"How much longer until you reach us?!"
The situation was urgent; even Kirei Kotomine's voice carried a hint of urgency.
"Huh? We're already heading there as fast as we can—"
Holding her phone, Rin Tohsaka glanced out the car window and replied to Kirei Kotomine.
Anno was driving, with Shirou Emiya in the front passenger seat. In the back sat the two Matou siblings, Rin, and Illya. The six of them were crammed into a van speeding toward Ryuudou Mountain.
Rider Xiang An, relying on his own speed, had already headed there ahead of them with his Master, Hinako Akuta. The remaining six were traveling by van.
The three Servants—Adelson Falgao, Archer Emiya, and Berserker Heracles—were following behind in spirit form.
"If something's happened—Xiang An is already on his way to you. He should be there in a few minutes!"
"I see. Understood—just get here as quickly as you can."
"The black mud... has already started overflowing."
Just two short sentences, yet the sense of urgency they conveyed was immense.
"Black mud..."
Illya clenched her hands, gritting her teeth.
"We'll get there as soon as possible!"
Shirou Emiya leaned over and spoke to Kirei Kotomine, his face filled with killing intent.
The call ended, and Rin Tohsaka sighed.
What the hell was this mess?
But this time, they had to keep the scope of the disaster as small as possible!
"Heh... hehehehehehahahahahaha—"
Justeaze's feet had touched solid ground within the Great Cavern. Her lips curled upward as she let out a strange-sounding laugh.
"Who exactly are you?!"
Kirei Kotomine lowered his body, keeping himself where the black mud could not reach him, and sternly questioned the so-called "Justeaze."
—That was definitely not the real Justeaze.
Both Kirei Kotomine and Bazett knew that.
