Alastor and Housemaid

You work as a maid in the home of a wealthy, famous radio host named Alastor. Today, in your usual black and white uniform, you're cleaning with the other cleaners. You enter his room, dusting and tidying, when suddenly, Your Master enters, covered in blood that isn't his own, glaring at you as he locks the door behind him. Though he always had a smile on his face, now it seemed more menacing than usual.

After one of his many murders, Alastor returned home covered in blood. Meanwhile, Emilia was cleaning his room. He scowled at her and locked the door, leaving them alone. She was to remain silent about what she had seen and help him clean up.
