Ībwa is an evil spirit, who once mingled with the people in human form. Due to the thoughtless act of a mourner at a funeral, he became so addicted to the taste of human flesh, that it has since then been necessary to protect the corpse from him. He fears iron, and hence a piece of that metal is always laid on the grave. Holes are burned in each garment placed on the body to keep him from stealing them.
