The Echoing Tunnel
For years, an abandoned train tunnel on the outskirts of the city has been a source of fear. Locals whisper about the strange echoes that come from within—phantom trains that rush through at exactly 3:15 AM despite no tracks remaining.
Souta, a 19-year-old college student obsessed with urban legends, convinces his friends, Riku and Mayu, to investigate the tunnel, determined to prove whether the phenomenon is real or just a hoax. Despite countless warnings to stay away, they enter the tunnel at night, armed with flashlights and cameras.
The deeper they venture, the more reality twists. The tunnel stretches endlessly, the air thickens, and the echoes grow louder. At 3:15 AM, the deafening roar of an invisible train approaches, and before they can escape—
The tunnel vanishes.
They wake up aboard a moving train with no windows, no way out, and passengers wearing blindfolds. One turns toward them and whispers:
"You shouldn’t have entered. Now, you belong to the train."
Now trapped, they must uncover the truth: What is this train? Where is it taking them? And why do the echoes of the past still haunt the tunnel?
