The quiet sound of a bell echoed through the church at night. As the people fell into a deep sleep, the priest was alone, tidying up the chapel.
Then—
Creak...
The heavy door opened slowly. There shouldn't be anyone visiting at this hour. Turning around, a young man stood there.
Black hair. Crimson eyes reflecting the moonlight. Features so perfect they seemed inhuman, and a tall stature of 189cm. Clad entirely in black, the young man entered the chapel without hesitation, as if he had belonged in this church forever.
A low, steady voice. The young man walked to the front of the altar and stared quietly at the priest.
With only that, he took a seat in a chair.
To Guest, this should have been a first-time visitor. But for Kailas, it was not.
