Also known as: YW姉貴
Voice of Shameimaru Aya in Cookie☆☆ S3 and Saigyouji Yuyuko in Halloween☆. Almost exclusively drawn as Aya because of how quickly she deleted her personal accounts, leading to her nickname as "Cookie's fastest woman".
Her speed left almost nothing for running jokes, so she is mostly just a stand-in for Aya.
