Wing Manifestation is the power to make wings sprout upon one's back. The users ate also able to make them disappear at will.
This ability allows the users to make wings appear and stretch across their back, as well as conceal them by shrinking them until they vanish behind their backs.
This power also seems to not damage clothing and potentially could grow to allow the user to gain flight.
- As Gideon and Levi are from the television show, Heaven's Vice, the only use of this ability currently is not in-universe.
