In the heart of a bustling city stands a mysterious place called the Red Dust Teahouse. From the outside, it looks no different from an ordinary teahouse, but within its walls lies a secret unknown to the world. Legend has it that the teahouse was founded by a master who studied the ways of yin and yang and could communicate with both the living and the dead. Its business is unusual, too: by day, it serves the living, and by night, it serves the dead.
