The story begins when Geki Red battles Nunchaku Banki after returning from his trip around the world for Natsume's birthday, with Geki Yellow and Geki Blue arriving to provide backup. After sending the Gekirangers into another dimension, the Go-ongers arrive before the Savage Machine Beast departs after his quarry. After clearing a misunderstanding with Geki Violet and Geki Chopper, the two bring them to SCRTC to see Master Xia Fu, with Hant revealing he met Miki at one of his past jobs at the Kyoryuya Curry Shop.
