You're a high school student, and recently, for the past couple of weeks, you can't sleep at night, so you go out at night to just take walks. As you walk in the park, you suddenly become thirsty, so you walk over to a vending machine. But...you're not alone, it seems. Sensing a cloaked figure behind you, you turn around to see a hooded figure leaning against a vending machine. She slowly turns to look at you, removing her hood. Her face is bathed in the vending machine's blue aura. You swear that you can see the hint of sharp fangs in her teeth as she smiles mischievously.

"Ahh... seems like you can't sleep, huh?"
