Shadow Imitation Technique

The Shadow Imitation Technique is a signature technique of the Nara Clan which allows the user to manipulate their shadow.

Usage
The user extends their shadow on any surface (even water) and as far as they want as long as there is a sufficient area. Once it comes into contact with a target's shadow, the two merge and the target is forced to imitate the user's movements. Therefore, the two can throw shuriken at each other at the same time if the user desires that (of course, to prevent hurting themselves, the user just has to have the shuriken holster in a place where you don't normally have it, like the back, so that the opponent draws nothing when the user draws a shuriken). If the target is out of range, the user can produce a better light source to increase their shadow's size or rely on pre-existing shadows for their shadow to freely travel through. It's also possible to split one's shadow, either to trap more opponents at once, or to create a distraction.

Drawbacks
The major downside of the Shadow Imitation is that it is tiring to use repeatedly; Hidan notes that the ability is subject to some form of diminishing return and decreases in potency after repeated use (Shikamaru Nara can only maintain it for 5 minutes per use). If the user is low on chakra, the performance rate of the technique also deteriorates. Insufficient lighting will make the technique less effective. A particularly strong opponent can also resist the shadow's forced imitation. The technique also forces the user to move the same as the victim so if the victim was hit with enough blunt force to move them, the user has the movements forced on them.
