A True Celestial

So this is my first attempt to write a story about the personal fantasy world i had created in a 2 year depresion period in order to escape my harsh reality (cliche i know). We see through the eyes of Leon,an average guy in his late teens who attempts suicide. In his last moments Dest,a demon on the run beaten almost to annihilation by the high angel legion ,possesses Leon body as his last resort. The rules state that any celestial being can't interfere with the human world directly. Leon desires freedom by death and Dest his revenge against all the celestials. A pact is made between the human and the demon:Leon can die only if he assists in Dest's master plan. Why does one desire death, one the disappearance of his kin, what's the master plan and the dark truth about the celestial world? Read to find out of course ;). Any comment and criticism is welcome of course. Any advice to make the story telling better will be revised. Have fun - Destriver
