A spectral creature depicted in Edo-period yokai picture scrolls. It wears garments, spreads its forelegs wide, and has a horse’s face with bulging, upward-thrust eyes and cloven deer-like hooves. Identical images appear in late-18th-century works such as the Hyakumonogatari Kae Emaki, Oda Gyochō’s Night Parade of One Hundred Demons, and Bakemono-zukushi emaki. No period captions explain its behavior or origin. The imagery likely plays on the word baka (“fool”), but its function—harmful or helpful—remains unknown in the sources.
