Seiza Sentai Kiseiger

Seiza Sentai Kiseiger (星座戦隊キセイジャー) is the first season of Hyperus18's PreCure but it's Super Sentai/Kamen Rider.

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 Seiza Key, 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 Kiseigers will rise together to make them shine again."

Fang says he is searching for the Kiseigers 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 "SeizaKishi Changer" and summoned the "Shishi Key" which, transformed me into Shishi Red!?

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

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