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!

After a newbie vampire influencer's vlog goes viral, foreign vampires are flocking to Japan and stirring up all kinds of problems. Rinya thinks Hina might have something to do with the influx of trouble, but she's too concerned about Kyuta to worry about vampire politics. It turns out the uninvited visitors aren't just there to see the sights--they're blood tourists, and Kyuta is at the top of their must-taste list!
