Earth is plagued by spiritual beings called Demons. These creatures come in the form of spirits, and ghosts. They enter into one's dream, forcing their victims to live their worst nightmares, or in certain cases, become the most carnal version of themselves. Alexander Kilton is a young man with a dream. Ever since he was little, he wished to join the military so he could protect his sister and the little children who are under the care and tutelage of his adoptive father. However, on the day he decided to join a competition being held in his town, he somehow gains possession of an ultra-powerful item: The Dark Core. The Dark Core is the pendant a well-renowned scientist named Saliel Cone used to defend Earth against the Demonic Race. At his last stand, he was forced to use the power he wished he didn't have to. The Pendant turned Alexander into a Demon, leading him down the path of death, destruction, and Demonhood. Alexander is forced to abandon his childhood dreams in pursuit of what is best for himself, as well as his little sister and his childhood friend. _________ Updating Schedule: 14 Chapters/week.
