One man's story of turning blood, sweat, and tears into a successful living--literally! After his untimely death as the hardest-working salary man in Japan, Luciel is reincarnated into the magical fantasy world Galdardia. Always the man with a plan, he recreates himself to be a healer, and sets about making his way in the world. But while Luciel knows a thing or two about making money, he knows absolutely nothing about Galdardia. Will his good heart and great work ethic be enough to make him...The Great Cleric?With the help of the Adventurers' Guild, Luciel uncovers the mastermind behind the attack on the healers. And, once again, it seems as though fate is pushing him towards the newly-awakened Labyrinth--the source of all Yenice's recent troubles. Luciel and his allies venture into the Labyrinth, but strength alone won't be enough to make it through this time. If they want to leave the Labyrinth alive, they'll need to work together, get creative, and fight with some "substantial eXperimentation."
