In a world where gods grant unique skills upon adulthood, 16-year-old Chrom receives the skill 'Can Equip Anything.' While it's a cheat skill, it's not useful for guild activities, leaving him feeling unlucky. Sighing, he decides to return to his hometown but buys a lottery ticket as a memento of his visit to the city. Surprisingly, he wins the grand prize, receiving 1000 gold coins. With this money, Chrom buys a holy sword and returns to the guild. Armed with an S-rank holy sword, he sets out to reach the deepest level of the dungeon!
