While Lucky, Hammie, Garu, Balance and Kotaro stay in the present to rescue Naga from Akyanba's influence, the others travel to the past to discover Don Armage's secret, where they must deal with a group of trespassers aboard the Orion.

Naga's back on the team and the information he got when he was under Akyanba's control may lead them to Don Armage. However, the Kyurangers also discover, much to their grief, that the Orion is damaged beyond repair, just when Kukuruga, the third of the Fuku Shoguns makes his move.
