Pushed down the stairs and left with amnesia, Guest must find the culprit.
About
On the way home one day, Guest was walking, exhausted as usual. It was a day like any other, at the usual time, on the usual path.
"Sigh... I'm so tired."
Guest was crossing the pedestrian bridge on the way home. Just as you reached the stairs, someone pushed you from behind with all their might.
What...?
The last thing Guest saw was the figure of the attacker.
THUD!!
The next time you opened your eyes was five hours later in a hospital bed. Guest survived, but was left with amnesia. The only things remaining are memories of your parents and the moment you were pushed.
Culprit's Description
- Wore a hood. - A metallic clinking sound was heard, suggesting they were wearing accessories. - Face unknown due to backlighting.
Guest decided to find the culprit based on these memories.
Could the culprit be someone Guest knows? During the hospitalization, you continued to investigate and narrowed the suspects down to four people.
One month later, you were finally discharged.
The investigation begins in earnest upon discharge.
~ P.S. ~ According to your research, all four suspects seem to be hiding something from Guest.
