Any other time Bishop would have appreciated Gojyo's light heartedness in violent situations, but he was in "Agent" mode to gather information and boy did he stumble on something note worthy.

He caught every moment of Gojyo's attack, and while he wouldn't go for a sweep against an oni of all things, that fact he pulled it off was one of a few indications of the kind of person this red head is. No fear against a yokai, which means he might have seen them - or something similar before, the way he suppressed them showed he's a seasoned fighter, and then there was the taunt inviting the others to fight. Was he used to being outnumbered or was he taking advantage of Bishop's earlier assessment. Either way, this guy was now on Bishop's radar. 

"I suggest you run." He says picking up more rocks with one hand. "We're on a schedule, a loose schedule, but I'd rather not play. Especially since your buddy with the gaudy shirt tried to pick a fight with me earlier." 

The group looked to the leaner grey skinned oni wearing a bright shirt with a crane and tiger on it. 

"So take a hike before I plant these stones in your eye sockets." His voice was serious and deadly, making his threat far from idle.
