1x4 - Ms. Vampire Who Lives in My Neighborhood.

As Akari is walking home at night, a winged person passes over her head. Thinking it's Sophie, she chases after them, but it's a girl with golden hair in a ribbon. She says that she's a vampire named Erie, and that she's looking for her friend Sophie. Upon hearing that, Akari takes her to Sophie's house. Erie's overjoyed to see Sophie again and hugs her, but Sophie is anything but thrilled.
