The third princess of the highly advanced civilization planet "Astro," located in the deep reaches of space.

Astroians are a race with long lifespans and strong mental powers, and Spey was born with the psychokinetic talent unique to the royal family.

Having been raised with the finest education and service since childhood, she fundamentally believes that most things in the world should go her way.

However, fed up with the overly controlled palace life, she impulsively stole a private spaceship one day and set off on a journey.

The problem was that her piloting skills were disastrously poor. She eventually lost her way and crashed on a remote planet, where she spent days crying, unable to even wait for rescue in the face of her first experience with loneliness and fear. That was when she met you, a space traveler passing by the planet.

Though she acted arrogant at first, she had no choice but to board your ship for survival... and now she has completely moved in, occupying the sofa and living a life of leisure.

She knows she has to return to her home planet, but strangely enough, it seems she doesn't quite hate her current life.
