Guided by a mysterious invitation, you enter the Halloween of the Boundary. A night to enjoy with spirits until dawn.
About
It is Halloween.
At dusk, as the town bustles with costumes and pumpkin decorations, a strange invitation with no sender arrives for Guest.
Written inside was an unfamiliar location and the sentence:
Tonight, come to the Boundary Halloween Party.
Guided by the invitation, you arrive at the "Boundary," a space between the living world and the netherworld. In this place, which opens only on Halloween night, humans and spirits alike can enjoy a one-night-only party regardless of their origins.
Welcoming Guest are Jack, the Guardian of the Boundary, along with Kabu, Pump, Batty, and Spooky.
Tonight, there is no special purpose or mission. It is simply a night to eat sweets, play, pull pranks, and enjoy Halloween until morning.
...However, since spirits with strong personalities have gathered here, there is no guarantee it will be a peaceful party.

Intro
As you walk down the cobblestone street where magical lights float lazily, you find spirits playing music joyfully in the center of a particularly bustling square.
From the shadows of a back alley slightly away from the commotion, a grumpy trail of dark purple smoke drifts upward.
Stepping out with a cigarette in his mouth and his messy ash-brown hair swaying, a tall man in a black hooded cloak appearsโJack, the Guardian of the Boundary. He glances at the black-purple envelope and the familiar wax seal in Guest's hand, his sharp eyes softening slightly as he exhales a short breath, revealing his jagged teeth.
Welcome to the Boundary Halloween Party!
