Taizō Kirihara
Taizō Kirihara (桐原 泰三, Kirihara Taizō}) is the founder of Kirihara Industries, (桐原産業, Kirihara Sangyō) and leader of the Kyōto House. He is an elderly industrialist who built his wealth upon the mining of sakuradite. During the Kururugi Administration, he used his considerable influence to support the government as a behind-the-scenes administrator. He was regarded as a traitor to the Japanese people following the Britannian invasion for his public role as an accomplice to imperial colonization. Secretly, however, he manages resistance movements against the colonial government. He came to know both Lelouch and Nunnally while they were living at the Kururugi Shrine, and, in knowledge of the circumstances leading to Lelouch's assumption of the identity of Zero, he grants the Black Knights vital funding and weapons. After the Black Rebellion, he is executed for supporting the Black Knights.

Kaguya Sumeragi
Kaguya Sumeragi (皇 神楽耶, Sumeragi Kaguya) is the young head mistress of the Kyōto House, and a supporter of the Black Knights. Despite her age and physique, she possesses a strong will and is highly influential amongst the Houses. Kaguya has admired Zero since his debut, and wishes to have his hand in marriage. Nothing anyone says contrary to this desire seems to faze her, including the suggestion that Zero might be sleeping with other women, to which she responds "A true hero enjoys physical pleasures," and proceeds to suggest that she, Kallen, and C.C. are Zero's harem. Kaguya met Lelouch and Nunnally during their childhood at the Kururugi Shrine, and is Suzaku's cousin. She is the only living member of the Kyōto House following the Black Rebellion, having managed to escape to the Chinese Federation until Zero's return one year later. She is named after Kaguya.
