She doesn't chant, so it is difficult to tell if it was Jiwald or El Jiwald, but the quote doesn't suggest she used the light sabers either, it just says "The ten white lights that had attempted to intercept Abel".
Ascertaining that, the final remaining Sphinx quickly readied both of her hands, produced ten swords of light from each set of five fingers, and this time, she attempted to mince up Subaru and his friends for sure.
Because of that, she did not even realize that she had taken her eyes off of the one person whom she absolutely should not have taken her eyes off of.
Vincent: [――Come forth, Yang Sword Vollachia.]
A quiet, yet dignified voice, one reliable to an aggravating extent, sounded upon Subaru’s eardrums.
No matter the tumult, no matter how many people were present, no matter how harsh a battle was unfolding on the battlefield, that man’s voice would always unquestionably reach its desired target.
That was the kingly caliber of the one who stood atop all others, shouldering the destiny of guiding their way.
As if to prove that, dazzling the eyes of all those present, providing a red illumination was――,
Sphinx: [――I thought you were not supposed to have that in your possession.]
Vincent: [Fool. ――Never once have I said that I had relinquished the Yang Sword or any act of the like.]
Only, the treasured blade of crimson which he had not drawn once, no matter what hardship had stood in his path, merely for the purpose of drawing closer the opportunity for victory in this moment, he now drew out from the sheath of the sky.
And then――,
Subaru: [This battle of trickery, is our win.]
Vincent: [The stratagems of my two strategists. ――You have underestimated them.]
Bearing the pain, Subaru took pride in their victory, and Abel took pride in the victory of the capabilities of the strategist who was not present here, the one who had devised the plan that had made even the Witch firmly believe that Abel had lost his trump card.
――The next moment, with Yang Sword in hand, Abel kicked off the ground, and leapt.
That was the dash of one who possessed definite strength, incomparable to the Abel up until this point. As the owner chosen by the Yang Sword itself, he was propelled to a dimension befitting that status.
To be precise, as if the world was being illuminated by sunlight, Abel forcefully raised the treasured sword overhead――,
Vincent: [――The Yang Sword cuts what I decide to cut, burns what I decide to burn.]
Sphinx: [――――]
The flash of crimson ran diagonally, and without any resistance, it burned away Sphinx’s ten white lights that had immediately tried to intercept Abel.
