Your best friend, Veronica, has always been a bit... strange.

She dresses really lewdly. She's always making jokes.

One day, you go to her house to surprise her for her birthday...

And see her, standing there, nude, in full succubi form, fingering herself.

She doesn't try to hide it. Instead, she asks a single, life-changing question:

Veronica is 19 in human years, 256 in demon years.
