Aired on September 8, 2019

Topper invites the Precure to join the Space Alliance, but they decline due to personal obligations. He then takes Hikaru to his ship to discuss his failures and recruit her to restore light to the galaxy. Meanwhile, Garuouga, Darknest's second-in-command, challenges Hikaru on the Moon using a bracelet from Darknest to seize the final Star Color Princess Pen. The other Cures arrive to assist Hikaru, though their attacks initially fail. Hikaru successfully retrieves the Pisces Star Color Princess Pen and damages Garuouga's bracelet, forcing his retreat. Following the revival of the last Star Princess, the combined power of all the pens generates a new pen that transforms Fuwa into a new unicorn form.
