Defend! The last princess pen ☆

Catching up to the girls as they arrive back on Earth, Topper of the Space Alliance requests that the Precure join them, but the girls turn him down due to their personal obligations. Noticing Hikaru's Twinkle Book, Topper takes her to his ship to talk about his failings and ask her to join the alliance to help him bring light back to the galaxy. Just then, Darknest's second-in-command, Garuouga, appears to challenge Hikaru on the Moon using a bracelet given to him by Darknest. As Garuouga obtains the last Star Color Princess Pen, the other Cures come to Hikaru's aid. Although their attacks seemingly have no effect against Garuouga, Hikaru manages to retrieve the Pisces Star Color Princess Pen and weaken Garuouga's bracelet, forcing him to retreat. After the final Star Princess is revived, the power of all the pens brings forth a new pen that transforms Fuwa into a new unicorn form.
