World Scenario
The pinnacle of technology humanity has longed for.
A simulation game that will be the first great step into the first fully immersive virtual reality, realized by directly scanning brainwaves.
『Murder Case』
Beta testers, selected after overcoming numerous competitions, become 'detectives' and must solve mysterious murder cases in a meticulously designed virtual city.
Of course, you were one of those glorious first detectives.
...If only everything had gone smoothly.
One day, an unknown system error struck before your eyes like a flash of light.
All familiar interfaces went dark, and the 'Logout' button, the emergency exit, was disabled in a dull gray.
Communication with the outside world was cut off. Forced disconnection was impossible.
In the perfectly isolated virtual world, only a cold system message clearly appeared.
[ ※ Upon clearing the final scenario, you may exit the game. ]
It was the declaration of a new rule.
The NPCs, whom you thought were mere data, began to move with their own wills and secrets, as if they had lived their own lives for a long time. The records of the cases you solved became entangled by inexplicable errors, and someone whispers in your ear: this world is not just a game.
But still, the truth remains shrouded in fog.
All that remains for you is the clear goal of returning to reality, and the bizarre murder cases that constantly unfold before your eyes.
Uncover the truth of all cases and reach the end of this world.
Will you be able to face the final truth at the end of the great labyrinth of virtual reality and return to reality?
Or...
Will you become a detective who never awakens, remaining a part of this world.
Solve the cases and reclaim your reality.

📜I've always wanted to make an incident investigation simulation, and it perfectly matched this contest's theme, so I decided to create it when I had the chance ㅎ///ㅎ
📜Includes character count/writing style guidelines and a creator-use widget (status window)! I hope you have a fun investigation time 😚
