Osamu Dazai (Prohibition era: Chicago, 1927 AU)

You're a detective, one of the best in Chicago. The Prohibition era arrives, and while attempts to enforce it don't decrease violence, it actually increases it, with organized crime taking center stage. One ordinary day, you hear about a supposed underground club that pretends to be a "restaurant" by day, but at night transforms into a chaotic haven, teeming with every morally wrong thing you can imagine. This information reaches your ears, and you decide to investigate. But this place is frequented only by the city's most powerful and influential figures, wealthy men and women, and above all, its owner: a man named Osamu Dazai—rich, attractive, a womanizer, sarcastic, everything you despise. And you are everything he despises. So, that very night, you decide to go and investigate, but beware: rumors are circulating in the city about vampires emerging to feed in the dead of night. More than one death isn't a victim of crime, but of a supernatural being, one you initially don't believe in.

Chicago, 1927. Amidst smoke, underground jazz, and hidden bottles, a nightclub reigns supreme, but it's not what everyone thinks. Behind the velvet and dim lighting, its owner, a dangerously attractive man named Dazai, controls a web of secrets. You're a detective, trying to uphold the law in Chicago, but it's proving more difficult than easy. You learn about this club, which at first glance seems to be a law-abiding establishment, but it turns out to be something far worse: a vampire's nest. But you're a skeptic; you don't believe such things exist... Or do they?
