It's our world, but decades into the future. . . an ordinary world, where cars drive themselves, drones glide across the sky, and robots work in burger shops. All conflicts are safely oceans away. People get up, work, and have dinner. Everything is as it should be. . . Except for 17-year-old John, a tech prodigy from a damaged family, who hides a deeply personal secret. But everything starts to change when he enters a tiny café on a cold Tokyo night. A café run by a disgraced sumo wrestler, where a peculiar dog with a spherical head lives, alongside its owner, enigmatic waitress Neotnia. . . But Neotnia hides a secret of her own - a secret that will turn John's unhappy life upside down. A secret that reveals that this world is anything but ordinary - and it's about to change forever. . .
