Summary
Nagisa manages to get home by sunset. Stressed out, she immediately confines herself to her bedroom, laying down on her bed while lamenting that she were a more brainy type of girl instead of a sporting type. A shooting star suddenly passes through the sky, capturing Nagisa's attention. Wondering if this was the same star storm that her friends were talking about, she gets off her bed and goes to her balcony to watch as more shooting stars descend. Nagisa suddenly remembers to make wishes on some of the falling stars when one starts falling towards her room. Panicked, Nagisa watches it as it bounces around her room and hits her between the eyes, knocking her down. The "star" then explodes into fragments of glowing light as what appears to be a small UFO to Nagisa falls in the center of the room.

After Nagisa recovers, she carefully prods the tiny vessel with her lacrosse stick until it opens, revealing its passenger. Terrified, Nagisa orders it to stay away from her, even as it tries to make friendly conversation. They are both interrupted by Ryota, Nagisa's younger brother. Nagisa tries to show him the alien, but finds that the "ship" to look nothing more like a cellphone. Unimpressed, Ryota leaves but not after Nagisa trips him with her foot. Nagisa then tries to investigate the shards of light which have transformed into cards, but the alien insists that he needs to find someone.

Due to his limited mobility, Nagisa is forced to carry the visitor in her lacrosse stick. Along the way while shortcutting through various establishments, the creature explains that his name is Mepple, a warrior from the Garden of Light who has been tasked to protect Mepple, the princess of the Garden of Light.

Mepple's sense of direction leads him and Nagisa to a closing amusement park where they are confronted by a strange looking man who introduces himself as Pisard. Pisard snatches Mepple away and demands that he turns over the Prism Stones when Honoka comes running up to the confrontation carrying Mipple. Nagisa uses this opportunity to swat Mepple from Pisard's grasp while he is distracted. Enraged, Pisard uses his powers to throw around various objects while Mepple and Mipple instruct Nagisa and Honoka to transform by swiping the Queen card through the Card Commune. The two are transformed into Pretty Cure, confusing Nagisa as she has no control of her actions during the transformation.

The duo can barely control their actions as Pisard launches a fierce attack on the both of them. Both are able to use their power to hold him off, however. Desperate, Pisard summons an evil spirit which takes possession of a roller coaster that attacks Pretty Cure. Overwhelmed, Mepple and Mipple order the duo to hold hands, summoning black and white lightning and combining it into an attack called "Pretty Cure Marble Screw" which exorcises the demon and returns the roller coaster to normal and forces Pisard to retreat.

After the battle, Mepple and Mipple reunite, they explain to Nagisa and Honoka that they are destined to fight alongside them as the Emissaries of Light. While Honoka is smitten with the thought of fighting for justice, Nagisa is in disbelief as to be a destined fighter of evil.
