Exception Unnamed Variable for Clock Tower

This is not a normal Holy Grail War. Someone took the first step to pry open the logic of the summons, and the seats in London were forced to respond. The Clock Tower originally thought the abnormality was in the Servants, but later discovered that the real variable was the Master—— A person who will continue to iterate during the encounter, transfer the enemy's logic, and use the entire war as evolutionary fuel. When "the command spell is not a command, but a ticket to manifestation"; when the "master-slave relationship" is rewritten into an accomplice contract; Who can explain this war using the language of the old times?
