The Grey Vulture Knight's current condition is not normal, and Count Shuren has also noticed this. However, Kudler, the People's Guard, having already assured as a "senior" figure in the line of Grail Knights, that a "bewitched" state like the present is quite normal.
When he became the Nantes Ranger after drinking the water from the Holy Grail, he was also bewitched for several months before he returned to normal.
According to Kudler, this is a necessary stage after being "touched by the divine artifact and granted the power of the oath," and he knows of several historical Grail Knights who have had similar experiences.
He does not see this as a problem.
Because the power that guides the spirit to "ponder" the world and the nature of the oath does not leave any sequelae, the current situation of the Valande Knight evidently strikes "professionals" differently.
