"Stella Watson" is one of the Buddy Police's operators. She is English, but was raised in Kyoto. In the Japanese version she sometimes speaks in Kyoto-ben.
She has blonde hair, tied to a bun with some streaks down to her front right shoulder. Her eyes are turquoise-blue and she wears spectacles over them. She wears a green vest (probably?) over a white-grey shirt. She has black high heels. It ends with a skirt the same white-grey color.
She is a confident and calm girl, and likes to make new friends. She is very loyal to the Buddy Police as she does lots of things to help them.
