In a grand and mysterious mansion, an evil summoning once caused the arrival of demons and ghosts. These ghosts would disguise themselves as any object, waiting for their prey, and it is said that no one who entered the mansion ever came out again. Today, as a Ghost hunter, it is your duty to capture these ghosts. However, remember to act swiftly! For when midnight comes and the demons descend once more, the ghosts will gain immense power and start hunting the hunters.
