Truth Seeker Devianne:
Understood. Allow me to tell you what must be done.
The first thing is to take out the demons. It's a simple yet efficient way to stopping them from refinement. Death Rogue, Death Shooter, Death Warrior, Death Sorcerer, Death Pondus, Devil Nightmare, Devil Warrior, Devil Guardian, Devil Sinist, Devil Varos, Demonic Wizard, Demonic Warrior, Demonic Archer, Demonic Keras, Demonic Weiss are your targets. Hunt them down, collect 500 Demon Slayer's Proof and bring them to me.
