Ninpō: Thunder Stone (忍法 雷礫 Ninpō: Kaminari Tsubute?) is a ninja art used by Gabimaru.
Overview
Gabimaru first stomps on the ground to send the gravel beneath his feet in mid-air and throws a swift kick to launch the stones as projectiles to injure his opponent. Gabimaru uses this technique to attack from a distance in case he can not allow himself to get too close to his opponent.
