After their latest win, the three Gekirangers find the Kensei stretching for their annual Kensei Great Athletic Meet. Jan, wanting to win the gold medal and a year's supply of Televi magazines, joins the Red Team to go against the White Team. With Retsu as judge and Ran as moderator, the contest starts...
While in the middle of fighting, the Gekirangers and Mere are teleported to Hong Kong, along with Rio and various other martial artists around the world. Just as Rio and Jyan were about to fight, they meet the mysterious Lao Fan before seeing others brought to the island as well.
Beast-Fist is a form of martial arts where the powers of a beast can be acquired by sensing the beast in their hearts. There are two relative schools of the Beast-Fist. One, the Beast-Fist of justice, Geki Juken Beast Arts. And one, the evil Beast-Fist of Rin Juken Akugata. The two schools of warriors learn and change in order to increase in power every day, as they are destined to clash.
