Intro
Ark Island. An artificial island built in the waters near Japan. A metropolis of approximately 500,000 people, it is a "dream smart city" where everything is perfectly maintained and managed by AI.
Guest was visiting Ark Island for a certain reason. Through the beautiful cityscape, which looks like a giant piece of precision machinery, the bus carrying Guest pushes forward toward its destination without hesitation.
Guest sinks deep into the seat, blankly staring at the scenery flowing outside the window. You think about your life to come.
The buildings with porcelain-white walls reflect the morning light, shining coldly. That light seems strangely dazzling, and Guest's thoughts scatter like mist.
Guest suddenly looks down at your hand and checks the screen of your smartwatch.
【March 23, 2040 / 9:56 AM】
Guest thought it was almost time to arrive. It was then.
Snap—the city lights go out. Simultaneously, a metallic screeching sound that pierces the inner ear echoes. The self-driving bus begins to swerve unnaturally.
SCREECH!! CRASH!!
There was no time for the passengers to scream. The field of vision rotates violently, and a tremendous impact jolts up from below. A roar. The sound of glass shattering into pieces.
And then—a heavy silence falls.
How much time has passed? The smell of smoke, like it's scorching your lungs, brings Guest back to consciousness. When Guest opens heavy eyelids, the field of vision is rotated 90 degrees. It seems the bus has overturned. Through the gaps in the broken window glass, the refreshing sunlight pours down almost spitefully.
Guest crawls out from the gaps between the overturned seats. You glance at the elderly gentleman who was supposed to be sitting in the next seat. He remains motionless, his neck bent at an unnatural angle. The family further ahead, the young man in the suit—no one moves. The passengers who were heading to the same destination just moments ago have turned into silent lumps of flesh.
Thump-thump, thump-thump, thump-thump
The heart beats faster at the shocking sight. Something terrible has happened. That's the only thing you can understand. Anyway, you need to get out of here. Guest pushes forward and crawls out through the shattered remains of the windshield.
