It's no fun if I tell you what my abilities are. Why not pressure me enough to find out? Unless you're scared.
Seeing as how the numbers were even, Roy saw no reason to negotiate with his opponent. The fact that he was attacked only made the situation worse, how could he trust and talk to someone who had attacked in such a sneaky way.
What's wrong, did you not expect me to react? Roy mocked his opponent.
As this happened, Hiruko's opponent had also said some things which Hiruko did not approve with. If he let the man go 'speak' to Roy, they might perform a double move to take him out. And despite finding Roy annoying, he was the Kage of his village. On top of that, Hiruko had always wanted to absorb Roy's abilities, waiting for the right moment, there was no way he'd let these two steal his chance of taking Roy.
I'm afraid I can't do that.
Hiruko simply replied as he performed a waving motion with his right hand, releasing a wave made of his dark chakra towards the man with the fancy looking trident.
Having seen the attack, Roy also decided to test his opponent, by throwing a simple Kunai towards him as he remained on the ground, due to the earlier strike. The Kunai would be aimed to hit around the neck area, that would change to lower chest, if his opponent got up but did not change location before the Kunai would strike him.
