For those unfamiliar, isekai is a sub-genre of anime and manga technically dating as far back as the 1970s, though its really come into prominence in the last decade or so. The basic concept is that some schlub from our world gets himself inadvertently transported to a fantasy land, usually one vaguely reminiscent of Dragon Quest, and often gets some manner of overpowered ability. In a statistically-significant number of these stories, the way in which said schlub gets FedExed to the other world is by meeting the business end of a runaway truck. Its so common that the trope even has a name: Truck-kun.
