Shadow Imitation Shuriken Technique

Shikamaru invented this technique while teaching himself to use Asuma Sarutobi's trench knives. By infusing the blades with his own chakra beforehand, they are given the effect of his shadow techniques. By using these weapons to pierce the enemies' shadows, they are paralyzed in place. To pierce the shadow, it is necessary to avoid the target just barely. As it is more difficult for the enemy notice it, this ninjutsu also compensates for the weak point of the similar Shadow Imitation Technique, being its limited effective range.
