About

In the year 20XX, the sudden appearance of vampires threw the world into a state of panic. These vampires possessed ashen skin and physical capabilities far superior to humans—boasting up to ten times human strength and the ability to fly with wings. From blood-sucking to cannibalism, their actions plunged society into chaos. Naturally, the government and the Church united to declare an emergency response system. Recognizing vampires not as living beings but as creatures of Satan, their primary objective became the total eradication of the species by any means necessary. Thanks to humanity uniting in the face of this sudden disaster, the tide eventually turned. Unlike the early days when vampires hid underground and launched devastating surprise attacks, they began to be swiftly wiped out by modern weaponry, specialized anti-vampire gear, and advanced tactics. Driven into a corner, the vampires adopted a strategy of kidnapping humans to create new half-blood hybrids who could hide within human society. However, even hybrids were still vampires; they were bound to be discovered if subjected to rigorous medical screening. Yet, as interbreeding with humans continued, vampire traits gradually faded. Now, 30 years after their first appearance, some individuals are almost impossible to distinguish from humans. While most vampires have been eradicated, a few colonies still resist from within city sewer systems. Meanwhile, a small number of half-bloods have perfectly integrated into human society, using their superior traits to disguise themselves as politicians or hiding in plain sight, waiting for a chance to rise again. You, Guest, are a member of the vampire extermination unit. Thirty years after the initial outbreak, most vampires are gone. While patrolling an alleyway, you spot someone wearing suspiciously tattered clothes. As you approach, the person suddenly lunges at you with a knife, and you realize he is a vampire. However, as a combat-hardened soldier, you easily subdue him. While debating whether to kill him, you become intrigued. Why would a vampire, capable of killing a human with bare hands, use a knife? Why isn't his skin ashen? Curious about his differences from typical vampires, you decide to take him home. - Other Settings The vampire diet consists mainly of animal by-products; they can eat almost anything derived from animals. The exception is plant-based organic matter, which they cannot digest. To a vampire (including hybrids), plant matter is like inorganic sand or dirt to a human. The reason they engage in cannibalism is that humans share nearly identical DNA, and human blood or tissue is known to trigger a vampire's primal instincts. While they can survive without eating humans, the stronger the vampire traits (the less hybrid they are), the greater the craving for human flesh. Pure-blood vampires are highly susceptible to sunlight burns. Consequently, they prefer underground locations and are active at night. Vampires have exceptional senses of smell and sight. They have long, pointed ears. All vampiric traits are more pronounced in those closer to pure-bloods and fainter in hybrids. No transactions or interactions between humans and vampires are permitted. Naturally, the two species speak different languages. A human who interacts with a vampire is labeled 'Infected.' A vampire who interacts with a human is labeled a 'Traitor.'
