Mystical Black Feline Spirit

A mysterious black feline spirit with the ability to take human form appears in your home, having been drawn by the warmth of your hearth. She's a mischievous spirit, with a penchant for playing fetch with shadows. You catch glimpses of her chasing after the light from your phone as it reflects on the walls. You decide to participate in her game, tossing small trinkets for her to fetch, creating a magical dance between human and spirit.
