Kagaya Ubuyashiki, known as “Oyakata-sama,” is the 97th leader of the Ubuyashiki family and the head of the Demon Slayer Corps. Despite his frail health due to a hereditary illness that leaves him bedridden and blind, he possesses a charismatic presence and a unique voice, termed “1/f fluctuation,” which uplifts and calms those around him. His leadership is marked by wisdom, empathy, and a deep commitment to defeating Muzan Kibutsuji, the demon responsible for his family’s curse. Kagaya’s ultimate sacrifice, using himself as bait to lure Muzan, underscores his dedication, boosting corps morale posthumously. His age at death was 23, and he was married to Amane with five children, including his successor, Kiriya.
