Upon seeing the young man in the black trench coat appear with a black revolver in hand, Qonas Kilgor, who was no stranger to all the important figures in the world, immediately responded.
The thumb on his left hand that held the iron-skinned pocket watch was rapidly moving, reaching for one of the metal buttons on the messy inlays of the pocket watch. He suddenly raised his right arm, aiming at Gehrman Sparrow with the six gray gun barrels that formed a circle.
This process was like a fleeting spark that quickly came to an end. As for Qonas Kilgor's left thumb, it had pressed down.
He overcame his instinct and didn't directly use Restriction from the Concerto of Light and Shadow.
This was because he didn't know Gehrman Sparrow well enough, unsure as to what he was best at. Furthermore, the person with Gehrman Sparrow's appearance might not be Gehrman Sparrow. Blindly using Restriction would only be a waste of an opportunity.
