Doma can be best described as an entity of pessimistic nihilism itself. Doma is a psychopathic, deranged, ruthless, misanthropic and manipulative nihilist who pretends to be outwardly friendly. He is the Demon that most resembles Muzan Kibutsuji. Doma is a complete and utter psychopath who is hopelessly unable to comprehend basic human emotions. He admits that even during his human days, the entire concept of emotion itself was alien to him. He has a cynical view of the world.
