The Anime Lad
Mukouda Tsuyoshi is an ordinary salaryman abruptly transported to another world. His unique skill is Online Grocery, which initially appears less useful than a heroic gift should. It lets him bring modern food into his new surroundings, where those products have surprising effects. Fantasy logistics have been disrupted by reliable access to the pantry.
Super Eyepatch Fox
Mukouda arrives in a fantasy world without a grand combat ability. Instead, Online Grocery gives him access to modern food. What seems useless becomes strange leverage once those familiar products meet unfamiliar surroundings. The series builds its premise around a salaryman's practical skill and the unexpected value of an ordinary meal far from home.
Gigguku
Of all the powers Mukouda could receive in another world, he gets online groceries. Perfect. He can bring modern food into a fantasy setting that has no reason to expect it, and even familiar ingredients gain absurd possibilities. I love that the premise points toward cooking and appetite instead of conquest. The humble pantry has entered the adventure genre!
Father's Basement
A magical shopping interface removes a great deal of inconvenience before the story begins. That is the point, but it is still suspiciously tidy. The more appealing choice is what Mukouda does with it. Modern food becomes his odd advantage, shifting the fantasy away from another chosen fighter and toward the practical consequences of bringing ordinary products somewhere new.
