"He must have lost his mind if he's prowling after Saber like that, thinking that she is Joan of Arc. This guy is useful. We don't even need to drive him away, just set our nets and wait."

"Master, that is not enough."

That was the cold, objecting voice of Saber, who had thus far been secluded from the discussion.

"With Caster's personality, if we do nothing and simply watch over him, then the number of innocent victims will only increase. His misdeeds are unacceptable. We should force him out before the damage spreads."

Perhaps Saber hoped that, with her sincere words, she could pass through the wall surrounding Kiritsugu's heart; if so, then it was futile.

As ever, Kiritsugu, with no indication that he even heard Saber's voice, spoke again.

"It'll be fine, Iri. We found no openings in the boundary field, and the alarm and scanning systems have already been checked..."

Biting her lip, Saber's expression became grimmer as she stared as Kiritsugu. While Saber could forcibly endure the way Kiritsugu ignored her, the righteous indignation that he would let Caster do as he wish was too much.
