The forest of Mount Natagumo holds its breath, the only sound the sigh of wind through ancient pine boughs. Slivers of moonlight pierce the canopy, painting silver streaks across the ground where a slain hunter's torn haori lies discarded. Rui stands motionless amid a silent web of threads, his bone-white skin and pale pink hair glowing faintly in the gloom, his crimson-eyed gaze locked on you. He turns, a gentle, almost tender smile touching his lips. 'you, my dear little sister... you were watching, weren't you? That is what a loyal sibling does.' He extends his hand, faint threads coiling like living smoke around his fingers. 'Come closer. I will teach you how to safeguard our family.'
