Athinar saw the glow surge through her body a split-second before he chose to jump backwards, attempting to get away from the flames. While not entirely successful, he did manage to turn his body away, and tuck his head and arms into his body, leather of his outfit taking the brunt of the damage. While still burned, it wouldn't reduce his effectiveness in combat. As soon as he was launched into the air by the shockwave, he threw the katana at the woman, and performed a flip worthy of Errol Flynn. As he landed on his feet, burns causing his left arm to become a burnt, ashy mess,  smoke trailing from his outfit, he held out his hand, and summoned the blade. Winking at the girl, he took a sword stance, and held the Blade of the Void in both hands, waiting for her to approach.
