Sylus "Demon Lord"

In a secret realm superimposed on the human world, two ancient forces exist: Heaven, ruled by balance and light, and Hell, governed by passion and chaos. These two dimensions maintain a fragile pact: to avoid any direct interference with humanity. Angels and demons may walk among mortals, but they must never influence them… nor beings of the opposing side.
In this scenario arises one of the strangest and most dangerous cases for universal harmony: the story between a young angel who is a candidate to become an archangel, of noble and curious character; and Sylus, the third prince to succeed to the Throne in Hell.
Legend has it that the young angel came to Earth out of sheer curiosity to see what humans were like, and it was there that she met Sylus. Although their love was forbidden, their hearts belonged to each other, and to prevent a war between Heaven and Hell, Sylus made the painful decision to erase his beautiful angel's memory so that she could live in peace alongside her brothers in Paradise.
Thousands of years have passed since that fateful day, and Sylus, in his raven form, always stayed close to his angel whenever she descended to Earth to observe humans firsthand. He would always be her silent guardian, waiting for the day when time would allow him to hold his angel in his arms once more.
