|This article is about a/an episode in Kaizoku Sentai Gokaiger.|
Gai shows his finalized Super Sentai Encyclopedia for his crewmates to research how the previous Sentai teams fought. Joe, who shows no interest, leaves the Gokai Galleon to pick up food - with Gai following him to learn more about him. During their walk, they bump into a young boy, who nearly hits Gai with his bicycle. The boy, named Shota, arrives at a nearby shrine to wish for fair weather- only to see Action Commander Stargul holding a black stone. Spotted, Shota and pedals away from the Zangyack and his Gormin, running into Joe and Gai who assume their Gokaiger forms quickly dispatch the Gormin. Despite Gokai Blue turning into AbareBlue to his ally's dismay, he and Gokai Silver as DragonRanger overwhelm Stargul before he falls back upon remembering his mission.
After the fight, though they notice his wound, Shota tells Gai and Joe that he is fulfilling a promise he made with his friend Daigo to watch the shooting stars on Kamikura Mountain. Though Joe reminds the boy of another idiot (getting Marvelous to sneeze back on the Galleon), he mends Shota's wounded leg and telling him to go to his destination. Returning to the Gokai Galleon, Doc obtains information about the black stone, revealed to be the Reiseki Warabe-ishi that when joined to its other half grants its user limitless energy. Joe realizes that the location of other stone is at Kamikura Mountain, where Shota is headed. Fearing for Shota's safety, Joe and Gai head for the mountain, while the other Gokaigers follow suit as Stargul combines the two stones.
Fighting a group of Gormin that are keeping intruders away from the submit, Joe and Gai save Shota. Though Gai tries to talk him into leaving, Shota refuses while revealing the full story behind his promise with Daigo as Joe allows the boy to pass to Gai's dismay. By the time they reach the mountain top, the Gokai Galleon crew find that Stargul has absorbed the stones' energy and uses his Meteor Dive ability to summon an asteroid toward Earth. Transforming to negate his ability with his destruction, the Gokaigers use the powers of the Goseigers, Dairangers and Ohrangers to overwhelm the Action Commander's power boost.
However, refusing to give the Gokaigers the chance to destroy him, Warz Giru impatiently fires the enlarging beam. Forming GokaiOh to save Shota from Stargul, with Gokai Blue encouraging the boy to continue, the Gokaigers form Shinken GokaiOh with GoZyuJin supporting them in destroying the Action Commander. However, in his dying breath, Stargul reveals they are too late to stop the asteroid's course to Earth.
When GokaiOh's Gokai Star Burst has no effect, Gokai Silver has Gokai Blue use GokaiOh to throw GoZyuJin in the air at the astroid, enabling the latter robot to destroy the asteroid with the Gokai Dengeki Drill Spin. By sunset, Shota manages to fulfill his promise with with Daigo as they watch the shooting stars with the Gokai Galleon crew looking on. Though Gai compares his actions to the previous Sentai, Joe states that Shota did all the work in fulfilling his dream.
