I'm Hoshina Hikaru, a second-year middle school student who loves constellations and space! Today, when I was looking up at the starry skies, I drew my own original constellation in my notebook. But then my picture shines, and out comes a strange fairy called "Fuwa"! At last! I've always dreamt of meeting someone from space!! The next day, as I searched for Fuwa who had left my room, I bumped into aliens called Lala and Prunce. Glitterific~ ☆ However, it seems a bad alien has targeted Fuwa...

What, the rocket is broken!? But the alien Lala can fix it herself! Not only can she drive the rocket, but she can do so much more too, which sounds amazing!! She's only a natural because she's an adult. Wait, she's 13 too!? That's the same age as me!! I wonder if Lala would want to be a Pretty Cure too...? Don't worry, I'm sure Lala can transform as well!

Huh, I heard a sound come from my Star Color Pendant! But then just as I heard it, it stopped. So Lala decides to examine the pendant overnight...And apparently Prunce can tell us exactly where the Princess' power lies! Glitterific~☆ Alright! Time to get searching~☆ But Lala wants me to wait until she has completed her analysis of the pendant...! What~ Maybe you should analyse it as we search~~! Gosh! I'm not waiting anymore! I'll find it my way!

Shines as bright as the sun! Amamiya Elena is a popular girl who is incredible at sports! Together with Lala, I went to the flower shop "Sonrisa"! It just so happens to be Elena's family house too~! Sonrisa means "to smile" in Spanish! Elena's siblings are all smiles and get along really well. Now I can see why she's called the sun: she's surrounded by smiles! But on the way back from Sonrisa, a Nottoraider appears before us...

Kaguya Madoka is the "Moon" of the school as well as the student council president! She's smart, can play the piano and is amazing at archery too! As Hikaru, Elena and Lala looked after Fuwa, Madoka came from out of nowhere and found out about Fuwa! Madoka's father investigates aliens so now she wanted to talk to the girls about Fuwa. Problem is, since Lala and Prunce are aliens, if Madoka were to reveal their secret, they wouldn't be able to stay on Earth anymore!!

Lala is trying her hardest to fix the rocket but ends up failing to do so each time. Hikaru decides to take her, along with Elena and Madoka, to the observatory to help her relax and have a bit of fun. There she introduces them to Ryoutarou, who tells her that the stars' lights are beginning to weaken.

The girls set out to repair the rocket together. Hikaru got stuck with cleaning up, which she finds boring, so she draws a picture in the Twinkle Book to convey her wish of flying in the rocket. With the others feeling the same way, the rocket is fixed...but then a Notraider appears.

The girls finally go to space, in which they follow the Star Color Pendant to Planet Kennel. There they meet the aliens Doggie, Maggie and Neggie who look like dogs but talk a lot like humans. At the temple, they find a Princess Star Color Pen but the dogs refuse to hand it over.

Hikaru finds out that Madoka has never tried Star Donuts before nor has she ever gone to the shopping district. This is because Madoka spends her days studying, practising her archery, performing tea ceremonies and flower arranging. So to take some of the stress off Madoka's shoulders, Hikaru decides to take her, with Lala tagging along, to the shopping district and have Madoka try Star Donuts for the first time...

"I want to see the southern cross constellation" is Hikaru's desire so she and the others go back into outer space. And before they knew it, the Star Color Pendant reacts and they are teleported to Planet Coumarin...
