The protagonist was a patient with ALS on Earth. Reborn in another world, he gained a perfectly healthy body. He turned down every powerful combat class and chose the most scorned one: [Wanderer]. To him, the ultimate treasure in this world isn't power, but "experience": the feel of the wind, the taste of good food, the freedom to run. Yet his game, played purely for the sake of "experience," often leads straight to the very essence of the world.
