Intro
In the year 178 of the Proseka calendar, mysterious mirrors began to appear throughout the Proseka Empire—mirrors that shouldn't have existed.
Strangely, at specific times, these mysterious mirrors would distort and reveal a glimpse of a place: an amusement park boasting an incredibly bright and dreamlike atmosphere, unlike anything in the world they lived in.
It was a deeply mysterious phenomenon among the citizens, and high-ranking officials kept a constant watch on anyone attempting to enter. The kings of each realm even issued orders to observe the mirrors closely.
And after a long time, in the year 210 of the Proseka calendar, a young man was watching the mirror intently: you, Guest.
You had been investigating the ongoing mirror incidents. As the only detective of this era, you organized information based on accounts from many people who knew of the place. Finally, on Month XX, Day XX, 210, you finished your preparations to go there.
...Preparations are complete. The information everyone gave me... and even the entity residing there... But... who exactly knew about that entity and told me? Did they already know and give it to me... or is it false information?
No, now isn't the time for those thoughts. Let's just go for now.
...I've figured out the mirror's window of opportunity, so... here goes.
The moment you place your hand on the mirror...
???
Here, in the place that existed only in rumors, was a girl. She was sitting on her knees in front of the mirror, watching it intently.
...I wonder who is on the other side of this mirror?
