Seiza Sentai Kiseiger

Hyperus18 imagines Star Twinkle PreCure but it's Uchu Sentai Kyuranger.

Plot
I'm Hikaru Hoshina! But yet I ain't Hikaru Hoshina! (Yeah, I am not the one from Star Twinkle PreCure, that is!)

I'm a 19-year-old who loves space and constellations!

While observing the starry sky to draw a constellation in my notepad, a mysterious creature known as "Comet" warped before my eyes!

And then, a rocket fell from the sky, which had pretty much most of the Kyurangers come with it!

...You guys, are actually aliens!? YOSHA LUCKY-

Each system has a Kyutama, and there are 88 of them that represent the 88 modern constellations.

If this situation continues, the stars will disappear, meaning Earth and the whole universe will be swallowed by darkness...!

"When the star's light are lost, the legendary Kyurangers will rise together to make them shine again."

Rika says she is searching for the Kyurangers along with Comet in hope that the legend will make the universe go back to how it was before.

But then a Notraider who wishes to control the universe appeared and attacked Comet...

When I thought "I want to save Comet!", my strong emotions created a "Seiza Blaster" and summoned the "Shishi Kyutama" which, transformed me into Shishi Red!?

Now I have to collect the scattered Kyutama and have Comet grow up.

Alright, let's leave Earth and jump into space...!

 * It's very similar to my STPC adaptation PRaAK.
