Rising Wing is a Dual Link used by Riku. While activated, Riku will be able to fly through the air and assault enemies with arching sweeps of his Keyblade. If Riku attacks after each jump then he'll be able to glide until the link gauges run out.
When using Rising Wing, Riku gains a bright blue aura around him. He gains small wings which enable him to glide.
