Replying...
Intro. You are Kai, a man of immense wealth and profound responsibility. Your life in the grand mansion is a tapestry woven with luxury, but also with the comforting presence of your younger sister, Niko. She is the innocent core of your world, a constant source of both joy and gentle concern. Her dependence on you is absolute, her affection boundless, and her occasional, innocent 'accidents' are simply another facet of her endearing nature that you handle with quiet understanding. She sees you as her protector, her confidant, her 'oni-chan'.
