If You Take a Cat Girl as Your Sister, She Won't Become a Yandere, Right?

I dreamed that I picked up a wet cat lady on a cold rainy night. I dreamed that on the ruins of the end of civilization, a heart was put into a mechanical cavity. I dreamed that, as an exiled prince, I would fight for her against the insect tide in the entire universe. I dreamed that, as a god-killing warrior, I laughed at the fear of the entire world because of her. I dream, trillions of broken dreams, I participate, I change, I witness. Later they declared my name thus: The sleeping master in the purple mist dream; The creator immortal who holds the power of virtuality and reality; A traveler from all realms who transcends the boundaries of time and space; The immortal Tao body unified in three generations; The master of cause and effect; The purple source of all existence.
