Shadow Sewing Technique

Within the arcane repertoire of the enigmatic Nara clan lies an esoteric ninjutsu, a closely guarded secret technique that transcends the mere bounds of their Shadow Imitation prowess. This cryptic artistry harnesses the very substance of manifested shadows, not for mere immobilization and control, but for a visceral onslaught and ensnarement. The adept practitioner undergoes a metamorphic transformation, transmuting their own shadow into a myriad of razor-sharp tendrils, each pulsating with an autonomous sentience. These shadowy appendages, under the wielder's precise dominion, commence a symphony of simultaneous assaults, laying siege to a single or multiple adversaries. Simultaneously, they insidiously pilfer the target's locomotion, constricting them in an inextricable web of shadowed filaments.

The artifice, while devastating, entails an inexorable physicality, rendering the capture of a quarry an inevitably injurious affair. Nonetheless, this arcane virtuosity compensates with celerity and unflagging persistence. In moments of dire exigency, this technique emerges as an indispensable instrument of immediate restraint.

Typically employed to penetrate and ensnare an opponent, its utilization may diversify, transmuting into an offensive gambit to vanquish the adversary as dictated by the exigencies of the confrontation. However, its foremost utility unfurls when deployed as logistical support, underlining its unique distinction. Upon contact with the quarry, this technique retains the capacity for seamless transition back into the venerable Shadow Imitation Technique. Conversely, once the prey succumbs to the immobilizing clutches of the latter, a skilled practitioner can adroitly segue into the Shadow Sewing Technique, thereby inflicting dire reprisal upon the ensnared party.

Trivia

 * This ninjutsu takes its name from the "Kagenui", a technique from ninja legends that immobilises a target by pinning their shadow with a kunai.
 * In Naruto Shippūden: Ultimate Ninja 5, Shikamaru throws several explosive tags up in the air and uses this technique to pin them on his opponent.
 * In Naruto Shippūden the Movie: The Will of Fire, Shikamaru uses the special seal used in the Multi-Size Technique instead of the Bird seal, as the ring and little fingers were raised in the manga, but the index finger is raised instead of the ring finger in the movie. The folded fingers are also interlocked in the manga, but not in the movie.
