Yukine blinks at that question - out of everything, that was probably a topic he was least expecting to get asked about.

"Free will, eh? Yah, we have it." He grins at her reassuringly, but thinks for a moment before expanding on his answer.

"There are some ways that we're limited, but yes, we have free will. I don't have to stay by my god's side. I can resist changing to my vessel form when called. Even when I am a vessel, I can choose to not cut well." He glances away for a moment at that. Now, it is something he can look back at and regret, a little.

"But we are bound to our god. For instance, now that I have the name 'Yuki', I can't leave Yato for another god unless he revokes my name. Well- I could, but that would mean choosing to be a nora- a stray. And... that's a whole other matter." His expression goes sour at the very mention of it. Please don't ask further.

After another thoughtful pause he continues, "That's part of why I'm telling everyone to get along with their partners. Shinki are meant to be at their god's side, and gods are almost defenseless without their shinki. So it's kinda hell if we don't get along." Been there done that.

He then looks up at her questioningly. "Does that answer your question?" He kinda didn't mean to go so long there.
