Go! Princess Precure

Haruka was shocked to hear that Kanata thinks she shouldn't become a princess and shuts herself away from everyone; at that same time, Close has made it so the town of Yumegahama is about to be swallowed by a forest of evil thorns.

Haruka and Minami try to get in touch with Kirara Amanogawa, a first-grade student at Noble Academy who is a popular fashion model, in order to search for the lost Princess Perfume.

Kirara refuses to join the Pretty Cures even though she has transformed into Cure Twinkle; Haruka, who wants Kirara to join the Pretty Cures, goes to where Kirara works as a model after school.

The Noble Party, a formal dinner party in which everyone will participate in full dress, is coming up soon; Haruka challenges herself to make a party dress for the event; Haruka takes a lesson with the Princess Lesson Pad.

The Noble Party Haruka has been waiting for finally starts; the lights in the hall suddenly go out; Minami, the student council president, heads to the warehouse where the switchboard is to find out why.

The Dress-Up Key is said to be in a place filled with dreams at the Noble Academy; Haruka thinks that the school's dormitory mother Shirogane might know something.
