Prologue: Fall of Nebulex Kingdom
In a castle, a maid is pulling a girl while running. Not long after, they enter a room and the maid immediately closes the door behind her. She then leans on the doors as she slides down onto the ground.
Maid "Miss, please hurry up and escape. We can no longer fight them!"
The girl shakes her head "No, I'm not leaving without Ginna!"
Maid grabs the girl's shoulder on both sides "Please, you know there is only one way save this kingdom. You must leave now, princess Seika!"
Seika takes a few steps back "I… But can I make it? If I fail, then…"
The maid suddenly feels she got hit by something and thinks "No way, when did I… Princess Sekai must leave now!"
She then looks at Seika with a warm smile "You will be fine. With your power, I'm sure you will be able to make it."
Seika notices the sudden change and grips her hands tight "I… I'll do my best. I'll definitely find help and save everyone!"
The maid smiles as she watches Seika envelopes in white light and disappears.
The maid then says "I wish you best of luck, Seika…"
She then closes her eyes and dark energy begins the cover her. After darkness subsides, she is wearing a stiff-looking suit.
She slowly stands back up while muttering "I am… right. I'm a Nebulex Negaminion, number 15213."
She looks at the place Seika teleports "Priority target is… princess Seika. Target's goal finding help."
She then takes out a tablet and looking through some data "Worst case scenario is… reaching the Precure in that idol world. I must report to Princess Ginna."
The Negaminion then walks away and leaves the room.
