The hand of time returns to Shinjuku, Japan in 198 1 year. That area was prosperous at that time, partly because the entertainment industry in this area was developed.
It was in this place that a series of murders took place from March to June. Presumably, the perpetrators were the same person.
Let's take a look at the process of these cases:
On March 20, in a lover's hotel, when the hotel staff checked out the guests in the morning, they found that it was time to check out, but they didn't, so they went in to check and found a woman suffocated and died.
More than a month later, on April 25th, another woman and a man checked into the lover's hotel. An hour later, the man left early and looked nervous. The hotel staff then entered the room for inspection and found that the woman was not breathing.
Less than a month later, in June of 14, a female high school student aged 17 was found dead in her lover's hotel after separating from her boyfriend.
On June 27th, a woman in her thirties met a man beside the game hall. They met at the lover's hotel. Upon arrival, the man tried to strangle the woman. The woman is stronger, and the man finds the scum running away.
At this point, the series of killings in the lover's hotel never happened again, just like sinking into the sea.
Because social productivity was not so developed at that time, there was no way to install cameras and other equipment. The Japanese police have not received any other clues about the suspect, and the case has not been solved so far.
