Omega Vampire

The year is 20XX in Yokohama. Vampires and humans have reached a fragile public coexistence, enabled by EX-BLOOD — an artificial blood substitute developed by the Aoi Research Firm. But many vampires still prefer the real thing and continue to assault humans. Meanwhile, some humans have discovered that drinking vampire blood produces a drug-like high, leading to widespread vampire hunts. Into this volatile balance steps Moriya Keiichi, whose life is saved after a near-fatal accident by a drug that uses vampire healing — at the cost of transforming his biological attribute from Beta to Omega. His new pheromones attract vampires to him. A possessive Alpha vampire named Ooizumi Genma saves his life and Keiichi, who despises vampires, realizes he has become something between human and one of them. A boys-love adult visual novel.
