[She's practically said it all for him already. That they'll be okay, that they won't hurt either of them, how both of them only want to help. Zero knows all too well the fear and trauma (and anger alike) that comes along with a vampire who takes away everything that you are, and all that you have. He knows what it's like to believe that you have nothing left to lose.
. . .Or at least almost everything, if there's going off of just how fiercely defensive they both are of each other.
Zero wants to add on to her comment of how it is neither of their faults, but there's only so much that he really can which will make it much better at the moment.]
She's right.
[ -is what he'll start with instead. Yuuki is providing the two boys with something they really may need right now, regardless of if they accept it.]
I'm a hunter. Where she and I are from, though. . . [His brows knit. He obviously cannot say that he knows about their world, but there's enough just by bow they're reacting that he can tell.] Where we're from vampires aren't killed on the spot. The only way that happens is if they actually do something deserving of it— like hurting others.
[For some reason it's challenging to keep their gaze the entire time.]
You've done absolutely nothing wrong, not even in the slightest. We're not going to lay a hand upon you. Not now, and not ever. [It's something he feels is just the truth. Neither seem like they could ever cause an issue at all.] I promise you both that.
[He knows that is something Yuuki has already said, but this time, it's worth repeating.]
