"Oh that's just bullcrap." Rutger said, clenching his fists angrily. "First of all, Demons are just as mortal as you or I--there's a whole colony of them on Garuna Island, for instance. The Etherious demons, however, aren't even natural. The books they came from were created by Zeref. Maybe the reason for you being able to do that is rooted deeper in the origins of God Slayer magic, since it's not known whether or not actual gods handed it down, but Devil Slayer magic being higher in heirarchy isn't logical. As for being immune to an element, ALL Slayer types are like that--A Fire Dragon Slayer could eat regular flames just as easily as I could. The only time they're not immune--the borderline, as you put it--is when facing another Slayer."

But then Rutger clenched his fists again, producing black flame on both of them. "But rather than stand here and argue with you, I'll just do this!"

He punched the ground with both hands, and once again his flames exploded...but this time, it wasn't the flame attacking War.

"[b][color=black]Fire God's Frag Grenade![/color][/b]" Technically, this wasn't a real spell he'd learned from the book. Rutger had come up with it just now on the spur of the moment--but he could see no reason why it wouldn't work.

When the flames were punched into the earth and blasted it apart, large pieces of stone shrapnel were thrown towards War, tearing apart the ground beneath the two mages' feet. Propelled by the force of the blast, but not made of fire, the rain of earth shot towards the Devil Slayer like a supersized shotgun blast.
