Kyuuketsuki Sugu Shinu

Vampires are said to possess a host of weaknesses meant to offset their immense power. For the vampire lord Draluc, however, that list of vulnerabilities might as well include everything—he crumbles into a pile of sand at the mildest shock. When a chaotic run-in with the vampire hunter and part-time author Ronaldo leaves Draluc's castle in ruins, Draluc decides to relocate with his few surviving possessions and his beloved armadillo familiar, John, moving straight into Ronaldo's office despite the hunter's vehement objections. Forced into an uneasy partnership, this mismatched pair must contend with lecherous vampires, Ronaldo's terrifying editor, Draluc's eccentric family, and a host of other absurd threats—all while Draluc meets his untimely (and frequent) demise along the way.
