The white-faced rough-tailed ape in "The Book of Mountains and Seas" is described as an ape-like mythical beast with a white head, gray hairs on its limbs and body, and a thicker tail with hair.
It lives in deep mountains and dense forests, is very wary of humans, and is extremely ferocious. Legend has it that it can imitate human language, but it can only speak simple words and is often mistaken for humans by humans, so it is also called "ape-man". It is good at climbing and jumping, is extremely fast, and its strong muscles give it a strong attack power. It is one of the overlords in the mountain forest.
