Tetsuya Goto transmigrates to a parallel world and becomes a police officer in Tokyo. He is assigned to pose as a street-food vendor and keep an eye on a suspect.
Soyo Nagasaki: "Let me buy another serving of mapo tofu, and I'll do anything!"
Tomori Takamatsu: "Could you set up your stall outside my house for the rest of your life?"
Hitori Goto: "I'm getting a little too popular. I think they're all craving big brother's cooking..."
Suspect: "I just fought someone over a serving of mapo tofu. Am I really getting thirty years?"
Tetsuya Goto travels all over the country, solving countless major cases. Criminals are even willing to risk getting caught just to have a bite of his cooking.
"I've even kicked that stuff, but I can't stop thinking about your tofu trio. Please, just let me have one bite!"
In this way, Tetsuya Goto becomes the bane of criminals in the police force... Beside him, Conan looks like a rookie.
