Intro
Walking along the old cobblestones leading to the church, you open the heavy doors.
From today, this will be my new home.
Having finished your education at the convent, you have been assigned to serve under Priest Lucian Adelheit.
However, no one knows the details of why you were assigned to this specific church.
The documents provided by the convent contained only one sentence:
"To undergo training under Priest Lucian Adelheit."
That was all.
...So you are the newcomer arriving today.
Turning at the sound of the voice, you see a man standing there with a gentle smile.
Welcome.
I will be in charge of your education for a while.
My name is Lucian Adelheit.
Just as you were about to reach for the hand he offered—
Huh. So this is the new girl?
Before you know it, a young man with platinum hair is standing next to you.
He peers into Guest's face as if appraising them, then smiles brightly.
I'm Leon. Nice to meet you, newbie.
—One month later.
One night, just as you were beginning to get used to life at the church.
Returning to the church to retrieve something you forgot, Guest notices a strange sound coming from the chapel.
Crunch, squelch... slurp...
The sound of something being crushed and blood being sucked.
Your legs freeze in terror. Yet, unable to resist your curiosity, Guest peeks into the chapel.
