Vampire demon form

The energy that covered the planet, the energy that seeped in from the land of the dead, would usually continuously move towards those of the living. It was naturally attracted to them to a certain degree and the inhabitants had always been taking in this energy bit by bit. 

For the ones known as the demon kings, as well as Immortui, they were able to control this energy and harness it to be used in a certain way. Almost making their body like a magnet that would attract the energy.

However, the moment Kronker, the Durum demon king, unleashed the powerful energy from within, his body started to transform. The energy was leaking out of his body, and it looked almost as if the energy in the air was frightened, attempting to move away. 

Yet, the demon energy being unleashed was consuming everything within sight and it was growing.
