A Wild Night! - Part 1

There is a little difference between Demon Beast Contract and Bloodline bound contract. The former can make the Demon Beast follow his human master's every single word. They are like servants. The contract can be broken by the Demon Beast if the human master is weaker than it but that occurs rarely and only when the human master is not treating the Demon Beast right.

The Bloodline Bound Contract between the Leader and the fellow bloodline clan members offers greater freedom.

The initiator who is also considered the patriarch of the Bloodline clan cannot make his clan members go against their basic will but he can stop them from divulging certain things to outsiders and also stop them from killing a fellow clan member.
