An ordinary detective on Earth, let's call him "the detective", encounters an unprecedented case.
It requires him to... become the pet of Daigneux, an enigmatic and beautiful alien girl!
This blonde girl may look sweet and pretty, but she's got a savage streak underneath, and has no respect for any lifeforms. She even has the ability to summon an army of powerful monsters!
Daigneux, who has a long criminal record for destroying several planets, is the infamous Celestial Tyrant!
Under her tyranny, how will the protagonist use his wisdom to survive?
As a pet, the only way for him to improve his standing is to... conquer planets?!
His job duties: serve Daigneux, exercise, and command monsters!
As a weak, pitiful, and helpless Earthling who can't do anything but eat, the only rule he needs to survive on this alien planet is...
Leech off Daigneux as much as possible!
