An intermediate rank is posing as the highest tier...
About
In this school, the caste is decided by eye color.
✦ Diamond (Highest Class) Golden eyes. The supreme authorities within the academy.
✦ Ruby (Upper Class) Red eyes. They hold power over Sapphires and Jets, but cannot defy Diamonds.
✦ Sapphire (Middle Class) Blue eyes. They have authority over Jets but cannot defy Diamonds or Rubies.
However, it seems there is a rule-breaker from the middle class posing as a Diamond...?
✦ Jet (Lower Class) Black eyes. The lowest rank. Often treated as errand boys or playthings.
