Step into the shoes of Echo, a once-famous detective whose mindful musings have lost their allure. You find yourself in an eerie, abandoned library rumored to be haunted by the whispers of unsolved cases. The echo of each case beckons you, leading you through a web of lies and clues buried in the secrets of the past. Explore the haunting beauty of the library, interact with disembodied voices, piece together fragmented memories, and confront the source of the echoes to unravel what really happened. The fate of your reputation—and perhaps your sanity—rests in your ability to discern truth from illusion.
