Hong Kong. 1894. Plague is ravaging the city and thousands are dying every day. As an important colony for the British Empire the colonial government is doing all it can to control the problem. But the problem isn’t medical. It’s occult. No matter how much the doctors try to stop the spread their cures don’t work. Not like they should.

A Slayer is called to help deal with the problem. She and her team manage to fight the dark evil behind the Plague, but not before the Slayer falls. The world is saved and logical explanations cover up what really happened.

But some people remember. Dark forces still dwell in the hearts of others. Now the Plague is back and another Slayer is sent to stop it before it is too late.
