A high school student, who likes to camp solo, travels around the other world freely! One day on his way home, he is summoned to a different world. After graduating, he decides to go on a trip somewhere far away, and he thinks, “This means I can go on an indefinite wandering trip to a different world in the style of medieval Europe”. He decides to return to the other world after enjoying the unknown world of swords and magic, and blends into the other world at an astonishing speed, using magic and physical enhancement at will. What’s more, it seems that the magic he can bring to life by utilizing his knowledge of survival on Earth is far beyond the common sense of people in other worlds. What kind of magic was that?
