Whoa, the translation got so much better than chapter 1. Still could get better, but it's a lot easier to read. I just understood that "The forest birds" are actually a troupe of adventurers, and not some strange rental service for travel.
By the way, a manga is usually made to promote the LN. If the manga gets popular, it usually gets better and less "rushed" in its pacing.
They accelerate the pacing a lot and remove "boring" parts to grab the audience as fast as possible.
So I'm not dropping this manga yet. The premise is cliched, but there are some points that could get interesting.
Like the effect releasing her vampire powers has on the maid.
