Kofuyu

A Yuki-onna who works at a ski resort. She invited Yuto and the girls to her ski resort to stop Tama, as she, like Yuto, wanted humans and ayakashi to coexist. It is revealed thet two years prior to the series, the ski resort's owner (and his wife) found her unconscious during a mild winter and nursed her back to health. She has also taken quite a liking to Yuto, once flirting with him in an onsen underneath the ski lodge and referring to him as "Yuto-sama". As a Yuki-onna, she can control ice and snow and use it to trap her opponents, once doing so against Tama in her adult form. Her name means "Little Winter", in reference to her ayakashi species.
