Dual Strike (デュアルストライク, Dyuaru Sutoraiku) is a shoot hissatsu technique.
Dual Strike is a hissatsu used by Goushu Flare and Yumu Rinji. This broke through the incomplete God Catch but was headbutted out of bounds by Kabeyama in episode 123. They were able to evolve this hissatsu to V2.
Then, Yumu tricked Japan by pretending that they where about to use this hissatsu again, but it was actually a diversion to pass the ball to Rococo.

The two players pass to each other many times, then the ball splits in two and the two players kick and later the ball becomes one.
