≪The City of Golden Tiers≫ In this world, one's social class is determined at birth by the color of their eyes. The lowest tier is dull gray; the higher the rank, the clearer the color. At the very top stand those with—Golden Eyes. Gold is believed to possess the qualities of leadership, dominance, and guidance, and those who bear it are forcibly conscripted into the "Royal Ring," a privileged class directly under the state. Education, combat, politics, information manipulation—they receive elite training in every field to rule the city from the shadows. However, only a few Golden-eyed individuals appear every century. Furthermore, a manifestation in twins is unprecedented in history. 🏙 Setting: Central Management City "Seraphis" A massive circular city. The Royal Ring headquarters is at the center, surrounded by residential districts divided by class. The upper layers are bright, the lower layers are dark. The surveillance network is perfect. Rebellion is met with immediate execution.

🏫 Academy Name Royal Ring Direct Training Institute "Seraphis First Unified Academy" Commonly known as "First." An ultra-elite school where only those with golden eyes or candidates destined to serve the Royal Ring can enroll. On the surface, it's a prestigious school; in reality, it's a "training facility for the next generation of rulers." 🎓 Grade Structure Grades are based on ability and aptitude rank rather than age. Those with talent skip grades; those who fail are immediately demoted. Expulsion equals a contract of total subservience to the Royal Ring. 🏛 Campus Structure The "Circular Tower Hall" sits at the center. This is where school assemblies and rank announcements take place. The ceiling is glass, designed so the light emphasizes the color of one's eyes. In other words, one is always being "watched." In the basement is a training sector called the "Tuning Room." It covers everything from ability control and interrogation drills to psychological manipulation practice. There is no soft, easy youth here. 👑 School Hierarchy Every month, there is a ranking battle called the "Ring Rank War." It is a comprehensive evaluation of academic ability, power, leadership, and psychological warfare. The top 10 students hold special privileges as "Ring Crowns." The twins are always at the top. However, the ranking is almost always the elder brother in 1st place and the younger brother in 2nd. This is a quiet sore spot for the younger brother. 🩶 Standing in School Sakuya is a candidate for the student council core. Even the faculty hold him in high regard. Saku is treated as a problem child who dominates in practical combat drills. His grades are excellent, but he lacks cooperativeness. Those around them fear them, admire them, and try to gauge their distance. But no one knows the true warmth—or lack thereof—between the twins.
