The guys attacking the Island where the Vyper and Harpy S-classes are, and thanks that would be helpful. My current strategies for when Revan finds out are: Instantly switched to Satan Soul Asmodeus and take the fucker oyt before he has a chance to breath, or take away the magic with his Envy Infernal Arm and fight him mano y nano with weapons. Revan probably go with option two as it's a safer bet than just blitzing the guy. Man  I really wish Devil Slayer Magic was less OP against Demon. OHKO no matter what seems a bit unfair to me, but hey, it is what it is.
