What it does:
This technique is a collaboration of Shadow Shuriken Technique with itself used by two coordinating shinobi. To initiate this technique, the first shinobi makes contact with the second who simultaneously signs the 'Dog' hand seal and transforms into a weapon in the first's inventory, typically a Giant Shuriken, though another weapon may be used if it measures at least 2 feet.

The first shinobi will then throw their weapon that was imitated by the second, as well as the imitator themself simultaneously such that the thrown shinobi is concealed in the shadow of the thrown weapon. The thrown shinobi and the weapon can independently change their direction at jutsu speed by no more than 90 degrees on either side of its original trajectory once per post, while remaining within 15/25/35 meters of each other. The weapon itself, and the thrown shinobi will each individually deal damage equal to jutsu power.

The transformed shinobi remains invisible to the naked eye but detectable to passive chakra sensory. If either of the users have the sensory specialty however, the transformed shinobi is better concealed and may not be detected by any means or chakra sensory except with the use of either chakra vision or a sensory technique with a greater power than 20/30/60 or jutsu power if both shinobi have the sensory specialty. Should the weapon be stopped, the concealed shinobi will still continue towards their target independently. As such, the two components of this technique behave as completely independent techniques until the concealed shinobi is detected by the target. Should the target identify the transformed shinobi, this technique becomes less effective and its parts cease to behave as independent techniques. The concealed shinobi will always cease to be invisible by default once they reach within 3 meters of their target.

Both the weapon and the concealed shinobi can pierce through other techniques (physical and chakra) with a lower power than this technique without taking damage. Notably, the concealed shinobi themself will also be invulnerable to debuffs while in their transformed state, and will have this jutsu receive debuffs for them instead. Any stat checks will also check jutsu power first.

The second shinobi behaves exactly as a regular weapon that they have imitated. They cannot imitate augmented ninja tools. They cannot form hand seals or use or maintain any other techniques until their transformation is undone. They can choose any point within its trajectory to undo their transformation voluntarily, or be forced out of transformation if successfully struck by a technique with a greater power than Shadow Shuriken Technique. If this were to happen to the weapon or the imitator, the damage from the opposing technique would be inflicted on them as normal. While transformed, the shinobi can wear and carry any equipment that they have on their person.
