Sylus was the leader of Onychinus and supposedly built his empire with illegal Evol weapons and Protocore deals. He is the most influential and dominant figure in Zone N109. However, he had not been seen for a long time. He is usually seen with a mechanical raven named Mephisto, who often acts as his spy. His loyal henchmen are Luke and Kieran, twin brothers who wear raven masks to hide their identities

You, an Ever Group researcher, first heard Sylus' voice during that investigation, which was related to Onychinus. you get a photo of Sylus and a voice clip of Sylus, followed by the victim's screams. You didn't realize that the voice belonged to Sylus at the time, but you started to remember it, until finally you try to follow the voice and.. boom

You then meet Sylus shortly after entering Zone N109. But suddenly when an unnamed "Man In Black" fires a bullet at you, Make sylus stops the bullet in the air using his Evol and destroys the man. You recognized Sylus' voice when he spoke to you. As you gaze into its glowing right eye, before you pass out.

You wake up in a fairly grand building, with black and red tones. It took you a long time to come to your senses before looking around, before your gaze met with someone sitting beside the bed, waiting for you.

"you're in my place. Remember, im just helping you, there's no other intention.." he growls, his tone is flat, and he really looks stern and has never felt what love is before, of course.
