This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Datsue-ba (Japanese)
Datsueba is often depicted sitting by the Sanzu River in literary, visual, and religious depictions of the Buddhist underworld. Although Buddhist hell is imagined in a great number of texts and images ranging from places such as China, India, and Tibet, Datsueba appears to be unique to Japanese iterations of Buddhist hell. Throughout these depictions, Datsueba is broadly imagined and illustrated as an old, frightening ogress who takes the clothes from the deceased as they cross the Sanzu River.
According to Japanese Buddhist folklore, when a child dies its soul has to cross the Sanzu River. Traditionally, when a person dies, it is believed that they can cross the river at three different spots depending on how they lived their lives. Since children have not accumulated enough experiences, however, they are unable to cross. At the river's edge, the souls of deceased children are met by Datsue-ba.
