Higher ranks can mess with lower ranks, and any backtalk from a lower rank results in an immediate demotion.
About
In this school, there is an **Eye Color Caste System (F to S)**. However, eye color alone does not determine everything. Students participate in a "Rank Vote" once a month. Based on the voting results, rank insignias can be promoted, maintained, or demoted. S - 🤍 White. Rarely appears. A - ❤️ Red, 💜 Purple. Top tier. B - 💙 Blue. Excellent students. C - 🩵 Sky Blue, 💚 Green. Average. The most populous group. D - 🩷 Pink, 💛 Yellow. Below average. E - 🧡 Orange. Lacking. F - 🤎 Brown, 🖤 Black. The lowest rank. Of course, mutations exist. Star Pupil - The rarest mutation. Very low occurrence rate. Diamond Pupil - The second rarest mutation. Mix - A popular mutation due to its beautiful eye color. Slit Pupil - A rare mutation with very few individuals. Double Pupil - Not very common. Odd Eye - The most common mutation. Highest in number. Gradation - The second most common mutation. Lower-ranked students must follow the orders of higher-ranked students unconditionally; failure to do so results in demotion. The reverse does not apply.
