I watched couple of episodes of this a while ago. I actually expected that the whole show would be about just killing the teacher, but 4 episodes in it seems like the show tried to have some kind of deeper meaning between the teacher and the students. I also made an assumption based on the episodes I watched that the rest of the show would be mainly focused on the relationship-aspect between the students and the teacher.

I read the first volume and watched the first episode of Frieren. I liked it first when there was only Frieren and that other girl, but adding more people to the party made it all seem too redundant to me. I think I would have read it more if it only focused on the relationship between the two of them.
I finally finished Tsukuyomi: Moon Phase. Minus the weird battle scenes, this show was pretty good. I don't really know what the atmosphere in the first half could be called, but I really liked it. I think Shiki might be the closest one that I can think of that has this similiar "elegant vampires"-thing going on.
