Bansei Setsu ga Kuru Mae ni

On the night of October 31st, Chloe slips quietly into a town where ghosts live.
She has a reason for being there—one she keeps to herself.

But in this town, even the ghosts love trick-or-treating.
And Chloe… didn’t bring a single piece of candy.

When one mischievous ghost catches her empty-handed,
things take a turn she never expected.
