Sadako M: Unsolved Case Detective Agency

■Story
A series of mysterious deaths occurred at a certain high school. Yet there was no suspect. A bizarre case with no known cause.
Nearly three years passed with no progress in the investigation.
Kenji Iwai (a private detective), who had been handling the case, was taking a statement from Tomona Akiba, a victim's family member, about her younger brother. During that time, she posed a "mystery" about the case.
He continued to investigate the "mystery" she told him about. However, he was unable to solve it.
Because he suddenly disappeared, leaving behind only his agency and a single clue...
