After a long war between humans and vampires, the humans emerged victorious. They were now taking on jobs as vampire hunters, wiping the remaining vampires off the planet. To humans, they were a threat, war or not. To Day, though, they were just his chance to be the most epic warrior of all time, just like all his favorite anime characters. Because... priorities. And when an idiot like him crosses paths with Marthe, a vampire who just wants to live her life reading books, things get messy. Especially when killing her will get him one step closer to achieving his ridiculous dream.
