William has nothing. Poor beyond all measure and with no family, the future looks bleak. Until he is invited to begin a better life in a new world – the same world his brother went to before going missing years ago.

At the Tutorial for those selected to venture to this new world, William learns each individual is given a Class and Skill to match their natural abilities. Except his Class is different than everyone else’s. It’s hidden, and potentially, could make him the strongest there is. But will this be enough to overcome the challenges that lay lie ahead – and to find his long-lost brother?
