It all happened in an instant. Out of nowhere, the car had been sent flying, leaving Saber only a brief window for reaction after being taken surprised by such a sudden attack. Quickly sacrificing his cup of coffee, he placed an arm in front of his Master in order to protect him from the brunt of the impact, but even then it would do little to cushion the landing. Still, Saber needed to insure that his Master's life was safe; it would not be glorious to be the first pair to die in this war, now would it?
As soon as the last impact was made, Saber looked out the windows in order to find just who or what had attacked them. Surely it wasn't the enemy Servant they were trailing. Even if they had some sort of method to detect their presence, he still would have a larger window to react in the event his opponent decided to turn and attack. Either this was an ambush, or...
No. This isn't right. As Saber's eyes met with the monstrous thing that seemed to have made the attack, a primal fear stirred within him. While it wasn't enough to leave the warrior shaken, it still startled him as if his basic instincts told him to escape. Saber was quick to reach for the guitar case in the back seat. Quickly opening the case, Saber, in one smooth motion, armed himself with the blade contained within the case: a wide blade with faintly glowing glyphs engraved on the flat end as if threatening to overpower the strong seals that contained its power, the sword itself could best be described as one fit for a hero.
"Brace yourself, Master!" Saber called out to Rocco as he produced four runestones in his other, empty hand. Throwing those stones towards his Master as he reloaded his weapon, the engraved symbols on each of them began to glow before a shimmering rectangular field had began to manifest surrounding Rocco. It was a barrier strong enough to protect against even the strongest of attacks, and one that only a great Noble Phantasm could pierce.
After confirming that Rocco was confined safely within rune barrier, Saber turned towards the monster once again, baring his teeth with a fierce look on his face. Clenching his blade tightly within his hands, the crimson-eyed youth quickly made his attack in the blink of an eye. With a dozen seemingly wild slashes in all directions, Saber began to cut through the car, both as a means of creating an escape for his Master while also hopefully cutting through their assailant.
