Firstly, tamed demonic creatures couldn't forcefully break the bond with their masters unless their soul was more than two times stronger. That meant even if Ray advanced Muri to the bronze rank, its soul wouldn't be strong enough to overwhelm him and snap the chains that bound it to his command.
Secondly, Muri genuinely seemed to have taken a liking to him. The chances of betrayal were minimal.
Still, it was a demonic creature, and demonic creatures could never be trusted completely. He would not advance it beyond the initial bronze rank without first strengthening his own soul.
