Tokyo Babylon(1990)

It's 1991, the last days of Japan's bubble economy, and money and elegance run through the streets. So do the currents of darkness beneath them, nourishing evil spirits that only the arts of the onmyoji—Japan's legendary occultists—can combat. The two most powerful onmyoji are in the unlikely guises of a handsome young veterinarian, Seishiro, and the teenage heir to the ancient Sumeragi clan, Subaru.
