This is a ninjutsu using materialized shadows, but compared to the Shadow Sewing Technique from the same line, this technique places emphasis on the minute control of the shadow's movements. It is accurate enough to even make the tentacles go through tiny holes. Basically, this technique takes the user's own shadow and transforms and stretches it into countless thin tentacles, which are then used to grab objects and pull them in. Also, one can also skilfully make use of the tentacle-shaped shadow tendrils by using them to lift up and throw weapons like kunai and such. This technique has many possible applications and uses. There are no hand seals used for this technique, but the hand movements resemble that of Gaara's Sand Binding Coffin.
