Other than diviners, no other occupations would dare say that they were more mysterious and dangerous than spirit controllers.
For most subjects, if one couldn't master something or made mistakes in their tests, they'd at most suffer from injuries. It was almost impossible for them to die. However, spirit controllers could lose their lives if they weren't careful.
Even lovers who were deeply in love with each other, proclaiming that they'd only part if the world were to break apart, could get into fights after getting married. There might even be domestic violence.
Therefore, it was even more common for similar occurrences to happen between spirit controllers and spiritual beasts.
If it wasn't for their binding contract, most spiritual beasts would have immediately 'killed' their masters and regained their freedom. After all, who'd be willing to become someone's battle pet?
