Kyogai is a relatively quiet, nervous and soft-spoken person, despite being a bloodthirsty demon. Rather than scream or roar when annoyed, Kyogai quietly murmurs about whatever is irritating him. He believes it's rude for people to barge into his home and will destroy them for getting in his way. If irritated enough, Kyogai will raise his voice about the nuisance and insult his opponents.
