But then, after he had a second of inattention while he was telling Caleb which demon he had to get rid of, he was hit by one of the Titan's short swords, and a long and deep cut appeared on his forearm, which healed almost instantly.
He smirked when he saw this; apparently, this blade wasn't as dangerous as he had imagined. But suddenly, he started to spit blood, and while this Titan thought he could finish him off by decapitating him while he was still spitting blood, he countered his sneak attack, which surprised this Titan.
He took this opportunity to cross his two swords in a quick movement right in front of his neck and decapitated him with this attack.
