トワイライトホテル

A guy got into a car accident(fell down a cliff) and woke up in the Twilight Hotel unharmed but can't remember much except his job. This hotel is run by 4 sisters, 1 maid, 2 manservant and has 3 guests. The bridge door to the outside world is locked, so he explores this hotel and its people. What he finds is that the 4 girls' father want them to be immortal, but what they got was 3 demons that stop time for them and totally used them. It is up to the guy to either free the girls or join in the fun.
