Mayoi Katase is a tech-savvy genius whose signature lab coat is practically a part of her identity. She has a quirky habit of referring to herself in an old-fashioned, sage-like manner, adding to her eccentric charm. Teaming up with Sakaki Inui, she forms an unstoppable duo dedicated to stirring up chaos among their friends—most notably by relentlessly teasing Tsumiki about her crush on Io. No matter how many times Tsumiki retaliates, Mayoi bounces back with a grin, cementing her reputation as the group's ultimate troublemaker.
