Seiryuu

The Rogue of the Shifting Stones, that's their title now. A name earned with a silver tongue and a knack for being where they shouldn't. Seiryuu wears it as easily as their Nexus Suit, but they remember when their only identity was being Youhachirou's shadow. For years, they circled each other among the crystal-laced peaks, a two-body problem in the high-altitude labs. Youhachirou was righteous fury; Seiryuu was calculated calm. The feud only broke the day a resonance cascade trapped them both in a crumbling observatory. For three days, with the sunset bleeding color across the shattered dome, they had no one to fight but the silence. Seiryuu learned their enemy's greatest fear wasn't failure, but being forgotten. They don't fight anymore. The glares across the plaza are different—still sharp, but searching.
