In his first four appearances, due to his posing as a villian, Kido had a very arrogant attitude. He remained very cool and "evil" in the episodes where he had Yusuke captured, often mocking him and the power he held over the frozen detective. When he was revealed to have been just acting like a calculating villain and really was a good guy undergoing training from Genkai, Kido's personality changes to a polite, reserved, and somewhat soft-hearted young man who cares about his city. Generally, in public, Kido puts on a facade of an arrogant thug, and acts like he is powerful and intelligent, but when he is isolated with his friends, Kido acts in a friendly and sociable manner. He is rather apologetic, immediately begging for forgiveness to Yusuke for hurting his friends the moment the facade was over, revealing that he did not want to harm them (in the English dub, this was changed to Kido apologizing to Genkai for failing to defeat Yusuke's group). Despite his hesitant nature, he does become resolute when lives are in danger.
