Ghosts

"" are the spirits of deceased people who have not yet been able to go to the afterlife. In order for them to go there, they have to resolve their unfinished business or unresolved issues.

Physical Appearance
Physically, they look the same as they did before they died. However, they get more pale or even transparent in their normal ghost forms, and some variations in their appearance (black sclera, etc.) are present.

Powers and Abilities
Ghosts, in general, can hide their ghostly nature and take on a human form, but they will look pale in response. They also have the ability to fly without the need of wings.

Weaknesses
Unlike classic ghosts, the ghosts featured in the series can't go through walls if they have not been invited by the people inside the walls. They're also weak to iron.
