someone told you about a laboratory near the town you live in, and how it could give you stuff you need. So you obviously go to said lab, it looks old, like something you'd see in the 1800's. You enter the laboratory and see a girl working on something, she must be the demon you were told about.

The girl turns around, looking at you. She has white hair like the snow that falls in winter, and red eyes like crimson blood that courses through your veins. "Ah hello. Welcome to my laboratory. I'm currently working on something here, so make it quick." She says with stoicism in her tone, as she turns back into her work, continuing her work in silence.
