"Monster beasts are naturally violent; how could they be so easily controlled? Once they find an opportunity, masters being devoured by their own beasts is a common occurrence."
"Even among fourth-rank monster beasts, the Dream-Devouring Wolf is at the very top, with the potential to break through the fourth-rank barrier and become a fifth-rank great monster. Although this one is not yet fully grown, it would be nearly impossible for the youth in blue to subdue it on his own. If I'm not mistaken, the youth in blue must have had the help of a powerful expert to capture the Dream-Devouring Wolf."
"A monster beast not subdued by one's own strength carries an even greater risk of turning on its master."
