Flying Wild Dance is Asuka and Homura's Secret Fusion Ninja Art in Senran Kagura 2: Deep Crimson. It requires at least 3 ninja art scrolls from both of them to use. Like all Secret Fusion Ninja Arts, its power increases with the characters' mutual Affection.
Both Asuka and Homura take a stance before they both charge towards their enemies. From there, the two unleash a barrage of slashes while simultaneously crossing one another in the process. The two then slash down before finishing the move off with a swift uppercut of the their blades and a friendly back-to-back pose.
