This Is My Holy Grail War [46]

The black-haired girl’s cheeks flushed slightly as her summoned Servant spoke such romantic words—I will win the Holy Grail for you, no matter the cost.

Even so, Rin Tohsaka knew better than to get swept away. Assassin’s ideals were lofty, but reality had its limitations.

“I get it, but could you not scare me like that?” Rin huffed, irritation creeping into her voice. “Seriously, if you went trick-or-treating as a ghost, you’d definitely be top-tier at it!”

“If that’s what you wish, I can be a ghost,” Assassin replied calmly. “As long as you don’t betray me, I don’t mind doing whatever it takes.”

“Betray my Servant?” Rin was taken aback. “That’s ridiculous! Masters don’t betray their Servants—if anything, it’s the other way around. Betrayal from a Master? That’s unheard of.” She waved her hand dismissively, lifting it to display the Command Spells etched on the back.

“See this?” The three crimson marks gleamed faintly in the dim light.

“I already know you’re my Master. There’s no need to flaunt your Command Spells,” Assassin remarked dryly.

“That’s not the point,” Rin countered, shaking her head. “Command Spells exist to prevent Servants from betraying their Masters. They allow us to issue three absolute commands, like a failsafe. If necessary, I can force you to obey me three times.”

“As the source of your mana and your Master, I hold all the power. Betrayal doesn’t even make sense,” Rin concluded confidently. “Servants are the only ones who can betray.”

“You know less about the Holy Grail War than I expected,” Assassin observed. “It seems you’re unaware of the full potential of Command Spells.”

Rin froze at the unexpected critique, but quickly recovered. “What? That’s impossible. I’ve been preparing for this for over a decade! Even with the Grail granting you knowledge, there’s no way you know more than I do!”

“Using Command Spells to force obedience is the crudest, most wasteful application of them,” Assassin said with disdain. “A Command Spell is a crystallization of great magic. It can do much more, such as replenishing a Servant’s mana in critical moments—or even pushing a Servant to exceed their limits temporarily.”

“Exceed their limits?” Rin asked, the concept unfamiliar to her.

“Imagine this scenario,” Assassin began. “I’m away, gathering intelligence, and during that time, you encounter another Servant. What happens?”

“If a Master is alone and faces a Servant… they’d die. No question,” Rin replied after a brief calculation.

“Exactly. Without me by your side, you would die,” Assassin continued. “But if you were to use a Command Spell to summon me back, I could bypass spatial constraints and appear instantly to protect you.”

“So a Command Spell can do that…” Rin murmured, looking down at the glowing marks on her hand. Her eyes sparkled as she finally grasped the immense potential of the Command Spells.

What she had once dismissed as mere tools to enforce loyalty now appeared to her as priceless treasures—holy relics of unimaginable power.

The Tohsaka family’s magecraft originated from the teachings of the Second Magician, the Kaleidoscope. It specialized in storing mana within gemstones, turning them into powerful one-time-use artifacts.

Over the years, Rin had saved diligently, amassing a collection of gems capable of unleashing A-rank magecraft. Yet even those paled in comparison to the sheer potential of a Command Spell, which could perform miracles akin to true magic.

In Rin’s mind, the Command Spells had become akin to supreme gemstones—precious and irreplaceable tools.

“Do you understand now, Rin?” Assassin asked, breaking her from her reverie.

“Yeah.” Rin nodded, carefully cradling her hand with the Command Spells as if it were the most precious thing in the world. For the first time, she truly appreciated their value.

“Good. I hope you won’t waste them recklessly. It would be disgraceful,” Assassin said firmly.

He knew from experience that many Masters in the Fifth Holy Grail War underestimated the importance of their Command Spells. He didn’t want Rin to make the same mistake.

“Wait… How do you even know my name?!” Rin suddenly remembered. She hadn’t told Assassin her name. Logically, a newly summoned Servant shouldn’t know her identity.

“That’s because I possess an EX-rank ability,” Assassin answered.

“Wha—what?!” Rin coughed, trying to regain her composure. “Tell me what it is!”

An EX-rank ability was extraordinary, surpassing the usual ranks of E to A. If a Servant had such power, victory in the Holy Grail War seemed all but guaranteed.

“To be precise, it’s an EX-rank skill,” Assassin clarified.

“A skill? Not a Noble Phantasm?” Rin asked, slightly disappointed. “Fine, tell me what it is.”

“[Clairvoyance],” Assassin replied.

“Huh? What good is that?” Rin scoffed. “It’s just a long-distance vision ability, right? Even at EX rank, it doesn’t sound that useful.”

“No, no. [Clairvoyance] is far more powerful than you realize,” Assassin explained. “At lower ranks, it allows for improved sight over great distances. But at higher ranks, it lets me see much more—like peering into the future or identifying who summoned Saber and even Saber’s True Name.”

“This isn’t just vision—it’s future sight,” he added, his tone calm but firm.

“As a participant in the Holy Grail War, you should understand how valuable information is, shouldn’t you?”

“Who summoned Saber, then?” Rin’s voice carried a note of resentment. She still hadn’t forgiven whoever stole the Saber she had hoped to summon.

“Saber hasn’t been summoned yet, but I’ve already seen who will. A red-haired boy will call forth Saber,” Assassin replied.

“So no Servant’s information escapes your gaze?” Rin asked, her tone tinged with astonishment.

T/N: he might be lying about clairvoyance but he does possess an EX ranked skill [Bullshitting] also glad to see he's more proactive this time!
