Uaio created this technique during a confrontation with a shinobi. He creates a Silhouette of his opponent which stands and looks like a person but that is completely black with no features. It is essentially a clone, and can act on its own jutsu like one. It can use its body to perform other Shadow Related abilities such as Shadow Sewing Technique. It can also use other types of Ninjutsu that the user can, and the user can hide ninjutsu within it as well using the Hiding Within Shadows Technique. The shadow stays conneted to the enemy no matter where they are or how fast they move unless they use kamui. A big advantage is that it is still a shadow and cannot be hit by any means since most attack will just go through it, although this is also a disadvantage since it is a shadow distorting
