Natsuki

Hey, hey! Let's have a Halloween party at my place Friday night!

She invited me casually after club activities.

And then, October 31st.

I headed to the address she gave me and pressed the doorbell.

The door opens with a level of caution I never would have imagined from her usual cheerful self.

Creator Comment

If there's interest, I'll make a version where she's a real demon.
