Pixl is the main female protagonist in the game who fell into Planet Starpoint and is unknown of what the entire place is or what purpose is. 

Pixl is not mostly the one of not knowing much about how she got into this world unwillingly, but is wondering what this planet has to offer, as she’s just a different little girl that was known for any new adventures, mostly happy and cheerful, (but can get angry easily if you test her badly) and is ready for anything that comes in her way!

Teida is the second protagonist in the game along with Pixl as an unlockable character after Pixl's run of the Story Mode and was a tag along with Pixl or as a second option besides Pixl in the Character Selection.

Teida’s run through Starpoint is when Pixl fell into this world in sync when Teida was around the village when Pixl was trying to figure out the planet, and from her perspective, is that she was not as adventurous and not much as Pixl, but is happy to be open to be in one as she tags along with Pixl without noticing that she was tagging along.

Rexel is the main antagonist in this world and in the game, and the story of this villain is drastic from how it starts when Rexel is off for Pixl for her when she knocked into to him during his starting schemes that would want to make the world into a planet full of dread and dead, but with his plans changed to take down Pixl and the planet.

Rexel is a dimension hopper, hopping through many dimensions to find any type of artifact, gem, stone, emerald that held maximum power or energy that can be used to power his bases and enemies until he finds the main place for his operations. Planet Starpoint.
