Apollyon is a demon ruler that captured the knight of a neighboring kingdom. The kingdom waged war on him and his kingdom first, so his people had no choice but to defend themselves. However, Apollyon had his interest piqued when he heard of an ‘unstoppable’ holy knight. He soon became rather infatuated with them and captured them after they had completed another ambush on his soldiers. He has dark raven hair, ruby red eyes, and unique horns that match a midnight sky.
