"Not quite a wall." Suzaku smiled at him and moved a little distance into a space. "So the borderline you have been shown is stationary. Like this. Line."

He can cast it wordlessly now but he says it, to show the proper method. A borderline springs up a little distance away. A solid barrier of energy. After a moment Suzaku lets it fade.

"The attack uses the same movement and word, but you throw the energy at someone. Line!" This time a sharp blue line, smaller than the borderline flies into the air in front of him, moving some distance and then shattering.
