Season 1

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!

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.

With eight members in their team, the Kyurangers confront Eriedrone and Stinger. Lucky once again asks Stinger to join their cause. Divided between his faith and his feelings, Stinger makes the final decision.

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

Shou sends the Kyurangers to wipe out five enemy outposts at once. Meanwhile, Spada decides to help the population's suffering with his cooking. But when Ikargen and Mardakko appear, Shou himself intervenes just in time to everyone's surprise.

Spada is captured by Ikargen and Mardakko, and Shou, having finally perfected his transformation into a Kyuranger, joins the others to rescue him.

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.

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.

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.

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.

Stinger and Champ are eager to settle their scores with Scorpio, but he approaches Stinger instead and tells him that he is working inside Jark Matter to kill Don Armage instead. Stinger agrees to listen to him, unaware of his true intentions.

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.

Mardakko steals the Rashinban Kyutama, that is necessary to find the final piece of Argo and the Kyurangers give chase, encountering Space Sheriff Gavan Type-G and the Dekarangers along the way.

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.

Stinger returns to Earth to confront Scorpio alone but ends up controlled by his poison. Kotaro also returns and joins the other Kyurangers to help him.

The Kyurangers have their decisive battle against Scorpio, and finally assemble the three Argo Kyutamas, gaining a new and powerful ally.

After being brought back to life, Tsurugi Ootori declares that the other Kyurangers had accomplished their duty and must leave the rest to him. However, Lucky and the others refuse to comply.

Tsurugi hijacks a Jark Matter station to declare to the whole universe that he will defeat Don Armage once more. However, when he ends up risking civilians' lives, Lucky loses his patience towards him.

With several Kyurangers captured by Jark Matter, Lucky and Tsurugi must settle their differences and work together to rescue them. Tsurugi reminiscene about his old comrade, Quervo.

Now with the 12 member team working together, the Kyurangers set to Planet Toki to reclaim a new Kyutama that allows them to travel through time. Once arriving there, Kotaro has an unexpected encounter with his mother.

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.

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.

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.

Lucky finds a wrecked Orion in the present and sets for the past to discover what happened to Tsurugi and the others.

Lucky and co. at last discover the truth about Don Armage, and Lucky, armed with a new Kyutama that bestows him the power of Orion, confronts him head on.

Despite Don Armage was apparently destroyed in the past, the present has not changed at all, and the Kyurangers confront Akyanba to release Naga from her control.

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 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.

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.

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.

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.

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.

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.

With the power of the Andromeda, Cassiopeia, Cepheus and Perseus Kyutamas, the Kyurangers break into Planet Southern Cross chasing after Don Armage, where they encounter a mysterious masked assailant.

The mysterious warrior serving Jark Matter is no other than King Aslan, who is possessed by Don Armage. This fact shakes Lucky's conviction, until his friends decide to give him a piece of mind.

While Lucky confronts his father and Tsurugi faces Don Armage himself, the other Kyurangers rush to Planet Southern Cross' core to stop Don Armage's bomb, which is powerful enough to destroy the entire universe.

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.

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

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.
