“I do believe Uncle is correct… ultimately, the Holy Grail is just a massive pool of energy. It certainly will be enough to grant most wishes. It is possible for it to bypass all theories and processes, and bring about only results. In the opposite manner, however, any wish it is capable of granting requires a process to omit.”
Coming to a realization, Sieg asked Jeanne.
“But then… isn’t it meaningless to wish for the salvation of humanity?”
“In such a case, yes. For example, if you simply asked the Holy Grail to ‘save mankind’, it would cease to function as long as the wisher did not possess some concrete idea of what procedures that would entail. A wish is a wish, it requires a set course to reach its conclusion.”
“And what if this Shirou does have a concrete idea? Regardless of whether it would truly lead to salvation?”
Jeanne swallowed her breath as Sieg hit the weak point in the logic.
“If so… then I believe the Holy Grail will carry it out.”
“But how could such a method exist?”
Caules shook his head at Fiore’s words.
“I don’t think that’s the problem here. The issue is, what if this Shirou believed strongly enough that his method was enough to save humanity?”
“But…”
Fiore tilted her head in confusion.
“Do you see, Master? The Holy Grail is not able to fulfill desires for which the wisher himself knew of no way of being carried out. In reverse, the Grail can act when the wisher does possess such a concept. The worry is that the ‘method’ chosen by him will be one that brings disaster upon mankind.”
Without some solid form of implementation, there would be no further concerns. However, provided Shirou Kotomine was in possession of such a thing – even if the majority of humanity would believe it to be mistaken – the Holy Grail would most likely activate.
“So that’s it, then? Let’s say there’s a man who wishes that he’s the best Magus in the entire world. In his mind, that meant every Magi better than him ought to be dead. Are you saying that the Holy Grail would go ahead and do it for him?”
