Also known as: ネジ柳ユーコ
Nejiyanagi Yuuko is a character in Heybot! who parodies Yamamura Sadako from The Ring. She has long Black Hair that covers one eye, Green Eyes, and usually wears a white Dress with a green screw as a Necklace. She is often depicted with Sharp Teeth. She is sometimes depicted with Half-Closed Eyes, and other times with wide crazy Empty Eyes with No Pupils. She's often coupled with Kowakowatto Natsuo.
Later in the series he forms the basis and/or alternate persona for several additional characters in the series including Pluto (Heybot!), Furuido Yuuko, and Vocamente Yuuko.
