In an era where Divine Cores awaken, high schooler Wyatt Mercer awakens the lowest of the low — a Grade-F God of Gastronomy. Mocked and expelled from the academy, he's left with only one mission: save his gravely ill sister, Cora. To survive, he sets up a stall selling stinky tofu. But when a customer's Core unexpectedly strengthens after eating his food, Mercer discovers his secret power — whoever eats his cooking with satisfaction signs a pact, lending him their divine power. From there, Mercer rises through the ranks, and proves that even the weakest god can feed the strongest — and make them kneel as well.
