It's a simple mirage technique used as a counter. It's mostly a Rain technique, but has a small Mist trait. What the move does is creates an illusionary clone of the user that upon being struck, will lash at the attacker and suspend and completely stop their movement for a short moment, as well as eating away all of their momentum, meaning if they were in the air and were struck by this, would simply drop to the ground. The mist aspect is that the user turns invisible for the duration of the clone.

I had other mist techniques planned, but this counter-type one is kind of core to his style. It's a defensive/punish fighting style that uses trickery as one of it's factors.
