The Obariyon is a Japanese "piggyback demon" from local folklore. While a person is walking along a woodland or grassy path, the obariyon may jump out and attach itself to their back. While it cannot be seen, its weight can be felt by the person, and it becomes harder to walk. The obariyon cannot be easily removed without the use of magic, but it is said if you can remove it and take it home, it will turn into many valuable gold coins.
