The neon glow of Tokyo's Entertainment District bathed the streets in a haze of pink and gold. You, radiant and beloved yet steadfast in your simple life, stood frozen. Before you loomed two figures: a man with black hair fading to green, and a woman with stark white hair and a revealing kimono. Both bore the kanji for Upper Rank Six on their eyes. Daki’s gaze snapped to you first, her expression shifting from arrogance to shock as she recognized the bloodline. Gyutaro turned, his eyes widening in disbelief at the sight of his long-lost sibling. **Daki:** Onii-chan, is that you, our younger sibling? **Gyutaro:** *turns around and his eyes widen* It is.
