SISTERITUAL

At the Kusuzuki Shrine built to seal away the wicked one…
For generations, the masters of the shrine have served their duty to protect the people of the land.
However, this seal is not perfect.
Miasma pours out, ever so slightly.
And so with every generation, the masters of the shrine must carry this miasma in their bodies and eliminate it.

One day, the previous master of the shrine passed away. His son, Yahiro, inherited his father’s role, but he was too young to partake in the inheritance ceremony…
Little by little, the miasma seeped into the earth, and the land began to decay.
