Harajuku, a place where culture, fashion, and cuteness gather.High school girls Rito, Mari, and Kotoko run a pop-up shop called "PARK" in the neighborhood. One day aliens come to Earth and begin stealing humanity's culture. Then a mysterious girl calling herself Misa appears. In order to defend their beloved Harajuku, the three girls take action.

Using the Amatsumara, the device they received from Misa that turns anything you imagine into physical objects, the girls fight off the aliens known as Scoopers. By enveloping the entire neighborhood of Harajuku in a bubble, Rito, Mari, and Kotoko are able to defend the city. Misa and her pet Ebifurya offer their help, and together they begin searching the bubble. However, that's when the Scoopers return...

Rito and friends learn there are other survivors inside the bubble besides themselves. One of the survivors, Sayumi, is handing out hand made crepes to the people of Harajuku in order to make them smile. Inspired by Sayumi, the trio begins preparing to re-open PARK. However, when Rito finds herself unable to draw, she goes to look at a drawing she previously made on a city wall...

Kotoko's acting strange. Actually, she always acts strange... But she didn't pull out people's hair or lurk about with syringes before. Rito and Mari find her behavior suspicious, but Kotoko refuses to explain herself because she's afraid of being alone again and accidentally tears Rito's drawing. Then a Scooper appears...
