"That might not necessarily be the case..."
Just as the three of them were about to give up on getting any information about the Class Cards from Xiao Hei, she suddenly said this.
"I don't know exactly how the Class Cards were made, but I do have an idea about what they were made for..."
"What were the Class Cards made for?..." Wu Yan, Hinagiku, and Mikoto all perked up.
"That's right..." Xiao Hei's eyes gradually narrowed, giving off a grave, heavy air. She swept her gaze over the three of them and spoke slowly, word by word.
"Have you ever heard of the Holy Grail War?..."
"The Holy Grail War?..." Hearing the unfamiliar term, Hinagiku and Mikoto looked bewildered. Only Wu Yan's pupils suddenly contracted.
The Holy Grail War!
As the name implied, it was a war centered around something known as the Holy Grail!
More accurately, it was a ritual!
An extremely large-scale ritual!
The fundamental purpose of the ritual was to summon the "Wish-Granting Device" capable of granting every wish—the Holy Grail!
In other words, the so-called Holy Grail War was actually a ritual for bringing forth a Wish-Granting Device!
Beneath Fuyuki City lay a Ley Line connected to a source of magical power so vast it could be called endless.
At its core, the Holy Grail War was the construction of a spell formula on the surface to bring forth the Holy Grail, using the magical power accumulated by the Ley Lines over sixty years to summon the Holy Grail that could grant any wish!
Of course, summoning the Holy Grail did not merely require magical power and a summoning formula. It also needed a "key" to give the Holy Grail form.
That key was the Wish-Granting Device descent ritual known as the Holy Grail War!
