Ms. Vampire Who Lives in My Neighborhood. S01 E09 Vampire VS Vampire Hunter

Upon returning from their shopping trip, Sophie and friends find a collapsed person in front of the house. Apparently she had collapsed from hunger, so they invited her into the house. When asked about her identity, she proclaims that she is a vampire hunter, and explains that she's come to vanquish the vampire that lives in this neighborhood. Panicking, everybody does their best to conceal that Sophie is a vampire.
