When Tsuyoshi Mukouda gets whisked away from modern Japan to a realm of swords and magic, he's convinced he's in for an epic journey. However, the kingdom that summoned him made a colossal mistake – he's not one of the chosen heroes and his abilities are a joke compared to theirs. Sensing foul play, Mukouda sets off on his own path in this new land. Armed with his special skill, the 'Online Supermarket,' he can purchase modern goods in this medieval world. Though useless in battles, this skill could pave the way for a comfortable life, or so he hopes. Little does he know, the food he introduces from his world carries bizarre effects. As he tantalizes the locals with delicious modern cuisine, Mukouda unwittingly garners a fanbase clamoring for more of his culinary delights.
