Yuto tells his parents and his sister Yui that he and his friends are going on space journey to the Wonder-Star. Yuto summons Zuzumin in order to keep Yui and her new friend Mako, who were doing their favourite hobbies, entertained. Nice and Amazing wanted to go on a space journey too. Then, according to what Yuto says, his mother and his father both agree. That delights Yuto and his 2 friends Mirai and Shuu and their 3 Kamiwaza teammates.
Later, Yuto and his friends are at a space station. Tora Imauma and some of the Promins were working very hard, constructing Wanda's spaceship, while Zuzumin and Momotaru cheer for them. Soon, after Wanda's spaceship was completed, Yuto, his 2 friends Mirai and Shuu and their 3 teammates got into their astronaut suits, ready for their space journey to the Wonder-Star, and all the rest of the Kirakira First Street citizens, including Masato, Mako, Nicole, Souma and Yui, and anyone else that Yuto and Wanda have met so far are wishing them good luck. Terara, Megaga and Gigaga were also watching. The 3 kids and their Kamiwaza teammates all got into Wanda's spaceship. Rocketmin then takes Wanda's spaceship up into the sky, taking Yuto, Mirai and Shuu and their teammates with them.
Inside Wanda's spaceship, on their way to the Wonder-Star through space, Yuto and his 2 friends and their 3 teammates were chatting to each other encounter Don Bugdez. They try to think of a way to get rid of Don Bugdez for good. Then, Mighty came with his Kamiwaza Pod which was destroyed by Don Bugdez. Mighty gave Yuto the 2 Kamiwaza Shakers, giving Yuto and his 2 friends the chance to summon the 6 Fact-Promins with the Kamiwaza Shakers. Yuto fused Turbomin, Jetmin and Tafumin throughout his Kamiwaza Shaker and uses his Kamiwaza Power-Shot to summon the tri-symphetic Promin Tajebomin.
Tajebomin then rescues Mighty. Yuto and his 2 friends command the 6 Fact-Promins to unleash a full 6-way blast at Don Bugdez. Being hit by the blast, Don Bugdez couldn't keep up much further on. At last, as he disappears for the final time, Don Bugdez was gone for good. Yuto and his 2 friends and their teammates have won the battle.
Meanwhile on Earth, Terara, Megaga and Gigaga decided to go away after Don Bugdez's extinction. As they were about to leave, the 3 ended up turning back into their toy selves all of a sudden.
Back inside Wanda's spaceship, Mighty thanks Yuto for saving him with the tri-symphetic Promin Tajebomin which has now defused back into Turbomin, Jetmin and Tafumin. Yuto and his 2 friends, their teammates and Mighty all arrive at the frozen Wonder-Star. As the got there, they use the 2 Kamiwaza Shakers to summon the secret Promin Wonder-Promin.
As he was summoned, Wonder-Promin then unleashes his powers to unfreeze the Wonder-Star. At last, the Wonder-Star, as well as the Wonder-King, was thawed and Don Bugdez's curse was removed. All the other Wonster-Star citizens came, cheering for Yuto, Wanda, Mirai, Amazing, Shuu, Nice and Mighty. Delighted, Wanda reunites with his father the Wonder-King. Then, the Wonder-King and all of the other dog-like citizens of the Wonder-Star thanked Yuto and his 2 friends Mirai and Shuu for freeing their planet from Don Bugdez's evil spell. The Wonder-King decided to let Wanda stay as his heir to the throne. Yuto, Mirai and Shuu were surprised. Wanda, his rival Mighty and his 2 friends Nice and Amazing said to Yuto and his 2 friends that they meet up with them again someday.
After leaving the newly-purified Wonder-Star, Yuto and his 2 friends Mirai and Shuu head back to Earth. Yuto then gave his sister Yui a box of chicken karage bites. However, Yui felt sad whilst thinking about Wanda. Yuto felt sad too as he was missing his teammate.
As because he was thinking about Yui, Wanda changed his mind, letting Mighty become the Wonder-King's heir instead, and decide to return to Earth and reunite with Yuto and his 2 friends Mirai and Shuu. Popping up and behind some of the crates, Wanda came back, with his Kamiwaza Searcher, to see Yuto. He said that there were still some Bugmins remaining on Earth. Yuto, his 2 friends Mirai and Shuu and Yuto's sister Yui all agree. The 3 Kamiwaza Power-Shooters, Yui and Wanda all leap into the air for a group photo, ending the episode in a cliffhanger.
Meanwhile, the Bug Bites, now in their toy forms, found themselves in a box in Yuto's bedroom, getting prepared to be sold in Hobby Kamiya.
