I Don't Have Any Powers but I'm Called the Strongest One

A meteorite that was powerful enough to destroy the Dragon Kingdom fell, bringing with it a visitor from another world who thought he had lost his memory. The visitor from another world who lost his memory began his journey in this new and unfamiliar world in order to travel through his own memory. During his travels, he came into contact with unknown supernatural beings. Until one day, the college beauty who was in the second year of high school asked the visitor from another world: "Are you a person with superpowers?" The visitor from the outside world said: "I don't have superpowers." The military boss asked the visitor from the outside world: "I know you have superpowers, you don't have to hide it." The visitor from the outside world said: "I don't have superpowers." The world's strongest superpower looked in disbelief at the visitor from another world who easily defeated him in seconds and asked unwillingly: "I lost, but before you die, can you tell me your superpower?" Facing these people who didn't listen to him, the visitor from another world sighed helplessly: "I really don't have superpowers."
