Miyuki was on Team Momotaros during the TimeWarp/Den-O crossover. Under the control of the pink Precure Mind, which was possessed by Momotaros at the time, and joined by her fellow lead cures, she challenged Eiji Higashi for his right to be called Precure. He won by a slight margin, using Cure Bright's power to defend himself against their finisher. Despite his victory, they told him that he was not worthy and sent him back wearing a banner that said "Japan's #1 Jerk".
Eventually, they gave him his Den-Buckle, allowing him to use his own version of Sword Form.
