Box Formation

Shinan has his insects attack an opponent in four separate swarms, each swarm is sped up using Shinan's chakra. From there the swarms fly at the target, attacking in curved assaults before passing the target by. The swarms attack separately from each other, keeping up a consistent rotation in order to stop the enemy from retaliating. The technique gains its name for the fact that the swarms only travel a certain distance away from the target before moving in to attack again, usually changing direction very suddenly giving onlookers the illusion of the target and bugs being trapped within an invisible box.
