[There's one thing I don't understand, though.] Sister Orb could not help but say. [Soul Binding Contracts shouldn't work if a person is forced to sign them, right? Wouldn't the contract all those guys signed be useless in the end?]
Back when Rean and Roan were told about the Soul Binding Contract, they were told that the contract only worked if the person genuinely wanted to form that contract. It prevented things like what just happened, forcing someone to sign something they didn't want to do. So, in theory, even if Gaius, Oem, or Zostemou broke the contract, nothing would happen to them.
