Sayoko Mishima is a villainess and Keiiji's former love interest from the anime Ah My Goddess.

History
Sayoko was once Keiiji's love interest, but she turned him down after he asked her if she could go to the museum with, telling Keiiji that going to the museum is for boring old people and saying she might reconsider going on a date with him if he grows a few inches taller.

However, Sayoko becomes jealous after she sees Keiiji with Belldandy, after Keiiji made a wish for Belldandy to stay by his side forever, making Sayoko jelous after several men who fell for her dumped her over Belldandy and tried to make her find a way to seperate Keiiji and Belldandy.

When class was starting, Sayoko wanted Belldandy, who was sitting next to Keiiji, to move out of her seat, but Belldandy came up with a way for Sayoko to sit between her and Keiiji. When the teacher of the classroom noticed Belldandy and said he never seen her before, this gave Sayoko the idea to go to the college professor to make him do a background check on Belldandy to see if she is an exchange student. Toriachi and Otaki heard about this, so they went to Keiiji and Belldandy to make them hack into the school's system to put down false information about Belldandy.

Sayoko, still not giving up, goes over to Keiiji and Belldandy and tells Belldandy that the college professor wants to see her. With her gone, she asks Keiiji about his feelings about her, but then water dumped over her as it was part of the system force that compels Keiiji from leaving Belldandy.
