Per-formation
As I'm taught the basic description from Nathan sensei I inherit the knowledge what he teaches me, a then stand out, stretching my legs and shifting them wide apart from each other, and take out some shurikans from my backpack, and attach five of them with a string, and then to my fingers, throwing them to towards your clone, as they rush at fast speeds to your clone, the clone evades them by moving strafing, to the left, I then tilt and form movements from my fingers altering their initial trajectory, changing their Orginal course and shifting them to the left in the direct postion the clone moved, the shurikans move and strike your clone, two of them hit your clone one above the shoulder, the second shukrikan piercing the left leg.
How to use it in battle
Well, the ability to alter the shurikans movement is pretty skillful and a handy method of hitting the opponent accurately, the most thinkable method for this, I can throw the shukrikan towards my opponent, the enemy might assume since they're shurikans they will travel straight forwards and will strafe, either to the left or right, if he does that I can shift their course, immediately surprising him and hitting him, which is great to catch him off guard during that point since he might've have thought he evaded them but in actuality, they're coming straight for him. The shurikan method itself is pretty good to cause the enemy to loose focus on concentration, since most jutsus require concentration and focus to remain intact and usable.
