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.

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 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.

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.
