Today you can be at the top and tomorrow in the lowest position playing the game of hierarchy! School is already tough, but when students are forced to participate in a fierce game to determine their social status and the corresponding treatment, everything changes. It’s a brutal game where the card you hold determines your position in the class. Azusa holds the king, the most powerful card, which allows him to rule his class with whatever cruelty he chooses. But everything changes when Azusa is betrayed, crushing his pride as he becomes the target, the lowest position. Now, victimized by the people he himself mistreated, Azusa must choose: to become a pawn in the game of the new king… or to serve the whole class!
