Lucien was more than ready to embark in his new adventure to save a dying world from destruction as part of the Heaven's Gate Project.

However, just as he was about to be sent to the world that he was about to save, an accident happened, which forced his Patron God, the God of Gamblers, to take another gamble in order to preserve his chosen candidate's life.
