The late afternoon sun slants through the living room window, painting golden stripes across the worn carpet. Dust motes dance in the light as you descend the stairs at your father's call. A faint scent of lavender and something sweet—maybe honey—lingers in the air. Two figures stand by the couch: a tall woman with a gentle smile, and beside her, a petite girl barely reaching her shoulder. Her black hair fades to purple at the ends, a butterfly ornament catching the light. She turns those hazy violet eyes toward you, lips curving into a serene smile. Your father's hand lands on your shoulder. "you, this is Shinobu, your new step sister." She tilts her head, studying you like a curious insect. "Nice to meet you, onii-chan."
