88 constellations that exist in the universe have fallen into the hands of the evil Space Shogunate Jark Matter. However, the insurrection army Rebellion and three Kyurangers chosen by the Kyutama are opposing them to protect the people. By an accident, an adventurer traveling through space, Lucky witnesses Chamaeleon Green, Oushi Black, and Kajiki Yellow fighting on the planet Cthros. Lucky decides to become the 4th Kyuranger and they set out to planet Jagujagu to search for the Kyutama.

The search is on for the remaining four Kyurangers. Lucky lands on Planet Jigama and encounters Balance and Nāga. They call themselves the “Phantom Thief Group BN”, stealing only from Jark Matter. Lucky hears their next aim is to steal a jewel from Jark Matter’s space ship Moraimarz. They soon meet the first Daikan commander, Gamettsui, who Balance betrayed. Elsewhere, Jark Matter’s general, Eridron, appears before Hammy and the others.

On the desert planet of Needle, a danger of explosion has been identified due to Jark Matter sucking up the planet’s energy. Lucky and the others go down to Planet Needle to deal with Jark Matter. Once there they happen upon a man named Stinger, who has a Kyutama!

As the other Kyurangers face a crisis when the Orion goes haywire, Lucky takes Kotaro back to Earth, but when they are attacked by the enemy, Big Bear's spirit appears to them, and after witnessing Kotaro's true determination to protect the world, grants him the power to fight as the 11th Kyuranger.

Shou informs the other Kyurangers of their next move, which is to assemble three special Kyutamas that together, unlock the power of the legendary spaceship "Argo", necessary to bring down Jark Matter. However, Lucky has an unusual string of bad luck and trying to prove himself despite that, he confronts Ikargen and the revived Mardakko alone.

After Ikargen steals the Tomo Kyutama from the Kyurangers, the team looks for a way to get past his mysterious ability to evade all their attacks. Shou comes with an idea to outsmart him, but Lucky is still shaken by his string of bad luck and stays behind, until he decides to bring up his courage and fight back.

The Kyurangers take a day off to have some barbecue, when Akyanba, one of the Fuku Shoguns, approaches Naga and transforms him into an evil servant of hers.

Balance finds Naga, determined to risk himself to bring his friend back to senses. Meanwhile, Tsurugi and his group arrive at the past, seeking to learn what actually happened after his final battle against Don Armage.

Still surprised with the recent revelations about Don Armage, the Kyurangers depart to answer a distress signal from Planet Luth, where Lucky was raised.

Lucky learns from his foster father that his father, King Aslan has joined Jark Matter, and sets for his birthplace, Planet Kaien to confirm it.

Still wary of Tsurugi's situation, the Kyurangers join together against Don Armage who is possessing Quervo's body.

Now possessing Tsurugi's body, Don Armage absorbs Shou and is stronger than ever. Having a plan to rescue both from Don Armage's grasp, the remaining Kyurangers prepare themselves for the final battle.

The Kyurangers are reunited once more and face Don Armage one last time to decide the fate of the universe.
