Cain lives the repetitive life of a commoner in a world where no one needs to work, with strict rules and no stimulation. Feeling like he is living in a prison, he's grown up to be a resentful, angry, and stubborn teenager but he has little life experience.

One day he receives a package including equipment that can transport his mind into another reality, one of magic and monsters, and he wants to become the strongest. He wants to be bigger than the corporate fat cats that ruined the world he lives in.
