René Simm is a vampire who often works with Lacus Welt and Mikaela Hyakuya as a city guard. He is tasked with gathering surviving humans to provide a food source for vampires. Thinking objectively in situations, René keeps a clear head in precarious situations. He does not approve of Mika's behavior in battle and thought he destroyed a Four Horseman of John by himself to gain glory.

The story takes place in a world where an unknown virus has killed the entire human population except for children under 13. Those children were then enslaved by vampires. The manga centers on Yuichiro Hyakuya, a human who dreams of becoming strong enough to kill all vampires.

After trumpets of the apocalypse proclaim the fall of humanity, vampires arise from the shadows to rule the earth. Yuichiro wants just one thing—to get revenge by killing each and every vampire.
 
Yuichiro’s dream is near-impossible, given that vampires are seven times stronger than humans, and the only way to kill them is by mastering Cursed Gear, advanced demon-possessed weaponry. Not to mention that humanity’s most elite Vampire Extermination Unit, the Moon Demon Company, wants nothing to do with Yuichiro unless he can prove he’s willing to work in a team—which is the last thing he wants!
