Kitarō is usually cool and collected, but he also has a strong sense of justice and can be very passionate. Because of this, he has a good-natured side that can't ignore the plights of people or Yōkai. He even forgives Shūichi Yamada for transforming him into the Dai Kaijū. Despite this, he is initially shown to be quite cold and antisocial towards humans. Under the opinion that too much exposure to yōkai is not good for humans, he tries his best to avoid the human world as much as possible.
