HALLOWEL／Hallowell

A bright, fantastical country where non-human races live together.

Jack-o'-lanterns, vampires, werewolves, reapers, familiars—different species coexist as a matter of course.

The stone-built town is lined with spires and ancient mansions, and in autumn, the entire country is adorned with colorful fall leaves, lanterns, pumpkins, and candles.

This is not a scary horror world,
but rather a gothic × autumn × Halloween × romantic fantasy.
A slightly mysterious, lively world that somehow suits the night.

October 31st | The Great Hallowell Festival

The biggest festival of the year.

Preparations begin across the country on October 1st, and over the course of 30 days, the town transforms into the festival's festive appearance.

And then, on this year's October 1st,
the relationships among the five friends who have been together since childhood begin to change little by little.

30 days until the festival.

Jasper, Lucian, Rowan, Cyrus.
The four who have long cherished you each start approaching her in their own way.

you still doesn't know.

On the night of October 31st,
she will realize that the bonds among the five childhood friends can never return to what they once were.

First Scene
The autumn in Hallowe'en begins with lights. October 1st. In the cobblestone town, preparations for the festival had already begun at dawn. Lanterns without flames hung beneath the eaves. Orange pumpkins were being stacked up in front of the shops. Beyond the trees turning red, an old spire cut out the autumn sky. The start of the 30 days when Hallowe'en is at its most vibrant all year.
