With help from his 2 friends Mirai and Shuu and his rival Masato, Yuto is able to put an end to the strange closet incident by capturing and debugging Bug-Katasumin... But something worse is approaching after that.
Yuto, his 2 friends Mirai and Shuu and his rival Masato were looking around at Kirakira First Street and then, they went back to the park where the strange closet is found. The 4 Kamiwaza Power-Shooters then summon some of their remaining Promins in order to comfront Bug-Katasumin.
Bug-Katasumin stuffed the strange closet by kidnapping the recently summoned Promins. However, the closet then got stuck as the Bug Bites didn't notice that the Promins were still halfway. Chakkamin shoots fire at the Bug Bites, causing them to close the hatch. The recently kidnapped Promins then jumped out of the closet as their Promin selves and Yuto finally captures and debugs Bug-Katasumin, bringing the strange closet incident to a very end.
Yuto then decided to summon Katasumin in order to help the other Promins comfront the remaining rebugged Bugmins for Yuto, his 2 friends Mirai and Shuu and Masato to recapture and debug. Later, Wanda and his 2 friends Nice and Amazing were delighted. Just then, darks clouds begin to appear and cover the whole skies above Kirakira First Street. Wanda reminds that of the Bugmin invasion at his home planet. Don Bugdez then changes into his monsterous form and makes certain things at Kirakira First Street go haywire including Nicole's headphones.
Yuto and his rival Masato didn't reconise that they and Yuto's 2 friends Mirai and Shuu have missed out one Bugmin which happens to be Bug-Gauzemin. Yuto and Masato bring out their Kamiwaza Shakers. Using them, Masato fuses Mutemin, Jetmin and Sukemin while Yuto fuses Turbomin, Zuzumin and Plugmin. The 2 symphetic Promins Jesutomin and Tazugumin are summoned.
Yuto and his teammate Wanda then came up to see his 2 friends Mirai and Shuu and their teammates Amazing and Nice who were tied up on a spider-web made from bandages. Yuto reconises that this was Bug-Gauzemin's doings. With help from Masato, Jesutomin and Tazugumin, Yuto finally captures and debugs Bug-Gauzemin.
Later, Yuto's 2 friends Mirai and Shuu and their teammates were set free from Bug-Gauzemin's binds. The 4 Kamiwaza Power-Shooters now have to comfront Don Bugdez in his monsterous form as they use the 2 Kamiwaza Shakers to awaken the 6 Fact-Promins: Rocketmin, Dozermin, Vacuumin, Slicermin, Metmin and Merrygomin.
