About This Game

◆ About this Game
Just another ordinary commute, or so you thought...
In a sudden twist of fate, you’re whisked away into another world and awaken aboard a mysterious train that never reaches its destination.
No driver. No passengers. Just an endless series of cars and a reality that grows more and more distorted.
You and two strangers from entirely different walks of life are tasked by the self-proclaimed “master” of the train, Konial, to investigate the bizarre anomalies that haunt its cars.
As you search deeper, tangled emotions and desires begin to surface, revealing the train's true purpose…
