As Gai noticed how Luka is treating Ahim like a little sister, Captain Marvelous arrives as Navi's Treasure Navigate hints that the Gokaigers must help others to meet someone. With Gai unable to decipher which Sentai team the fortune relates to, the Gokai Galleon crew resolve to help people out at the nearest town. As Captain Marvelous, with Gai's support, copes with helping old people up the steps and Joe and Doc deal with a transvestite after they give back a ring that he dropped on the sidewalk, Luka and Ahim are in a park where they meet a pregnant woman and her daughter Miku. Then, all of a sudden, the woman goes into labor, but an EMT arrives to get her to the hospital via taxi. By then, Gormin arrive as the girls assume their Gokaiger forms to hold them off using the power of their color-respective Fiveman and Magiranger Keys. Soon after, Luka and Ahim visit the woman at the hospital, where she tells them that the delivery will be soon while learning that the EMT is actually Matsuri Tatsumi of the GoGoFive. After reporting to their crewmates, the girls arrive as Matsuri is attacked by Gormin while she is getting an injured boy into the ambulance. Covering her, the girls are attacked by Rio, Mere and Zubaan. Basco appears and reveals the Gormin attacks are his doing so he can get the GoGoFive team's Great Power. Realizing that she was the target on the prior attack on the taxi, Matsuri offers herself to ensure the boy's safe passage, but is pushed back into the ambulance by Luka and Ahim. Motivated by the memory of her younger sister Lia, Luka tells Matsuri that making sure the boy gets medical attention in time should be her only concern as she intends to cover their escape. But Ahim refuses to let her do this and suggests a different plan where she uses Magi Pink's Maagi Magiiro spell to assume Matsuri's form and trick Basco into letting the real one go. Though the plan succeeds, the two are unable to contend with the three extra warriors. Luckily, the other Gokaigers arrive in time and take out the Gormin with Gokai Silver battling Zubaan while the others assume the forms of the GoGoFive to overpower the Rinj?ken users. After the three Sentai warriors are defeated, with Sally taking the Ranger Keys back, Basco unleashes Fireroid Meran to deal with the Gokaigers as he takes his leave. When Magi Gokaioh's fire attack only makes Meran stronger, the Gokaigers use the GoGoFive Keys' Great Power to cool the Fireroid down before weakening him with Gokai Prominence so Goujyujin can destroy the monster. Luka and Ahim return to the hospital to see that the boy has recovered from his injuries while the woman has successfully given birth to a baby girl. Luka points out that Ahim is one step closer to becoming a real pirate while Gai notices that the girls' sisterly roles have reversed.
