He pulled up the right sleeve, checking the number of the Command Seals his father had managed. As expected, there was one less. Risei had given one of the Command Seals under his management to someone, and had presumably been murdered by this person soon after. One of the Masters that had won merit in the process of the crusade against Caster had been dissatisfied with sharing the credit with the others he had fought alongside, and had therefore committed such a crime. There was essentially no need for analysis to be able to determine the entire sequence of events.

But even a magus could not seize all the Command Seals from the hands of the dead elderly priest. The Command Seals managed by the supervisor were protected by holy prayers. Without his permission, it is not possible to seize them through the use of thaumaturgy. Father Risei, the only one who knew the secret holy words, was already dead; the Command Seals of previous Grail Wars preserved to this day could no longer be used.
