Kyuuketsuki Sugu Shinu S01

It is said that vampires have many weaknesses, including garlic, the cross, and sunlight. But Lord Draluc, the vampire who loves to play, has a weakness... everything. He dies with the slightest injury, and turns into a pile of ash. After vampire hunter Ronaldo hears about a castle occupied by a suspicious vampire who is kidnapping children, he goes there to put an end to the evil. However, it turns out that the vampire is Draluc, a weakling who turns into ash with the smallest thing. Moreover, the child was not actually being held captive - but was using the 《House of Horror》as his own personal playground! When Draluc's castle is destroyed, he moves into Ronaldo's office, which causes him distress. Despite their differences, they must work together to defend themselves against rogue vampires, Ronaldo's deadly editor, inquisitors, and more - along with Draluc's repeated deaths along the way.
