From Demon Slayer (Taisho Era) ~ Doma is the UM Two of the Twelve Kizuki; the third most powerful demon in existence. He's the leader of the Paradise Faith Cult created by his parents. Despite this, he's a misanthropic atheist, believing the universe is cold and that only a fool has faith in gods. Doma was born 200 years ago, turned into a demon by Muzan shortly after his mother had murdered his father. He has no capacity for emotions and wears an affable facade to compensate.
