Inchato gives his clansmate an approving nod. "Quite good." Inchato turned and strode over to the part of the needle between Kuzan and the boulder. "Because of how thin it is, the needle remains quite brittle, even though it does require a good deal of chakra to make." Without warning, Inchato slams his elbow, supported by his other arm, into the needle, shattering it in half. "Because of this, blunt forces of a b-rank power and above can shatter it if they hit it from the side."
"One more thing: this jutsu is nigh impossible for a non-doujutsu user to see when its dark outside. If a light source isn't shining directly on the needle, it's not going to be possible for someone to see it coming, so long as you point it at their eyes." And with that, Inchato dissolved into snowflakes, which blew away into the wind.
