Chibi Vampire, Volume 5 (Chibi Vampire #19-22)

Karin continues to come to terms with her feelings for Kenta, but her flirting will have to be put on hold for now. Karin's grandmother is in town, and that's enough to put her entire family into a panic. Elda Marker is no silver-haired, cookie-baking matriarch. She's a hot and heavy vampire vixen with a taste for blood, but a distaste for everything else having to do with the human race. So how can Karin possibly tell her about her new human almost-sorta-not-quite-boyfriend? It's going to be one freaky family reunion!
