A dying patriarch who trades his life to secure humanity's dawn.
Kagaya Ubuyashiki is the 97th leader of the Demon Slayer Corps, an organization his family established. He is a distant relative of Muzan, resulting in his bloodline being cursed with a disease that slowly kills them before reaching their thirties due to their connection with Muzan's blood.

Reader's Guide
Kagaya Ubuyashiki serves as the spiritual and strategic leader of the Demon Slayer Corps. Though physically weakened by the curse afflicting his bloodline, he commands absolute loyalty from the Hashira and all slayers. His leadership style combines gentleness with firm resolve, earning him deep respect. He delegates authority to his wife Amane, who takes his place during Hashira meetings when he cannot attend. His children also assist: Hinaki and Nichika serve as his aides, while after his death, Kiriya leads the Corps alongside his surviving sisters Kuina and Kanata. Kagaya's ultimate contribution is his suicide bombing strategy, which exploits Muzan's personality to create an opening for the final assault. Following Muzan's death, Kiriya officially disbands the Demon Slayer Corps, as their mission has been accomplished.
