Natsu was once more sent to the ground as someone ran into her and as the said person apologized she looked and she saw Griff, quickly regaining her balance echoing the fighting stance he had.

She may be fast, but he had an advantage. She looked at the structure of the building, his projection rate, and a solution came to mind. The air around her got surreptitiously colder, and she grabbed her sword and sliced the air twice cutting off a beam of wood, causing it to fall in front of Griff, a hint of frost on the wall.
