With Lala struggling to repair her rocket, Hikaru takes her to the local observatory, where a man named Ryo studies the stars, in the hopes of taking her mind off of things. As Lala remains defiant, Ryo shows her his planetarium, teaching her about constellations and relationships. Just then, another Notraider commander named Eyeone uses the power of a Dark Pen to turn Ryo's imagination into an evil monster known as a Notrigger. Realizing the meaning of Ryo's words, Lala relies on the help of the other Cures to retrieve the Dark Pen and convert it into the Leo Star Color Pen, allowing her to defeat the Notrigger, save Ryo, and revive the Leo Star Princess. Afterwards, Lala asks for everyone's help in repairing her rocket.
