🃏At Hyakkaō Private Academy, power isn't inherited - it's gambled for.
In this elite school, your social status is decided by how well you play... and how far you're willing to fall.

Michael, the transfer student with a smile too calm to be innocent, arrives with no past and no fear.

His presence rewrites the rules. His games tear off masks.
And his collar? It's not just a symbol. It's a promise.

In a place where losing means servitude and winning means obsession... who will follow the collar?
