Rito, Mari, and Kotoko run a pop-up shop called "PARK" in Harajuku. Aliens come to Earth and begin stealing its culture. A girl calling herself Misa appears and helps the girls defend Harajuku from the invaders.

Rito's body transforms rapidly into a Scooper. Mari and Rito are relieved to see her obsessively eat candy, but she suddenly groans in pain. Rito begins running out of control. In a desperate attempt to stop her, Mari and Kotoko turn their weapons against her. Seeing the tears in her eyes, they think back on the days leading up to the opening of PARK.
