Yokosawa's appearance is based of the Axolotl, specifically the White Albino morph. She has light pink skin, peach external gills, and a transparent caudal fin. Yokosawa wears the typical accounting office uniform consisting of a matching blue vest and skirt, white dress shirt, and black shoes.
Yokosawa is very perky and loves to talk. She is renown for interuppting others while they're talking to her with sudden thoughts and topic changes irrelevant to the conversation.
