In a world where the mightiest prevails, a kingdom about to enter a war decides to summon heroes from another world.
Tsuyoshi is a salary man in Japan, and suddenly he appears in a room surrounded by people he doesn’t know, and in front of him, there are three young persons who are quickly named heroes.
Before they can explain what is happening, a magician decides to evaluate their special abilities, and sure enough, the three guys in front have extraordinary powers, and Tsuyoshi has an ability named “Online Supermarket”.
In front of the king, Tsuyoshi tells him that apparently he has been summoned by mistake and that his abilities are not worthy of a hero and asks him to withdraw from the room. Fortunately, they take pity on him, and even give him some money so that he can pay for his expenses.
Immediately, Tsuyoshi seeks to avoid attracting attention and buys clothes and finds accommodation. He realizes that something is not right, and decides to leave the kingdom immediately.
That night, he decides to test his magic ability, and finds out that the Online Supermarket is exactly that, and that with money, he can buy all kinds of ingredients and tools, just like he used to at home.
He discovers that his ability to appraise people, abilities and objects is really strange, so he decides to keep it a secret. And when he is about to embark on a journey to leave the country, he discovers that the borders have been closed to list men to participate in the war.
Tsuyoshi decides to hire a group of adventurers to guide him out of the country, so he goes to the guild and offers a nice cash and meals reward in exchange. And thanks to his ability, he can buy ingredients to prepare food anywhere and at any time.
As the days go by, the adventurers look forward to their next meal, they have never tasted what Tsuyoshi offers them, and after defeating a huge boar, they hope to have a feast.
Tsuyoshi notices that the adventurers look more cheerful and stronger, and by using his appraisal ability, he realizes that the food he serves not only feeds them, but also increases their powers.
That night, everything seems to be in order, and the dish prepared by Tsuyoshi is delicious. Suddenly, behind Tsuyoshi appears an imposing magical creature named Fel.
Fel has been following Tsuyoshi’s group for a couple of days and tonight the smell of food is irresistible, so he doesn’t hesitate to demand that he offers him a plate.
Tsuyoshi hesitates to listen to him, but seeing how scared his bodyguards are, he decides to offer him food. Fel immediately devours the portion and asks for more, to such an extent that the boar they had just hunted earlier is finished.
Fel tells him that from that moment on, he has decided to become Tsuyoshi’s familiar and asks him to come over to formalize the contract, the adventurers tell him to obey and by doing so, Fel tells him that from that moment on he will look forward to every one of the three meals of the day.
