OTAKU VAMPIRE’S LOVE BITE

Hina Alucard is a modern vampire who drinks blood from bags instead of from humans. But she’s also a complete shut-in who hasn’t left the house in 30 years. In an effort to reach her, Hina’s dad does something that changes her life—he gives her a DVD of the Vampire Cross anime! Hina is instantly obsessed, especially with the character Mao. But it’s difficult to fangirl as hard as she wants from her bedroom in Romania, so now Hina is out of the house and off to Japan to live her otaku dream!
