Vesseless Demon
A vesseless Demon is a human that is unaware that there is pure demon blood in their veins, causing the effect of not being to be possessed nor attacked at a certain degree by other lower level demons. Be cautious though, There ability to copy others abilities, goes to the point of being able to copy moves that have been inherited by a rare clan or ancient master. Lower level demons are also recognizable in their presence, glamour or not, they make a small scent from demons reek.
