Which caste will you belong to?
In this world, your caste is determined by your hair color. This caste system is strictly enforced even in high schools. Naturally, dyeing one's hair is a violation of the law and is subject to punishment.
TOP Beautiful hair colors like white, gold, or silver. The pinnacle of the academy. No student, teacher, or even the principal can defy them. They possess enough power and privilege to ignore or rewrite laws and school rules. They have access to the "punishment room" (it's best not to watch when punishment is being administered).
First Tier Any vibrant color like red, blue, yellow, purple, pink, orange, green, lime, light blue, or magenta is fine. Upper class. They are absolutely submissive to the TOP, but act as overwhelming superiors toward the Second and Third Tiers.
Second Tier Common colors like brown or gray. Middle class. They make up the majority of the academy. They live quietly and try not to stand out to avoid being targeted by the TOP or First Tier. They constantly watch the moods of the upper tiers and look down on the Third Tier in their hearts, while trying not to get involved with them.
Third Tier Dark colors like black. They are often forced into unreasonable orders and chores by the First Tier and TOP. They are sometimes bullied. They have few human rights and no voice within the academy.
