Mukouda Tsuyoshi is an ordinary office worker swept into a fantasy-world summoning ritual he wasn't invited to, and the kingdom that wanted a hero has no use for the one skill he actually gets: an Online Supermarket that lets him order groceries from Japan. Useless in a fight, the skill turns out to have a different kind of pull, because his companions Sui, Fel, and Dora-chan keep showing up for whatever he's cooking, and so does everyone else who catches the smell. This light novel is the source material for the Campfire Cooking in Another World anime.
