Species: Phantom

Phantoms (幽霊, yūrei) are spirit entities often confused with ghosts. However, all ghosts are the spirits of dead people, whereas phantoms may not be; many are born as phantoms from the start. Conversely, multiple phantoms can come from one body and they may originate from beings other than humans. Phantoms possess some common characteristics, being intangible and known for their freezing temperature which can be used to one's advantage in hot weather. These are the blobby white "ghosts" that populate the Netherworld as well as other realms and systems of the afterlife.
They are also similar to poltergeists, though those too are technically different.
