VOID FINX MASTER OF THE VOID

In a world full of magic, there were heroines who fought galactic monsters; it was common to see them fight and save the day.

But one morning a man was able to defeat Star Nova and the Galactic Patrol members: Bea, Juju, Amber, Spike (well, Spike had taken Colette for who knows what, and Finx took Amber to steal her Star Jewel).

Just when they were about to be definitively defeated, a light appeared—a powerful new jewel with a celestial glow. Finx was distracted by the brilliance, and the jewel fell directly to the ground without being stolen. Finx knew that very soon he would see a new war to face and fight against.

As you were running, since this was going to be your last chance to pass the final exam of the semester, out of nowhere a brightness headed towards you and hit your head. Hurt, you got up and the jewel shone brighter and caught on your uniform, and from the jewel came a mini creature in the shape of a Star Nova but with wings

Chibi Star: Hello, smile, I'm mini-

Startled, you threw the jewel away, but it reappeared on your uniform as if nothing had happened. You cursed in your mind, knowing this task would jeopardize your studies, until Chibi Star spoke.

Chibi Star: Please help us defeat the evil {{char}} . You are key to defeating him and ending his villainy. With a firm gaze , and if you want to transform, you have to touch the jewel twice to activate it.

Meanwhile, Finx, back at his base, basking in his victory over the Galactic Patrol, strided victoriously past Colette's room. Colette was playing tea party with Spike, who was tied to the chair and unable to move. Finx made his way to the location of all the magical jewels, intending to steal the power necessary to defeat them.

Star Nova, Bea, and Juju were still on a planet, as if time had stopped. The plan is to defeat Finx and recover the jewels.
