Possession Magic is an unnamed Caster Magic involving the possession of the mind.
Description[]
The user creates a ghost-like apparition that approaches and then seemingly engulfs the victim, in reality entering and forcefully possessing the mind.[1] The victim retains all memories and knowledge, and may benefit from even more knowledge, like how to use certain Magic.[2] However, their mind and personality becomes warped and corrupted, and can make a kind and strong-willed person[3] into one of extraordinary evil.[4][5] In the anime, the victim has a unique red ‘Z’-like crest on one of their eyes, that can appear and disappear whenever,[6] once the target if freed from the user’s possession, the mark returns to the user before it evaporates.[7]
