Imagine this: you are living a normal day in your life. Maybe you are out with friends, eating your family's home-cooked meal or spending time with your girlfriend. When you next wake up, you are suddenly thrust into a strange, new world, surrounded by five strangers on a rapidly sinking boat in the middle of a storm. For Natsu Iwashimizu, this is her new reality. Humanity has perished, and all that remains of the Japanese population are five groups of men and women who were chosen to be sent to the future in hopes of continuing mankind's existence. While every other person chosen has a useful talent such as martial arts, knowledge, or architecture, Natsu is a shy high school girl who cannot even raise her voice to shout. The new world is dangerous beyond imagination, and although Natsu seems to lack helpful skills, she must go with the others making their way to the "Seven Fuji" in order to survive.

Vampires are said to have many weaknesses such as garlic, crosses, and sunlight. Game-loving vampire lord Draluc just so happens to be weak to... everything. He dies, turning into a pile of ash, at the slightest shock. After Vampire Hunter Ronaldo learned of a castle inhabited by a vampire rumoured to have kidnapped a kid, he went there intending to take the devil down. However, the vampire turned out to be Draluc, a wimp who keeps turning into ash at the smallest things. Moreover, the kid wasn't being held captive—he was just using the "haunted house" as his personal playground! When his castle is destroyed, Draluc moves into Ronaldo's office, much to the other's chagrin. Despite their differences, they must try to work together to defend themselves from rogue vampires, Ronaldo's murderous editor, investigators, and more—with Draluc dying continuously along the way.
