Daedanhan Vincent

A priest who lost everything to demons — Vincent Burns. Blinded by rage, he took vengeance on the demons through brutal violence and was eventually expelled from the Church. Years later, demons plotting to turn the world into a living hell set their sights on a young girl named Taylor. With no other options left, the Church entrusts their final hope — the dangerous outcast, Vincent — with the mission. Now stronger, crueler, and far more relentless than before... his exorcism begins once again.
