A middle-aged salaryman gets isekai'd and decides the only rational response is to stop trying to be a hero and just cook. Modern food hits different in a fantasy world, and watching him feed curious adventurers convenience store snacks while they lose their minds over the taste is the entire show. No world-ending plot waiting to ambush you, no chosen-one nonsense, just a man grilling meat over a campfire and finally being content with something small.

Salaryman Mukouda Tsuyoshi is accidentally summoned to the Kingdom of Reijseger alongside three genuine heroes, and his stats look pitiful next to theirs. Suspecting the royals want to exploit him, he slips away using his only unique skill, Online Supermarket, which lets him buy cheap food and utensils from Japan. It seems worthless for fighting, but the modern food turns out to have absurd effects in this world. His cooking wins over Fel, a fearsome legendary wolf who quickly makes a contract to become his familiar. With Fel at his side, Mukouda travels and makes a living as an adventurer and merchant in this comedic fantasy adventure.
