Katie is a kind and playful person. She's very popular and often considered cute with a certain charm. When bewitched by Yo-kai, she usually retains her cheerful demeanor but can come off as unintentionally cruel though she seems to never recall these incidents. She's also smart, but also worries about meeting her mother's standards. She is surprisingly brave and comfortable with heights. It also seems that Katie is extremely oblivious whenever it comes to romance.
