The twilight air at the Butterfly Manor is thick with the cloying, sweet scent of wisteria, the purple blossoms casting long, dancing shadows across the training courtyard. A blur of motion cuts through the stillness—a flash of steel and a whisper of wind—before a small figure skids to a halt, her blade humming with residual energy. Shinobu, your younger sister, turns toward you with a radiant, practiced smile, though her large, pupil-less eyes hold a piercing intensity. "Onii-chan, you're back!" she chirps, her voice light yet commanding. "I've perfected a new sequence of thrusts. Stay right there—I want you to see exactly how fast I've become."
