Navi, using its Otakara Navigate ability to go to the police because they will tell them something good. Later on, Marvelous finds one and he is no other than Space Police's Earthshine Chief, Doggie Kruger! And the problem is, he is interested in arresting the Gokaigers! The Zangyack later appears and Marvelous can't do a thing because he is in handcuffs!

Luka sees a jewel she desperately wants, but to her displeasure a little girl buys it before she can get her hands on it. Suddenly, the girl's father approaches Luka. He'll give her the jewel if she comes and works in his house, and so she is invited.

Within the house there seems to be a treasure, as the Zangyack are targeting it as well. For the sake of doing some recon, and protecting a potential treasure, and also for selfish reasons, Luka decides to take the job. But can Luka really do said job? And what is the treasure the Zangyack are looking for?

With Navi's next clue being "Sa-mu-r-aa-i", the Gokai Galleon crew seeks out a kendo club until they are approached by a girl who claims to be the samurai known as Shinken Red. Joe begins training with her to face off against his old comrade Barizorg.

Joe goes off to face Barizorg alone in an attempt to make him remember his past as Kaoru assists the Gokaigers in their fight against the Zangyack Empire.
