After noticing that the other Black Faction Servants were moving to surround him, Ulquiorra immediately retreated.
After all, he also possessed the ability of "Shared Vision," so it was not difficult for him to detect the Black Faction's movements.
As for how running away so decisively might hurt his dignity—sorry, Ulquiorra truly did not care about that. To borrow Shirou's words: "Dignity? How much does that cost? Could you sell me two pounds of it?"
In any case, Shirou's goal had only been to prevent Siegfried from digging out his heart to save someone. Since that goal had already been achieved, nothing else mattered.
Besides, compared to Ulquiorra, Sieg was the one in trouble. When Astolfo had taken him fleeing earlier, they had run around like headless flies, with no destination whatsoever.
"Ah, we should be fine now that we've run this far, right?" Astolfo stretched her body and spoke as though a burden had been lifted. "Come to think of it, we really owe that strange guy this time. After all, I'm no match for Saber."
"Rider... do you know that mysterious person?" Sieg was rather puzzled. That shouldn't be possible. Astolfo and Ulquiorra are completely from different settings—how could they possibly know each other?
"Hehe, of course... I don't!" The cross-dressing beauty grinned and said something that left Sieg covered in black lines.
I was foolish, truly foolish. How could Astolfo possibly have crossed paths with someone from the Soul Reaper setting during her lifetime?
Just as Sieg sank into Xianglin Sao-like muttering, Astolfo's next words yanked him straight back to reality:
"Eh, come to think of it, where are we?"
At that instant, Sieg felt the string called reason inside him snap. He staggered and stared at Astolfo in disbelief. "Rider... don't tell me you're lost now."
