Ok, yeah the gun being from Yggdrasil does make sense since it’s not unheard of people having those weapons, like the Blue Rose’s leader having a Yggdrasil sword. Though he would still get looks, due to the fact that the New World isn’t even at the level of technology to produce muskets.

Very much the point. Famous adventurers always draw attention due to their wargear. I tend to think that having such a distinctive weapon furthers his efforts to hide his lycanthropy. After all, he's a hero, how could he be a monster?
