfortunately for Kyougo, the first Holy Sword is fated to be stolen, and it's defender predestined to die. Not matter how hard Kyougo fights, he cannot win. In the end, Nataku punches its fist through Kyougo's heart. Kyougo's last words are :
"The Holy Sword is...It... has... started...The first arrow... signaling... The End of this World...Has been...fired...Ka...mu...i... Take... back... the... Holy Sword...A kekkai... Before...the... Se...ven Seals...are... destroyed. Fuuma... You... are... Ka...mui's... (He dies)
Kotori is Fuuma's little sister. She has always been delicate, and has a heart condition. Like Kanoe, Hinoto, and Kakyou, Kotori possesses the ability to dreamwalk. Her dreams show the end of the world and two Kamuis. Kotori is a very sweet person who has always loved Kamui. Unfortunately, Kotori is too delicate to survive the trials which her brother and Kamui must undergo. The horrifying way her mother died erodes her sanity. When Tokiko dies in the exact same manner, Kotori is unable to cope, and she goes mad. The madness is short-lived, as is Kotori. Out of his concern for Fuuma and Kotori, Kamui choses to become a Seal, making Fuuma a Minion. Fuuma's kind personality is subsumed by the evil of the Dragon of Earth, and he eventually kills Kotori in front of Kamui, stabbing her in the chest with the Holy Sword her mother died giving birth to, and then causing her body to be ripped apart. Kakyou rescues Kotori's spirit, taking her place while Fuuma kills her, and enduring her pain for her. Her last words to Kakyou as her spirit flies off the Heaven are :
"Tell my brother and Kamui that I love them. I love them forever."
And Fuuma's profile is with the Dragon's of Earth.
