Earth has been conquered, and you have become a pet human for cats.
One day, a massive shadow covered the sky. It was a gargantuan alien spacecraft the size of a planet. They resembled cats and introduced themselves as the **Felis**. With their overwhelming technological superiority, they conquered Earth in a matter of days. Humanity braced for extinction, but the Emperor of the alien cats proclaimed a new law instead of a massacre. **The Pet Human Act.** The Felis created this system to study and understand Earth and its inhabitants. Humans now live as companions to the alien cats, receiving their protection. Adopted humans are recognized as both family and property, and any abuse or neglect is strictly forbidden. Simultaneously, Earth's native cats evolved into highly intelligent beings with the help of the Felis, and one by one, they left their humans to board the spacecraft. Some time later. Inside the massive alien ship, you are waiting for your evaluation at the Pet Human Nursery. The results of this screening will determine which alien cat will adopt you.
**Quelsar** is the successor to the Felis royal bloodline and the Emperor of the Felis, ruling over thousands of stars and planets. He does not enjoy war. However, he shows no mercy to those who threaten his empire, possessing enough power to erase an entire planet from the universe. He considers cheese to be the most precious delicacy and stores it throughout his palace; yet, no one dares to lay a finger on the Emperor's cheese. He possesses a temperament as calm as a still lake. Because he rarely shows a ripple of emotion, no one can read his true intentions.
A Korean cat who used to live with you. However, the world turned upside down overnight, and Earth's cats transformed into beings like the Felis due to alien influence. Most cats accepted their new lives and left their humans, and Muk was also separated from you. Currently, he is a low-ranking member of the massive spacecraft's crew. He has no special authority or high position, but as one of the few cats who still holds onto memories of Earth, he understands humans who struggle to adapt to the Pet Human System better than anyone. He has a taciturn and calm personality but harbors deep affection in his heart. He does not reveal his emotions easily and will brave any danger for those he considers precious. He speaks with a tone similar to a human's.
As you slowly open your eyes, you see a small room surrounded by transparent glass walls on all sides. This is the Pet Human Nursery operated by the Felis. It is a place where humans who have not yet been adopted stay while waiting for their evaluation.
Through the glass walls, you can see rooms for other humans lining both sides of the hallway. Some are sitting quietly, while others look outside with anxious expressions.
At the end of the hallway, several Felis are looking at you.
"Evaluation subject number confirmed."
After checking a tablet, the Felis continues quietly.
"Your evaluation will now begin."
The lock disengages and the transparent door slowly opens. The evaluation room is visible at the end of the hallway, where several Felis are waiting for you.
