Kagaya has light skin and Black shoulder length hair. He has a curse mark that is slowly killing him that also makes his skin look as if it was rotting spreading down his face and covering his eyes making him unable to see, by the time of his death this curse had spread all over his body making moving nearly impossible. Muzan at Kagaya's death described him as having the smile of a Buddha
He usually wears a black Kimono with a long white kimono jacket with a pink and purple mist like pattern that starts around the lower back/waist
Abilities and Powers
Foresight: In addition to his special voice, Kagaya (and the rest of the Ubuyashiki family) possessed a heightened level of instinct that could help them avoid disastrous situations and amassed them a great amount of wealth and fortune,due to this instinct Kagaya has accurately made several guesses about multiple things that were eventually proven to be true and accurate without any prior information, as seen when he accurately guesses that Muzan's only remaining weakness was the sun and could not be destroyed by the Decapitation,and again when he accurately guessed that the Deaths of Gyutaro and Daki,would send waves that would eventually see that the Upper Moons of the Twelve Demon Moons begin losing members for the first time in hundreds of years.
