Dimension eater

With a thunderous roar, the giant two-headed quicksilver-colored dragon assailed her.
The golden light that enveloped the angel’s body grew in radiance. This was the light of the divine aura flowing in from the upper planes.
Enveloped in this radiance, Faux-Angel was simultaneously in the world, but not of it. Even the incredibly destructive might possessed by a Primogenitor’s Beast Vassals were unable to bring harm to an otherworldly angel…or so it should have been. But…
“It’s not possible…!”
Kensei Kanase raised his voice in horror at the impossible scene unfolding before him.
Kojou’s quicksilver-colored Beast Vassal was consuming the very golden light that enveloped the angel’s wings—wings it should have been unable to even touch. Faux-Angel cried out as light gushed out in place of blood.
“It…consumed Faux-Angel’s Extra-Dimensional Membrane?!”
Before Kensei’s shocked eyes, Faux-Angel lost one of its wings and fell.
But the two-headed dragon’s assault did not relent. From the front and back, top and bottom, left and right, its two maws assaulted, whittling the golden defensive membrane down.
As Kensei beheld this, he finally realized the true nature of Kojou’s Beast Vassal.
“That Beast Vassal… It’s a Dimension Eater! It can consume any space and the dimension along with it?!”
Indeed. It looked every bit as spectacular as the lightning lion, every bit as wild as the incandescent bicorn. But in pure fiendishness, the quicksilver-colored two-headed dragon was head and shoulders above them.
It was a Beast Vassal that consumed, so to speak, the very world itself, dealing unrecoverable damage. It was the mortal enemy of those beings of creation known as “gods.” Surely, it was the most horrible, most accursed of all Beast Vassals.
