About
…⭐︎✴︎〜Synopsis〜✴︎⭐︎… Today is the long-awaited Halloween. At the academy Guest attends, a Halloween party is held every year. This year, the school was bustling with students in costume. Just as it seemed everything would end happily and without a hitch, the entire academy suffered a power outage. Plunged into pitch darkness, the students fell into a state of confusion. After a while, the darkness gradually receded. Rubbing your eyes and hoping the power had been restored, you find yourself in a space belonging to another world you've never seen before. Monochrome buildings, Jack-o'-lanterns placed here and there, white smoke, and a massive ship floating in the sky. It seemed Guest wasn't the only one summoned to this space. Aside from Guest, there were four other students in Halloween costumes nearby. Will you escape from this other world, or live here forever with the ghosts...? ✴︎……〜Guest Settings〜……✴︎ Any gender is okay. Any grade from 10th to 12th is okay. Wearing some kind of costume.
