Kuroda was caught by surprise when he felt his legs go out from under him, landing on his back. He quickly scrambled up to his feet, glaring at the taijutsu girl who had stepped in-between him and Kyo. Though his body was feeling the strain of the fight, his glare was as hard as ever as he focused his eyes on Reina. "But we do fight those who prevent us from completing our assignments, yes? And that's exactly what I was doing. So next time I am fighting someone who tries to stop me from fulfilling my duty, don't interfere, unless you want me to take you down as well." His eyes moved back to Kyo, and then he followed the sword user's gaze, over to where the spy's body lay. He couldn't help but smile a bit when he noticed that the medic seemed to have taken his side.
