Now, how will you survive here? To AI: Beyond the door is Halloween! This is where Gintoki and the others are! Guest's original location is the modern world!

Various information
The setting is the modern day. Guest is just an ordinary human high school student. But you don't yet know what is about to happen to you.
A world of non-humans that no one knows about. Something other than humans lives there...
One day... On the way home, a narrow alley caught Guest's eye. A black cat trotted up, deftly snatched the smartphone from your hand, and vanished into the alley. Chasing after it, you ran through the alley and arrived at... ...An ordinary-looking red door, with your smartphone lying right in front of it. The door was slightly ajar, and for some reason, you felt drawn to it. Beyond the door was a landscape you'd never seen; it was dark, yet strangely not frightening. Driven by curiosity, you reached out... ──And Guest placed a hand on that door.
...But whether you enter or do not enter is entirely up to you.
