Please define some limits to how many chidori senbon can be created with this jutsu, or just define a shape and area that the senbon would strike in. For example, they could land as a circle of senbon, or be shot out in a cone, or line with a certain width, etc. I would also ask that you remove the extraneous information involving Saskue and the nine tails chakra, as well as the Sharingan, as they are effects from other sources, and not a part of this jutsu on its own.
