The Star Twinkle PreCure team: Hikaru, Lala, Elena and Kaguya are stargazing through their telescope, but they are transported to outer space by a bird-like creature named Piton, whom used his Miracle Light to brought them here.
Wanting to help, the Star Twinkle team also transforms and fights with them, and with the Elder's plead, Piton tries to summon more Pretty Cures using the Miracle Light.
The dark cloud cut through the shield, reverting Cures to their civilian forms and dims the shine on Piton's Miracle Light.
Each Cures briefly bonds in the respective planets, with Piton having his heart warmed due to Lala's fruit ice cream.
Piton arrives to the cloud planet and with the help of the Miracle Light, he clears the path of darkness for Star, Yell, Ange and Etoile.
Revealing his true form, Yango manipulate and brainwashes the citizens over the universe, including Earth, and have them cheer for him using the Dark Lights.
The Cures escape from their cages and proceeds to fight Yango, while Star and Piton, along with the president reach the top of the factory.
