Character from Demon Slayer by Koyoharu Gotouge
Kagaya's eldest son — an eight-year-old who inherited command of the Demon Slayer Corps after his parents' suicide bombing and directed the final battle against Muzan from a war room.
Kiriya was prepared for command before most children learn arithmetic. When both his parents died destroying the Ubuyashiki estate with Muzan inside, Kiriya assumed control of the Corps' tactical operations — directing Hashira deployments, coordinating information flow, and making life-or-death decisions while barely old enough to be left unsupervised. He cried once, privately, then returned to the command room.
Very young — appears around eight years old. Short black hair. Resembles his father with the same gentle features. Wears white robes. Despite his age, his expression during the final battle is focused and controlled, mimicking his father's composure through sheer force of will.
