Cock Robin didn't move from his spot. He had expected such a rash reaction. It was the man's loss. For, as the venosaber sliced through the air, in the instant before it reached Cock Robin-
It "evaporated", ceasing to exist. Ouja's weapon had been utterly unmade. The Ploy stood where it had before, unharmed. The attack had never "reached" the Ploy. It had not been allowed access into its world.
This Ploy, designed for the sole purpose of "being cute," a being who certainly lacked the destructive capability to break the venosaber, had unmaked it by existing.
This does not seem possible. It defies logic, and that is precisely why it had happened.
The hero Heracles possesses a Noble Phantasm called God Hand. Closer to a conceptual weapon than a Noble Phantasm, and closer to a conceptual space than a conceptual weapon. Within that conceptual space, "attacks of B rank or lower are nullified." There is no exception, no loophole. Even if an attack that destroyed the multiverse struck Heracles, were it "B ranked" he would be completely unharmed.
The Ploys operated in a similar way. They lived in a conceptual space, in their "own world."
Within their conceptual space, "technology" and "Magecraft" were meaningless. A burst of magic power, firing of a laser, or even some twisted combination of the two were utterly irrelevant.
They were fairy tale creatures which existed in their own world, defying logic and reason simply by existing.
Thus, no matter how far technology or magecraft advances, no matter how great it becomes, it will never be allowed to enter the fairy tale world of a Ploy.
This was the power of the First Witch, drawing its roots from a time before even the first hero's story.
Even the legendary weapons of something such as Gilgamesh's Gate of Babylon would be denied access.
Even things that attempted to be irrational such as "emotion" were denied.
It was not that the Ploys were "stronger" than these things inherently, no, it was simply that the Ploys found these things inconsequential.
The Ploy was a perfectly impossible existence. No matter what occurred to it, it would exist in its world without a care about the weapons fired at it.
And so, after the blade had evaporated, Cock Robin spoke up again.
"You're a temperamental one, aren't you?"
