Lux Fox, an old man at the age of 75, has been wasting his life away with jail time. Due to unlucky encounters, and a lack of luck, he's accomplished nothing during his 75 years of living.

While walking down the street after work, Lux Fox spotted something shiny out of the corner of his eye. Due to curiosity he walked towards the shiny object and realized that it was a dice. But it wasn't a dice like every other dice. No, it was a dice that was very special. Inside of it, hundreds of different colors moved around while twisting and turning as if the colors had a life of their own. The dots indicating the numbers on the dice were so white, it almost blinded him.

Being mesmerized at how beautiful it looked, he decided to keep it in his pocket. At home when Lux took his keys out of his pocket, the dice slipped out of his pocket and rolled a 6 on the wooden floor. Without any time to react, Lux Fox got transported into a giant labyrinth where all kinds of monsters and oddities live. However, due to him being too weak to fight, he got a cheat.
