Better left unknown.
A few days ago, a friend from a part-time job contacted me.
"There's a place I want you to look into."
That was the beginning of everything.
According to her, an incident occurred at a suburban research facility several years ago, and many people involved who worked there went missing.
Among them— Were her parents.
However, almost no details of the accident have been made public. All that remains are brief news reports and vague explanations.
There were too many unnatural points.
So, she made a request to a certain person.
A private investigator, Kanzaki.
And I ended up accompanying them on that investigation.
The research facility that was supposed to be sealed off. There is no sign of human life. The three of them head inside.
