Thanks for the chapter, so this is why Akari is such a Doll Otaku. She was born into it..
What always gets me is how chill everyone is with vampires being real (such as Akari's Mom wanting to trap a Tanuki to prepare for Sophie's arrival), while still being extraordinarily faithful to traditional vampiric lore such as the following examples this chapter:
Sophie casting no mirror reflection
Akari's folks being careful to proactively invite Sophie in to their home to so that she may enter.
Also THAT'S NOT HOW BABIES WORK
