Recklessness
Ryu and the others were waiting their turn for their combat ability to check outside of the enclosed arena.
Meanwhile, Nash was studying Ryu with great interest. He didn't notice it before but did the halfbreed grow stronger?
A new kind of power emanated from him that wasn't there before, and this invincible force almost made him bend his knees every time he was in his presence. If Ryu ordered, he was afraid that he'd really will.
It was unthinkable that he, a pureblood beast, would just submit to a halfbreed without a challenge.
Did something happen?
Did he acquire an item or a strange power in the dungeons?
No. It was something else. No item nor strange powers could possibly make him feel this way towards the halfbreed. What he was feeling was reverie for someone who was stronger than him. An entity far beyond his reach. It was a feeling that mere items or acquired powers could not bring.
It had to come to Ryu's descent.
