With Stinger and Champ looking for Scorpio and Kotaro temporarily absent for training, the other Kyurangers' next mission is to rescue the people imprisoned at the Space Dragon Palace Castle. Garu, who is upset because he has not been chosen for deployment lately, has his wish granted when the Kyulette selects him to join the Palace's infiltration team.

Searching for the Perseus Kyutama, Lucky and his friends encounter Mardakko once again, and discover, much to their surprise, that Doctor Anton is still alive.

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.

The Kyurangers face a new enemy that restricts birthday celebrations, and Lucky uses a unique Kyutama to call for some special help.

To obtain the last Kyutama needed to break Don Armage's barrier, the Kyurangers set for the Cassiopeia System, where the local Karo challenges them for a baseball match.

The Kyurangers track down the location of the Ho Kyutama, one of the components of Argo, on Planet Vela, whose people are suffering with the pollution caused by Jark Matter. Meanwhile, Stinger finally comes face to face with his brother.

After liberating Lucky's home planet, the Kyurangers split into two groups again, looking for the means to break into Planet Southern Cross to confront Don Armage, but Shou is starting to feel left out, as Tsurugi has been a better leader than him.

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.

Despite having a glimpse of Don Armage's whereabouts, the Kyurangers have no way to go after him now that they lost the Orion, until Eris appears again, with news of another ship hidden on Earth, and upon finding it, they meet Shou Ronpo again.

The Kyurangers are reunited again and they set out for the Crux System to confront Don Armage. On the way there, they decide to infiltrate a competition held by Hoshi Minato, known as the greatest artist in the universe, to learn about his possible connection with Jark Matter.

The Kyurangers have no clue about Don Armage's whereabouts since their last battle, until they hear of planets exploding mysteriously in the Corvus System and set course there, unaware that Tsurugi is keeping a secret from the others.

Now with the team complete, the Kyurangers decide to start their campaign to liberate the universe with Earth. Lucky obtains the Pegasus Kyutama that grants him a special armor. However, he fails to control it and the team takes part in a rather unusual training routine to help him master it as they encounter the powerful Ikargen and Mardakko.

The Kyurangers have obtained a new spaceship and Shou returned, but they have no clue of what happened to Champ. Just when Kukuruga attacks the Kyurangers with an android resembling him, a mysterious warrior appears to help them.

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.

The Kyurangers return to Earth to stop Don Armage's plan to destroy the universe, but as Tsurugi's condition worsens, Doctor Anton stands in their way. Anton transform into his monster form and enchant citizen to attack Kyurangers

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.

After reclaiming the Tomo Kyutama, the Kyurangers must wait for the Rashinban Kyutama to recharge in order to look for the next piece of the Argo and take their time continuing with their campaign against Jark Matter's forces on Earth. However, their next enemy is Scorpio, the Karo of the Scorpius System and Stinger's older brother, who uses his poison to transform his victims into zombies.

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.

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!

The Orion, the Kyurangers spaceship, heads towards Earth. There’s always one Daikaan on every planet, but there are multiple Daikaan confirmed to be on board the Moraimarz on Earth. Lucky and the others head down to investigate, where the Daikaan known as Yumepakkun steals and eats the dreams of children. Meanwhile, Raptor 238 dreams of fighting together with the Kyurangers, and her wild ideas and fascinations with fighting are only getting bigger.

Stinger accompanies Champ who was heavily damaged while protecting him from Scorpio for repairs. Meanwhile, the others have a hard time against a new enemy that can't be seen, until Lucky obtains a new, powerful Kyutama to fight back.

The Kyurangers set out to look for the Ryukotsu Kyutama on Planet Keel, but Scorpio steals it and they must fight him for its possession.

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

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