(Un)fortunately, Ventus has become pretty used to hostility towards moogles, at least from confused newcomers. That's really the only time it's (partially) excused, so while he doesn't catch all of that threat as he walks out of the shop, he notices the tension all the same. As usual, he's more concerned and eager to intercede peacefully than he is about to get defensive.

His own moogle is hanging just behind his left shoulder as he approaches -- habit, since Ven keeps the handle of his Keyblade ready behind his right -- but she stays quiet as her Hero speaks up.

"Hi there! You're new, right?"

Best to start off friendly, as always. If there's anything familiar about the newcomer, Ven can't immediately place it.
