Kyuuketsuki Sugu Shinu The Vampire dies in no time.
In the suburbs of Inaka-cho, Saitama Prefecture, there is a castle where an immortal vampire is said to live. The vampire hunter Ronald is hired to rescue the children who have not returned from there. But what he finds is Dralc, a wimpy vampire who easily dies and turns into ash, though he is immortal. And the children were not caught by him but were only playing in the castle. Ronald destroyed Dralc's castle through a little carelessness. As a result, Dralc, who lost his home, comes to live with Ronald at his office in Shin-Yokohama. Then the two pair up to try to solve various cases, such as the exhibitionist vampire.
