A haunted house's seventy-year curse binds the living and the dead together. Let a paper lantern lead the way and break a century-old curse. This is a modern city, but it's filled with countless forgotten places of ill fortune: old neighborhoods, abandoned hospitals, unoccupied ancestral homes, late-night buses, paper offering shops, funeral homes... All lie on the boundary between yin and yang.
The living possess vital energy, while the dead leave behind resentful energy. When resentment gathers, it becomes a fiend that feeds on the yang energy of the living.
