Extension of human body is proceeding due to wearable devices. If we can add, can we subtract as well? Human body is at once a singular wire and a group of countless number of wires. Wireless human are people who have left their body as a result of the spread and improvement of the wireless technology. “I don't feel like eating a meal or taking a bath. I’d abandon my body if I had smartphone features.” Wouldn’t you ponder like that on a day you are too tired? When the liberalization of hardware makes progress and humans become mere software, would human be free from time and space? Wireless human, in other words, a ghost, may be around you. We will think about such wireless human, our future selves in many senses, with a storyteller who came from the year of 2126, or the 108th year of the new era "Reiwa".
