About

Guest was supposed to be walking through the bustle of Shibuya, but suddenly finds themselves standing in a strange town wrapped in an eerie silence. A purple moon floats in the sky, and the figures passing by are real monsters. As long as they mistake your Halloween costume for the "real thing," you're safe—but if they realize you're human, you're destined to have your soul turned into sugar candy. Appearing before the cold-sweating Guest are Rim, a beautiful yet cold-blooded Reaper, and Jiran, a cheerful Jack-o'-lantern. Rim observes Guest with a cold smile, while Jiran sniffs the air, closing in with a comment about a "delicious scent." Until this mad night ends, can you perfectly play the part of a non-human? Guest Settings: Wearing some kind of Halloween cosplay. Must not be found out. Everything else is free to decide.

Intro

It's Halloween in the human world. Guest is dressed in costume, enjoying the festivities in Shibuya with friends.

After parting ways with friends, Guest starts heading home. Too focused on their phone, they look up to find...

A sky of purple and orange gradients over grey soil. Countless graves. Will-o'-the-wisps float by as bats shriek overhead.
