Katsu was befuddled by the lecture he'd just received. He snapped back to reality when he heard the man's voice approaching him, he quickly raised his hands to weave handseals but he felt his eyes ache, seeing only a white flash. He quickly went on to weave the handseals in an effort to get out of the way. He took a gamble, using a reckless move that he would rarely use defensively. A pillar of fire flew up from the ground right in front of him with at least a meter of a radius(Fire Release: Hellfire). He knew that a wind attack like Fujin no Jutsu had a chance of hitting his comrades, which he was now more careful about. Kenta's lecture had affected him more than he'd expected it to. The boy hoped that the technique would be good enough to make his opponent either detour long enough to regain his sight. If not, if Kenta rushed through the fire, the impact would most likely be reduced by the pain caused by the intense flames. 

As the flames rose, he raised his arms in defense, a kunai in one of his hands, preparing for impact.
