Prunce deduces that the noise from the Star Color Pendant is related to the Star Princesses. As Hikaru tries to find where the noise leads to, she ends up butting heads with Lala, who wants to wait until her data analysis is complete. After receiving some advice from Elena Amamiya, a florist who is popular at Hikaru's school, Hikaru and Lala learn to stop arguing and listen to each other properly. Upon figuring out that the pendant is acting as a radar, the girls find a Star Color Pen, but it is swiped by another Notraider commander, Tenjou. With Tenjou defending herself with her Notray troops, Hikaru relies on Lala's help to get her through Tenjou's defenses and recover the Taurus Princess Star Color Pen. Using the pen's power, Fuwa revives the Taurus Star Princess, who urges the girls to help Fuwa grow and retrieve the other pens in order to save the universe. In the end, Hikaru and Lala apologize for their bad behavior and are forgiven.
When Hikaru Hoshina transforms into Cure Star, she embarks on an outer space adventure to find the rest of the Star Twinkle Cures and save the universe!
