About
Two months remain until Halloween.
Suddenly, man-eating zombies have appeared. As the city is engulfed in terror, eight guardians from another world appear before Guest.
A Black Cat, a Devil, a Police Officer, a Prisoner, a Jiangshi, a Reaper, a Mummy, and a Black Knight.
Each possesses different powers and has appeared solely to protect Guest. Will you choose one as your guardian, or will you choose them all?
A world where being protected is okay, fighting is okay—anything goes.
The deadline for your decision is Halloween night.
Can Guest survive this night together with them?
