The Demi Emperor

The Demi Emperor - known to 13 as the Promised One, 12 as the Unknown One, and to Lord Kane as The Cursed One- was a Demi human from Osaka, Japan, Earth. He formed The Demi Empire and would begin to accumulate and manipulate his way into forming an extremely powerful Demi Faction. 
Born in "xxx" BSI to a high ranking Japanese nobel family, "xxxxxx" would discover his Demi Power at the age of 4 and began using it to manipulate those around him. This manipulation would continue, until his older brother "black flame swordman" discovered what he had been doing. Punishing him, his brother sent "xxxxx" to scale a mountain as punishment for his actions. While scaling the mountain, a large snowstorm began and "xxxx" had to find shelter within a cave. However, while in the cave it suddenly lit up with an azure light; from the light came the Demi Guardian Qing Long (青龍), The Dragon of the Azure Flame. Recognising "xxxx" as his equal, Qing Long pledged himself to "xxxx", releasing what power he had come upon, "xxxx" proclaimed himself the true heir of Demi kind
Upon the end of the snowstorm, "xxx" left the cave with Qing Long and set of to get revenge against his older brother. Upon reaching home, "xxxx" challenged his older brother to a duel. As the duel began "xxxx" was confident in his victory, however this confidence disappeared soon after, when his older brother revealed the Demi Guardian, Xuan Wu (玄武) ,The Turtle of the Black Flame. "xxxx"'s brother swiftly defeated him and Qing Long, and banished them back to the mountain. As the defeated "xxxx" was leaving, two loyal members of the house followed him, one a demi and the other human. Upon reaching the cave, "xxxx" told the two followers that he would get his revenge and noble status back, proudly stating his new title, "The Demi Emperor".
