Shirou Kotomine was a priest despatched by the Church, and he also had the duty of being the overseer of this Great Holy Grail War. Therefore, he possessed the [spirit board] that was given to the overseer and could perfectly grasp the state of all fourteen Servants.

Incidentally, the Yggdmillennia camp had also obtained a [spirit board] through their connections. Thanks to the sub‐species Holy Grail Wars, there were abundant means to purchase one.

“I’ve confirmed that Saber has died with the [spirit board], but it seems his Line hasn’t been completely cut.”
