Seiji, controlled by Red's crystal, attacks the Cures, who attempt to break the crystal only to find themselves pushed back and overwhelmed by his power. After explaining that his crystal only allowed Seiji to embrace the hatred he now bares towards Megumi for her failure to realize his feelings for her, Red uses his power to send a large red planet crashing towards Earth while legions of Red Saiarks spread across the world before he and Seiji take their leave. Just as Megumi feels helpless, blaming herself for not understanding Seiji's feelings, Maria arrives just in time to protect her from a Saiark, reminding the Cures not to give up so easily and instead use their desire to save those they care about to gain new strength. With the other Cures from around the world giving them encouragement, the HappinessCharge Cures stand up once more to beat the Saiark before setting off to the red planet to confront Red and rescue Seiji.
The ruler of the evil Phantom Empire, Queen Mirage, begins her invasion on Earth using an army of Choiarks and powerful monsters called Saiarks. All across the world, Pretty Cures are dispatched to fight against the Phantom Empire threat. Hime Shirayuki, a princess from the Blue Sky Kingdom, which was taken over by the Phantom Empire, joins the fight as a Pretty Cure named Cure Princess, but always finds herself running away scared. Given a Crystal of Love by the Spirit of Earth, Blue, and told to seek out a partner to fight alongside her, Hime goes to the city of Pikarigaoka and randomly throw the crystal in the air, deciding to partner up with whoever it lands upon. This person turns out to be Megumi Aino, a kind-hearted girl always looking to help others, who is recruited by Hime to fight by her side as Cure Lovely.
