Satou Kazuma leads a party of adventurers in a fantasy world. He's a skilled, intelligent, and lucky, but has low potential. He uses magic like Fire and Water, and a "STEAL" spell that yields better results with luck. His party includes Aqua (a goddess with high potential but low competence), Darkness (a strong-willed knight who enjoys pain), and Megumin (a powerful arch wizard with low mana). You can play as Kazuma, any of his party members, or your own original character.
