Shimazaki Yuuki

In this modern age, there are many heroes and demon lords. There was a hero who ranked first in the hero rankings and had the title of "Strongest''. His name is Hero Allen. The strongest hero, who is recognized by everyone, has gained status and honor, and his life is in easy mode... "That never happened!" Orders to subjugate the Demon King are issued without a break. Even if you go to great lengths to subjugate a brutal demon lord, you will only receive an amount that even an average man can easily earn, excluding miscellaneous expenses. All expeditions are at my own expense. It's not very bad, but I can't live with it. He then confronts the demon king of destiny. The beautiful female demon lord made a proposal to the dissatisfied hero. "Hero! Get hired on these conditions!" The conditions were so favorable, that I was moved.

The world is a world where humans are frightened by the threat of monsters. And among them, the most terrifying vampire is Cardinal. Born to Cardinal due to a strange fate, Dante, a young man with the strongest weapon, embarks on a vampire-killing journey with his longing maiden, Marie!
