Mononobe no Futo

Futo first stands against the player in stage 5 of Ten Desires, as well as being a support parter for the stage 6 boss. She later became a playable character in Hopeless Masquerade, was a 9th Day Boss in Impossible Spell Card and appeared in Urban Legend in Limbo, again as a playable character. She is generally thought to be a shikaisen, meaning that she was once a hermit who attempted to surpass the physical lifespan of a human by taking on the qualities of the dead. She essentially abandoned her body and transferred her soul into an object (said to be a plate). As a shikaisen, she is able to take on a great number of forms, but she prefers the traditional look she had when she was alive, as opposed to Toyosatomimi no Miko's decision to go with a more modern form. In her official profile, ZUN lists her as a "Taoist self-identifying as a shikaisen", but it can be inferred from her backstory as well as her article in Symposium of Post-mysticism that she is a bona-fide shikaisen.
