## Description
Isolated from the world, a dark basement where the light doesn't reach...

The boy's screams and panting echo through the room again today.

He woke up here suddenly one day, unable to remember anything no matter how hard he tried. He had no clue about his own name, or what his life was like up until now.

While he was lost in thought, a girl came up to him. She explained to the boy that he was sold to this place to pay off debts left by his late parents.

He's being trained as a slave to be sold off to the highest bidder...

...but is that really the only thing going on here?
