This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Katawa-guruma (Japanese)
Instead of a giant monk’s head stuck in a wheel, a katawaguruma appear as tormented, naked women riding single, flaming, ox-cart wheels. They suffer eternally, burning in pain. Katawaguruma look and act in much the same manner as wa nyud?, rolling along the roads of Japan, occasionally stopping in towns to hunt for impure souls to drag back to their hellish masters.
In a certain village of Koga-gun (Koga County), Omi Province, an oxcart on one wheel engulfed in flames, with a woman on itself, was on the prowl almost every night, and those who saw it, or even those who just rumored about it, were said to be cursed, so people refrained from going out at night and tightly shut the doors of their houses.
