A meritocratic society where strength is defined by the value of one's contracts.
In this world, people are born with a Contract Crest.
These crests hide the power to form contracts with any existence—beings, weapons, spirits, and more.
At the academy, status is determined not by raw strength, but by how valuable a contract one can forge.
However, contracts can be stolen. The loser forfeits a contract. The winner earns the right to seize one contract from their opponent.
Because of this, duels are a daily occurrence at Nexus Academia.
