"Yvaine! Now!" Vale's urgent cry prompted Yvaine to materialize near the Demon Saint.
Her previously concealed presence, shrouded in darkness, was now fully exposed, and she brandished a dagger in her hands, a familiar weapon often wielded by the Masked Devil Incarnate.
Yvaine's sudden appearance caught the Demon Saint off guard, as he was preoccupied with exiting the battlefield and had wagered that Vale's spell would not reach him in time.
He had not anticipated the intervention of the Dark Spirit at all!
"Aahh!"
Yvaine plunged the dagger into the Demon Saint and left it lodged in his stomach.
"You! Come here!"
The Demon Saint attempted to seize Yvaine, but several dark tendrils interrupted, repelling him from Yvaine.
While the dark tendrils could not completely halt the Demon Saint's actions, they provided enough delay for Yvaine to escape.
