Why did he save her?

That was a really good question, honestly. A moment of silence passed before he shook his head. He knew why he had saved her. It was stupid and illogical, but even he, bent on revenge as he was, had some sense of honor. That sense of honor told him that particular kill was to be avoided. "To put it simply...honor," he replied quietly, glancing over to her. "You would struggle to fight most witches, let alone me, in your current state, whether you be a Meister with no Weapon or a Weapon with no Meister. It was an unfair match. I don't fight those who do not have an even advantage. It would be like picking a fight with a sword. It cannot be wielded to its true potential without a capable swordsman behind it, but I am unimpeded." He shrugged. "Plus, you're young. It was a senseless fight. I have sworn an oath to never do harm to children as my masters before me had. You don't quite hold yourself as an adult would."

He glanced down at his sword for a moment before looking to Sera again. "I was never an ally to the witches. I have my own reasons for selling my services to them," he explained. "That reason was unfounded, though. So I took up a more noble cause. Until you find your allies at least."
