The story is set in a distant future, where the Earth has been evacuated and humanity now inhabits a man-made ring-shaped city orbiting 35 kilometers above the planet's surface. The ring is divided into floors, of which there are three; the first being the living space of everyday workers, the second being dedicated to agriculture, and the third being the dwellings of the upper class. The plot follows the life of a young man called Mitsu, whose job as a window cleaner allows him a glimpse into the lives of the ring's inhabitants, as he attempts to learn more about his father's disappearance while working in the same job.

• Mitsu • Mitsu works as a window cleaner because he takes joy in it and because he wants to learn about his father's ill disappearance at work. He tends to be of a very calm nature, and he is very dedicated to his job, something he is aware of as being a dangerous and low-paying occupation. He is somewhat inexperienced and insecure of himself. • Aki • Mitsu's late father, who raised the latter by himself until his untimely death during a job when the rope dangling him snapped. Since Mitsu was very young at the time, much of Aki is told from his friends and colleagues, upon many of which he had a profound influence on. • Jin • Jin is Mitsu's superior and occasional supervisor who has had plenty more experience working as a window cleaner. He tends to speak gruffly and is externally of a brash nature, however he is caring for his co-workers. He lives with his wife, Haruko, and is a close friend of Tamachi (even though they dislike admitting it). • Makoto • A co-worker of Mitsu who has a grudge with him for "replacing Tamachi" and for "having it so easy" in terms of work.

• Haruko • Jin's wife. Haruko is frail and prone to blackouts due to what is described as an autoimmunity deficiency caused by a lack of sunlight in the lower levels. In a flashback it is revealed that she dislikes hospitals due to an accident that led to her sterility. This doesn't stop Haruko from being cheery and from participating in public agriculture. • The Kageyamas • A family of three that occasionally house Mitsu. The family is integrated by the bald and boisterous Mr. Kageyama (who is also a window cleaner), his wife, and their daughter Fuyo. • Tamachi • Tamachi once worked as a window cleaner and was the former partner of Aki (Mitsu's father) until the latter's death, whom he blames himself for. He now works in a bio-gas plant with his friend Sohta. • Sohta • Sohta is an aspiring scientist who lives with his wife in the lower levels, and works with his friend, Tamachi, at the gas plant. It was his honeymoon request for a lower-level window to be washed where Mitsu's father, Aki, died. • Sachi • An acquaintance of Mitsu who works as a "falling objects researcher". She was originally mistaken as a man by Mitsu. She and her pet cat live outside of the ring on a small cabin, and the exposure to solar radiation gives her constant sunburns.
