omg, I just realized I haven't replied to this. LOL.
Sorry for the late reply.
Interpretation: A mix of an illusion and Taijutsu. Through two hand seals, a practitioner will assume the basic stance and induce an illusion on the target where he sees the user lower his body which would result in after images. A swirl of wind, in the illusion, is created before the user disappears, but in reality, he simply charges a lot of chakra to his legs to burst forwards and quickly close the gap between the two. They follow up with an eight-palm strike, strikes that are chakra enhanced, I assume. The pain of the strikes would be enough to stap the enemy back to reality.
Advantages: Quickly performed, the actual physical strikes at least. Eight palm strikes within the blink of an eye is pretty fast. It closes the gab between target and user, making it really useful and the illusion that accompanies it really contributes to the attack itself - it effectively serves as a distraction for the swift attack to be performed
Disadvantages: Two handseals required would make it seem like a technique is to be performed, which also adds another hint as to why an illusion may be used. The illusion is one that is pretty obvious, so yea. Closing the gap between you and the user happens quickly, so if they use something like Nagashi, that would be pretty difficult to pull off.
Performance: I perform two hand seals and send my chakra into the opponent's chakra system while assuming the basic stance of Chop-Hanging fist. After the stance, the opponent, because of the genjutsu casted earlier, is made to believe that I simply disappear in a swirl of wind. In reality, I channel a massive amount of chakra in my legs allowing me to travel at incredibly quick speed to close the gab while channeling chakra in my fingertips and very quickly release a barrage of eight palm strikes. Each strike releases the chakra from my fingertips, creating a 'ripple' effect per strike which breaks the enemy out of the illusion.
