Rin curled her lip and muttered under her breath, "You make it sound so easy. Do you think Holy Relics are free? They're expensive, okay?!"
"Shouldn't your family have Holy Relics left over from the previous wars? Wouldn't it be fine to use one of those?"
Rin: ...Could I say there weren't any?
Suddenly, a spark of realization flashed through Rin's mind. Her eyes widened, and her pupils trembled violently.
"No, wait... Th-that broken catalyst, could it have been... the Holy Relic Father left me?!"
"I don't know what it was, but most likely."
"Ah! I screwed up again..."
Rin clutched her head in regret. Though she had no idea which hero the Holy Relic was connected to, Rin trusted her father and firmly believed that it had been tied to a powerful Heroic Spirit who suited her perfectly!
"I even reminded you beforehand not to mess things up. Honestly~"
Seeing Shinji spread his hands with an expression of either regret or schadenfreude, Rin's anger flared at once. "That still makes me better than you! You disgraceful descendant of Makiri! And don't underestimate me. Even if something went wrong with my Heroic Spirit summoning, I'll still win in the end!"
"Say whatever you want~" Shinji shrugged, completely unfazed by Rin's mockery. "And even if your magecraft aptitude is indeed pretty good, are you sure you and your Servant can handle Saber? As far as I know, the Three Knight Classes have high Magic Resistance, and Saber, the strongest of them, is especially outstanding in that regard. I don't know what kind of magecraft the Tohsaka family uses, but it probably won't have much effect on Saber."
"Saber is the strongest..."
Shirou looked with some surprise at the composed Saber beside him. Saber straightened herself slightly as well, apparently quite pleased
