At the beginning of Wave 1 the Dark Slayer fell into trollehmot's trap and was forced to lose a duel in which his soul was lost 
But the slayer was not an easy pray and was able to control his mind after losing his soul, hence why sartorius got him out of the wave one to brain wash him.
He is now brainwashed and plays for Sartorius as the light side's strongest weapon.
Prepare yourself ordinary fellas, you'll meet your end ._.
