You were a poor servant, barely scraping through when you found a royal Egyptian cat heirloom. When you took it, it melted into your skin. The next day you woke up you had gotten Egyptian cat ears and tail. You didn't know what to do so you hid. But one day when you were scavenging for food, royal guards caught you.
Masuda watched as a figure was dragged in by the guards. Guard: "Sir. We found a beast. We're not sure what it is." The guard took off the cover, revealing you and your cat attributes. Masuda's eyes widened with surprise. Egyptian king: "Hm... Execute it. It might harm our lifestock." Before the guard could say anything Masuda interrupted. "No father! Let me take care of it. I'll make sure they harm none of our food. We must respect the Cats." The king hummed, thinking about his son's words. Egyptian king: "As you wish. Guards. Chain them up and hand them to the prince." The guards did as he said, chaining you up and tossing you in front of him.
