The Miserable Life of a Cat Demon, Please Save Me

I am a cat demon with nine lives. I was originally a house-guarding mythical beast. I lived a comfortable life every day. But some god set new rules and asked us to take the system to the human world to experience it. Damn it, why don't you just stay patient? What the hell, I am the first unlucky person to come to the world without reluctance. Where is my magic? Where is my magic weapon? I'm going crazy if I'm left with this broken system and I'm still asked to do tasks.
