Star☆Twinkle Precure

A girl named Hikaru encounters three aliens—Lala, Prunce, and Fuwa—while observing the night sky. They tell her about the Star Palace, a place once protected by 12 Star Princesses who maintained cosmic balance before being attacked. Lala seeks the legendary Precure warriors to recover the 12 scattered Princess Star Color Pens and restore the princesses. After Fuwa is captured, Hikaru expresses a desire to rescue him, prompting the appearance of a Star Color Pendent and Pen, enabling her transformation into Cure Star. She then joins the effort to gather the pens and aid Fuwa, who plays a crucial role in reviving the princesses.
