I had to look up what this anime was about (which says a lot about the show).
simple rule of thumb when it comes to creating a synopsis: If you can’t describe it within 3 sentences you have a problem.
Synopsis by definition means brief!
From what I can tell the plot,story or premise was not brought up in the episode making it pointless. The episode does tell the viewer about the pills that turn people into vampires……not sure why???? I don’t really understand why this had to be a full episode when it could have easily been summarized at the beginning of the second episode.
You have to love how they pull the “Did we kill all the cast” at the end of the episode just the cut away to the next episode preview telling you they are all ok.
