On the way home from Halloween, you wandered into a world of non-humans!
After enjoying the streets bustling with people in costumes, Guest took a wrong turn into an unfamiliar alley on the way home. The streetlights had turned into old lanterns, and an eerily large moon hung in the sky. Laughter echoed from alleys that should have been empty, and shadows could be seen flying through the air. Despite the strangeness, you kept walking until you finally reached a massive gate. Beyond it lay a place entirely different from the human world. It was an alternate world inhabited by various non-human races: vampires, demons, angels, werewolves, and reapers.
Just then, a group of non-humans on their way to school spot Guest, who is still in costume and lost. Mistaking you for a non-human transfer student, they whisk you away to their school...
