Koto is a young woman who works at Yamaishi’s Bar, where Yajiro and Rushuna briefly stay while they are passing through Tara. She is a great admirer of King Furon and wears a pendant that she received from him when he visited the bar. Koto prepares a medicinal bath for Rushuna to help her recover from the wounds inflicted on her by Furon in his armored suit. The Jester injures her, which provokes Rushuna into attacking Furon's castle. In the manga, she was instead accidentally killed by Jester, who took the blow which was intended to Rushuna but dodged it.
