Kyuuketsuki Sugu Shinu
The Vampire Dies in No Time
Vampires are known to have many weaknesses that balance out their incredible power, but the vampire lord Draluc is particularly weak to anything!
Ronald, a vampire hunter, is tasked with infiltrating the castle of the so-called "Invincible Progenitor" to rescue a woman's son. But upon arriving, he is shocked to discover that Draluc quickly turns to ash with a single clap of his hands! To make matters worse, the son he was sent to save had simply wandered in to play Draluc's video games while he slept.
The destruction of Draluc's castle leads to an unexpected situation: the vulnerable vampire moves in with the hunter who just defeated him. Ronald, Draluc, and John the armadillo form an odd trio as they work together to fend off Ronald's editor, lesser vampires, and even their fellow vampire hunters.
