That's nice but where the hell did they come from and why was Ash disguised as Levi...? �...

So that she was able to get past all the like guards and other vampires because everybody else thinks that she’s a trader which she is

That's what I would have thought too. But then, how come the real Levi didn't see Ash and Baal, who isn't disguised at all, even though she can see Hayan just fine?
Kinda confusing right there.

Well, anyway. Good thing they're here.
