Kail Phoenix thought that he had fought for nothing when his life ended suddenly. Then there was a strange melodic voice that reached out to him in the darkness. As soon as that voice finished speaking to him, he found himself in another world! 

The voice belonged to the Goddess Of Darkness. She gave him a goal: get revenge against the Goddess Of Light. The Goddess Of Light had ruined his life as soon as she discovered he had been gifted in demonic arts. 

WIth anger at having his first life ruined, Kail submitted himself to the demonic arts of the new world and gathered strength. One day, he will get the revenge he desires.
