Yin and Yang Twins, Brother and Sister Who Catch Ghosts

Yin and Yang have two paths, and humans and ghosts have their own paths. No one knows that the old coffee shop in the city that has been open for many years is owned by a pair of young Onmyoji brothers and sisters. When the first cup of coffee comes out of the oven in the morning, they are ordinary shopkeepers guarding the shop; when the clock strikes midnight, they become ghost hunters walking on the boundary between yin and yang. The kitchen covered with talismans hides magical tools for soul-transmitting souls; under the warm yellow light, there are the endings of countless resentful souls. They took over one business after another and passed away one wandering soul after another, but they didn't realize that they had already entered a huge puzzle that spanned Yin and Yang. When the resentment in the city breaks through the border, this small coffee shop is the last barrier in the world.
