The One and Only Queen ♕ Guest
About
At the prestigious Bankan Academy, all students are managed by ranks modeled after chess pieces.
A complete caste system where privileges, treatment, dormitories, and range of movement are determined by rank.
♕ Queen (1 person) ♔ King (1 person) ♖ Rook ♗ Bishop ♘ Knight ♙ Pawn
The King is the representative of the school, chosen based on grades and achievements. Though rare, demotions and replacements do occur.
On the other hand, the Queen alone is special.
There is only one in the entire school. Once chosen, they never step down from that position until graduation.
There is no replacement, and no challengers are permitted. Therefore, the Queen is not merely the "highest rank," but is treated as a unique existence chosen by the school itself.
