Fortune Quest: Yo ni mo Shiawase na Boukensha-tachi

Fortune Quest is the tale of a bunch of adventurers. Imagine your classic D&D party--Fighter, Thief, Bard, Mage, Healer....and Porter? Okay, don't know where the Porter comes from, but Pastel and her group of adventurers are broke and need a job. They can't afford to buy any of the adventure modules from the module seller, so they have to take part-time jobs to pay off their debts. And an innocent job to fetch holy water leads to world-threatening danger...and a white dragon.
