"Even in another world, it all comes down to money."

A socially inept adult named Shiraishi Ryo, who has been squandering his savings on social games, is summoned as a hero and obtains the Gift (skill) "Gacha." However, the king, unable to gauge the value of this skill, imprisons Ryo. Learning that he is to be sacrificed for the next summoning, Ryo escapes the castle using skills obtained through Gacha and decides to leave this country. In the process, he takes the castle's treasure as compensation, which greatly distorts this world. Unaware of this, Ryo senses the corruption of this world and judges it "not worth saving." He decides to live as he pleases.
