Ada Jones is transmigrated into the interstellar era and joins the dangerous Starshine Sanatorium to survive. She unexpectedly awakens SS-class Primordial Guide mental power. With mental soothing, she heals and protects three powerful Sentinels, Test Subject 001 Mike Smith, Test Subject 007 Raven Rivera, and Test Subject 044 Gray Cooper, while exposing the sanatorium's true identity as the Abyss Research Institute, a secret live-subject gene extraction facility run by Prince Valen. She confronts Valen as he attempts to seize divine power and slaughter innocents. Ada upholds justice, unites her allies, destroys the lies, and uses her Primordial bloodline to end the war, protect the people across the stars, and ascend as Empress, ushering in a new era of equality and peace.
